 March 15, 2022 - The Lunar Eclipse

    I have done nothing astronomy related of late but the lunar eclipse prompted me to dust off my Cannon T5 rebel, 300 mm zoom lens, and tripod and give a go a photographing the eclipse.  I had to review the camera's manual to remember how to adjust the settings for night time photography.  I got a few decent shots but near totality I had trouble focusing on such a low light image so the images are a bit fuzzy.  Anyway here is what I got.

The beginning

  About half way

Start of the red coloration

About 3/4s eclipsed

Near totality


Others no doubt have better pictures but this my record of the eclipse.  Until next time....

Where have I been?

 I have taken a hiatus from astronomy for the past couple of years to delve into my other hobbies: model railroading and computer programming.  Also I have been selling my late wife's collection of Beatles memorabilia.   The collection included over 1,000 items and they were not cataloged.  So I've been cataloging and selling items via the website  Selling The Collector's Collection.  

I don't have a web site yet for my model railroad but I have made quite a bit of progress on the layout recently.  Here are a few pictures of the layout.  It is far from complete and I feel pressure to get the trackwork completed as I'm not getting any younger.

I've spent a lot of time programming for the first time since the 1980s.  I became intrigued by the very large data sets required by modern games like Clash of Clans.  I played around a bit with a spreadsheet building maps & supporting data sets and then I decided I wanted to program a basic game to use the data.  So.. I looked around and decided to learn the programming language C++.  I had a little familiarity with the C language back in the 80s but hadn't touched it since.  I learned enough to get the small game working but I wasn't happy with the user interface, so I switched to the Java language.  It's syntax is similar to C but I had to overcome a big learning curve.  With Java and the tools provided by the Apache NetBeans Integrated Development Environment, I was able to rewrite the game with a nice windows-like interface.   I got it working and it looked pretty good, but I am a poor game designer.  No one would want to play the game, but I learned a lot and had fun.  I was looking for a new programming challenge.

Since 2018 I have been regularly operating on Art Houston’s Grande Pacific model railroad. Almost every week, 4-6 people gather at Art's to run trains on his layout.  Art uses JMRI Operations to manage his car movements to the numerous industries around the layout. He typically uses Dan Foltz’s Manifest Creator to generate train manifests and JMRI to create location switch lists for the operators. Art's system works well and the operators all enjoy running trains on his layout, which was designed for operations. In the fall of 2020, Art mentioned Manifest Creators’ dependence on Excel and how Microsoft was now charging an annual fee for Excel as part of their office suite. I told him that I was looking for a programming project and I would see if I could develop an alternative to Manifest Creator written in Java, a free program, which is what JMRI is programmed in. The result is Model Railroad Switch List and Manifest Formatter.

I do plan to get back to astronomy in the future but for now I'm focused on building my model railroad, selling the Beatles' collection,  and supporting the users of my computer program.

2019 DSSG, Day 2

After the frustrations of the first night of the DSSG I was ready for a good night on Wednesday, Oct. 23, 2019.   I had figured out the causes of my issues, they were mostly of my own making, and was ready to go as the sun set.   After aligning the Rigel finder scope with an eyepiece,  I installed the camera.  For some unknown reason on Tuesday night the camera focus was at 12 mm versus the typical 17 mm.  On this night the focus point was back near 17 mm.  Perhaps last night I didn't have the camera fully seated into the focuser.  I spent some time tweaking the focus as it looked a bit soft,  but finally I stopped on the best I could achieve.

After aligning the mount with the polar scope, I fired up SharpCap and started capturing images to refine the polar alignment of the mount.   For some reason SharpCap couldn't solve the images.  I haven't had this happen previously.  After several tries, I gave up and just relied on the polar scope alignment.  Building the pointing model went smoothly as all the gotos were very close.

I started off the evening with an old friend, The Owl Cluster, also known as the E.T. cluster in Cassiopeia.   
(NGC 457) 4 x 60 sec frames, no darks or flats  Gain = 300

I then continued my project to image both Herschel 400 observing lists.   Most of these are very small (< 2 arcmin in diameter) so I'll not include all the images here, but I captured; H 79-1 (NGC 3147), H 288-1 (NGC 2655), H 78-1 (NGC 2985), H2 578-3 (NGC 1207), H2 607-2 (NGC 1175),  H2 43-8 (NGC 1750),  H2 8-2 (NGC 1587), & H2 34-5 (NGC 1990).  

H2 578-3 (NGC 1207)  6 x 3 min exposures @ gain = 300, no darks or flats

H2 43-8 (NGC 1750)  8 x 60 sec exposures @ gain = 300, no darks or flats

H 288-1 (NGC 2655)  8 x 3 min exposures @ gain = 300, no darks or flats

H2 8-2 (NGC 1587)  9  x 3 min exposures @ gain = 300, no darks or flats

At 1217 am I measured the sky brightness as 21.12 = 6.18 NELM.   A nice clear humid night.  The dew while bad, was not as bad as last night.  

With Orion rising in the east, I decided to try and capture the Flame and Horsehead Nebulas.  The focus is a little off and the guiding wasn't great, but a nice image of a beautiful portion of the night sky.

The Flame Nebula (NGC 2024) and The Horsehead Nebula (B 33)
27 x 120 second exposures @ gain = 300, no darks or flats

With the forecast for rain late Thursday through Saturday, I got up Thursday morning, packed up my gear and headed home.   As always, I had a great time at this star gaze.

2019 DSSG

The 2019 Deep South Star Gaze is held at the White Horse Christian Camp in Sandy Hook, Mississippi.  Tuesday, Oct. 22, was a beautiful day for setting up although a bit windy.  There were about 20 scopes setup for Tuesday night.

Westward look at the observing field

My setup - Explore Scientific ED127CF riding on a Losmandy G8-11.

As darkness fell the temperature fell into the 50s and the sky was nice and clear however the humidity was a high.  By midnight the temperature dipped to  46 and everything was wet with dew.  

Having not viewed for many months, I was quite rusty and fought focus, guiding, and dew problems most of the night.  I was cold and tired but I managed to get a half-way decent image of the great Orion Nebula (M-42), its companion nebula (M-43) and also the running man nebula (NGC-1977).   The stars are a bit elongated owing to the poor guiding, but AstroToaster stacked the images well.

19 x 30 seconds exposure ED 127 mm triplet at F 7.5.  

Hopefully the weather will be good again tonight and I can remedy my issues and get some imaging done.

2018: Year in review

As I sit here to write this on New Year's Eve, it is cloudy and rainy again as it has been much of the fall and winter. There have been a few clear nights during the year that I chose to pursue other activities, but there weren't many prime observing opportunities in the second half of the year. Still I achieved a few astronomical accomplishments in 2018.

  1. First light for my upgraded ASI071MC-Pro camera was Jan. 3, 2018.  I found that the upgraded version is less susceptible to frosting.
  2. Received my new Explore Scientific 127 mm CF apochromatic refractor with FCD100 glass and a Losmandy G811 mount with Gemini II. This will be my travel imaging rig so I don't have to disassemble the observatory when traveling to a star party.
  3. Determined that a Tripp-Lite model U330-10M superspeed active extension cable works to connect the ASI071MC- Pro camera to the laptop. This long cable doesn't drop frames at a frame rates of > ½ second and the supplemental power supply is not required.
  4. In April I attended the Deep South Spring Scrimmage at Feleciana Retreat. First use of my ES 127 CF apo and G811 mount. Got in 2 nights of viewing before heading home due to the forecast for severe weather.
  5. Learned to improve my images through the use of flat frames taken with an Electroluminesient panel. This works very well to remove dust and other artifacts from the images.
  6. In August I attended the DSSG trial run at White Horse Christian Retreat.
  7. In October I went to Fort Davis, Texas with Dave & Scott.  We had a great time observing from really dark skies and visiting the McDonald Observatory.  Photos in my Flickr account.
  8. Got the Rigel nStep focuser motor working on the observatory scope.  The USB cable for it requires an auxiliary power supply for consistent operation.  I purchased an nStep focus motor and for the travel scope.
  9. I recorded 104 astronomical observations during 26 observing sessions in 2018.
  10. Completed the underground cable piping in the observatory and ran the USB & Ethernet cables from the mount to the office.  All works fine and no more trip hazard!

And now for a sampling of my images from 2018;

Observatory Update

At long last I'm updating my blog.  I've been active in astronomy but have neglected to update this blog for over a year now.   At a later date I'll post some of my recent adventures (pre-DSSG trip to White Horse Christian Camp and a trip to Casa Mano Prieto).  For today a simple post to show the completion of a project, long overdue - Completing the underground cable piping from the pier to the office.  When I built the observatory I installed the piping at the pier and ran it underground to just outside the office wall.  And there it sat for 2 years while I draped cables across the floor.  Finally today I got out the shovels and routed the pipe up through the office floor.  It was not nearly as hard a job as I anticipated.

Next I fished the 2 USB cables (camera & focuser) and ethernet (mount) through the pipe and into the office.

Here you can see the pipe extends about 1' above the office floor and beneath the desk.

So now my cables are conveniently laying on my desk top waiting to be plugged into my laptop for an observing session.  

Since no astronomy blog post would be complete without at least one astro image, here is my image of NGC 1514, The Crystal Ball Nebula in Taurus.  I took this with my Explore Scientific 127 CF at prime focus with my ZWO ASI071MC-Pro camera.  The image is 11 x 5 minutes with no darks or flat frames and no post processing.  The image was taken at Casa Mano Prieto in Fort Davis, Texas on Oct. 14, 2018.

Till next time.

July Observing Report

July 1, 2017
I had been wondering about the odd Herschel designations for objects in Deep-Sky Planner. Most places just reference the NGC #. I found informative web page on Herschel that provided the following explanation. <>.

He invented the following classification scheme for nebulae and star clusters, based on the appearance of these objects as he perceived them, rather than physical properties:
  1. Bright Nebulae
  2. Faint Nebulae
  3. Very faint Nebulae
  4. Planetary Nebulae
  5. Very large Nebulae
  6. Very compressed and rich star clusters
  7. Compressed clusters of small and large (i.e., faint and bright) stars
  8. Coarsely scattered clusters of stars
William Herschel compiled his lists with running numbers for each object type. Because of the missing physical meaning of this classification, it is of historical importance only.

So H 53-4 (NGC 1501, the Oyster Nebula, a planetary nebula) was the 53rd planetary nebula that he cataloged. The Astronomical League's web page also contains good information on Herschel and his nomenclature. <>

Another hot, muggy night in SE Louisiana, at least there are no clouds. I built a new dark library PhD2 from 3 to 6 seconds, 10 exposures each. I'm going to take a different approach to cooling the ASI071MC-COOL by setting to 0, but no lower. I've slowly cooled from ambient to 10, 5, and 0. Hopefully this will avoid fogging of the windows with the window heater and aux heater on. To start I took 5 darks of 3 min, Gain 400, temp 0 C with the color balance as it was last night (Gamma 100, brightness 8, R bal 60, B bal 99).

Note that I have yet to drop a single frame on this computer. Makes observing more enjoyable. With the darks done I'll continue with the Herschel 400 objects in Ophiuchus. At 2137 it is 78 F with 88% humidity.

H 12-6, NGC 6293
A circular GC in a dense star field. Interestingly there are numerous stars in the GC or between the GC & Earth that are much larger than the majority of the stars in the GC. The core of the cluster is unfortunately blown out.
I tried to use just SharpCap to stack & adjust but I find the interface a bit clumsy and in switching from the stack screen to the histogram, the program froze & I had to kill it. I collected 6 x 3 min exposures with gain=400 and stacked in AstroToaster. I'm at 50% on the histogram so more signal than I typically collect. No stars are blown out but the core is blown out. I should have reduced the exposure and/or gain to get a better image.

6 x 180 sec, gain= 400, Temp =0C , dark frame subtraction

H 147-1, NGC 6304
A bright, tight GC in a very dense star field. The core is not circular but almost rectangular. I've blown out the core badly with a stack of 5 x 3 min at gain=400. The star field is so dense it is hard to tell where the GC ends. The FOV is littered with larger, brighter stars. The star field is densest to the SE of the GC.

I think the reddish tint is a fog forming on the camera window or chip. When I up the gain on the AstroToaster image you can see it. I'll try raising the camera temperature to 5 C.

5 x 180 sec, gain = 400, Temp = 0C, dark frame subtraction

H 149-1, NGC 6342
The reddish cast is largely gone in these frames but the image looks washed out and foggy. The histogram max lies at 35 and the colors are nicely correlated.
An interesting GC as it has 2 linear extensions to the S. The core is rather diffuse with discernible stars around the core. The extension on the SW side is the most prominent with 2 bright lobes and an intermediate semi-bright lobe. The extension to the SE has only 1 semi-bright lobe nearest the GC and then 3 fainter lobes. The star field is dense to the E and especially the SE. There is a single large bright star near the NW corner of the FOV. 

5 x 180 sec, gain = 400, Temp = 0C, dark frame subtraction

Note that these images are captured in SharpCap and stacked, adjusted, and saved from AstroToaster.  No post processing was performed unless explicitly stated.

H 11-4, NGC 6369
This is a faint, 11.4 mag, planetary nebula and it is only 37.8''. This will be a bit of a challenge for a 3 min image.  First frames look quite nice, like the ring nebula only smaller and the central star is more obvious. The width of the ring halo is about double the size of the central hole. Unlike the M 57 ring nebula, I see no color in this nebula. No structure is discernible in the halo. In the HST picture there is nebulosity on opposing sides of the nebula about the width of the halo away from the halo. I can see hints of this in the N & S of the nebula but it is not clear in the pictures. There are 2 bright stars in the FOV. One is near the NW edge and the other is NE of the nebula by around 10 minutes.

11 x 180 sec, gain=400, Temp = 0C, and dark frame subtracted

H 46-1, NGC 6355 & H 44-1, NGC 6401
These objects are low in the SE and I appear to be getting a reflection off the top of the observatory wall. (I need to paint the top rail flat black to help avoid this.) I can see the clusters but can not make out any detail due to the bright reflection. Will try these again when they are higher.

H 199-2, NGC 6517
This object is higher up in the sky so I hopefully will avoid the reflections that plagued the observation of the previous 2 objects.
Easily spotted GC in a star field void of any large, bright stars. The GC has a small bright core and a star cluster that looks more triangular than circular. This is evident in some of the pics on the internet of this object. “Spokes” of the GC point E, NNW, and SSW. To the NNE there are 2 arcs of stars bending off to the SE. 

6 x 180 sec, gain = 400, Temp = 0C, dark frame subtraction applied

At 0034 it is 72 F and 98% humidity. Sky meter reading is 18.43 with a half moon low in the SW.

I got all but 2 of the Herschel 400 objects in Ophiuchus. Will try to nab the last 2 tomorrow night.
Shut down at 0048.

July 2, 2017
Set up around 2050 on a hot, humid night with clear skies to the E but a few clouds in the W. I don't plan on viewing to the W so we should be OK. My primary goal is to knock out the two remaining Herschel 400 objects in Ophiuchus but I'll need to wait until around 2300 for them to be high enough.
Built model from Vega, Ras Alhague, Kornoeouphus, Antares, & Mizar. I then added Altair and a goto Ras Alhague failed to put it in the FOV. I removed Altair from the alignment and went to Vega, it is NW of Center just outside the second circle of the ShapCap reticle, which is probably around 5 arcmin. Not great but I'll go with it. I have the dew shield on the scope tonight to minimize dew and reflections. I left the camera temperature at 5 C to avoid freezing and/or dewing on the chip window.

H 46-1, NGC 6355
A GC in a densely populated star field except for the Eastern edge of the FOV. The cluster is easily spotted and has a bright core with discernible stars. It is circular in shape with a line of stars on the N edge running W-E made up of around 10 stars. There is a large bright star, perhaps a double, about 25 arc min to the W of the GC.
6 x 180 sec, gain = 400, Temp = 0C, dark frame subtracted

At 2300 it is 79 F and 92% humidity. Sky meter reading is 18.38 with the half moon in the SW.

H 44-1, NGC 6401
Got one frame and then clouds started rolling in and PhD lost its star. I may just have to be satisfied with the couple of frames I got.
This GC doesn't appear to be round but is flat on the NNW side. There is a large bright star on the SSE at the edge of the GC. The GC has no discernible core. The stars are uniform and faint except for 3 bright stars on the NW edge running E-W. The star field is fairly dense especially to the S. There is a large dark area (dark nebula?) to the SE and more smaller dark regions to the NE & NW. These dark regions are seen in pics on the internet and thus not an artifact of my image.
 9 x 180 sec, gain = 400,Temp = 0C, dark frame subtracted.

I only got 2 objects done, but at least I finished off the Herschel 400 objects in Ophiuchus. I've now bagged 162 of the 400 objects or 40.5%. Shutdown at 2333.

July 3, 2017
Another hot, muggy night in SE LA, but at least it is reasonably clear. There are periodic fireworks going off around the area and a big display by the parish to the NW, so I won't look in that direction.
Setup is the same as the past couple of nights; 10” RC at F8, no focal reducer, ASI071MC-Cool imaging camera at prime focus. Lumicon Deep Sky filter. Orion 80 mm F5 guide scope with StarShoot autoguider camera. Pier mounted Losmandy G11 with Gemini 2 controller. I synced the model on Antares and off I go, although at 2107 it isn't yet quite dark.

H 196-2, NGC 5694
Trying this object although it is rather low (33 degrees) in the SW.  A small (1.2')circular GC with a small bright core. Several stars are discernible around the periphery of the GC but the center is blown out. To the SW there is a linear extension of a few stars. There are 2 large bright stars to the NE of the GC about 1 – 1.5' away.
10 x 60 sec exposure, gain = 400, Temp = 5 C, no dark frames were subtracted.

H 402-2, NGC 6118
This is a faint (11.7 mag) object that is within 30 degrees of the > ½ moon. May not have enough contrast to pull it out of the sky glow. I can see the shape of the galaxy's halo but not discern any detail of the arms. There is a bright core and an elliptical halo that is roughly twice the size in the NE & SW directions as in the NW & SE. There is a line of 4 stars, probably foreground stars, across the NE end of the galaxy running NW to SE. The star field is moderately populated with uniform density, size, & brightness except for 1 brighter star NNE of the GC roughly 20 arcmin away.
10 x 180 sec, gain = 400, Temp = 5C, no dark frames were subtracted.

At 2246 it is 78 F & 88% humidity. Sky meter reading is 18.49 with a > ½ moon in the SW.

H 10-6, NGC 6144
A large (in my FOV) GC with no detectable core and many discernible stars. In stack of first 4 frames I had egg shaped stars. The mount is leaning pretty far over and part of the scope is blocked by the observatory wall. The stars are egg shaped in single 2 min images so I don't think I'm going to get a decent image. I'm not going to record this observation in Deep-Sky Planner as I need to observe the object again to catch a better look.
4 x 120 sec, gain = 400, Temp = 5C, no dark frames were subtracted

H 47-1, NGC 6712
Wow, hard to believe this object wasn't a Messier or Caldwell as it is big (~ 3 x 4') and bright in a very dense star field. It is hard to discern where the GC ends in this dense star field. The GC isn't circular, at least from the image. It is flat on its NE edge. This is also shown in pics on the internet. There is no bright core to this GC but there are a dozen or so bright stars around the object, but they could be foreground stars. There is a bright star, much more so than the other stars in the FOV, about 5 arcmin to the SSW.
7 x 120 sec, gain = 400, Temp = 5C, no dark frames were subtracted

H 18-7, NGC 6823
Last object of the night, an open cluster in Vulpecula and there appears to be a dark nebula in the DSS picture. Will see what I can pull out.

A very nice bright cluster in a sea of red nebulousity with dark nebulas running through. The cluster has 3 close bright stars at its center with other bright stars in the region and many more smaller stars. The cluster is surrounded by a red nebula with dark lanes and regions (dark nebula?). One prominent dark lane is 5 arcmin SW of the cluster. The surrounding star field is densely populated.
8 x 120 sec, gain = 400, Temp = 5C, no dark frame subtraction

I was afraid I would have star streaks in the above images as I kept loosing the guide star due to clouds rolling in. The sky is now covered and I shut down at 0012.

July 5, 2017
Targets for tonight are the remaining objects in the constellations Vulpecula. If time allows the objects in Scutum and Sagittarius will be next. Same setup as on July 3. It is 84 F with 72% humidity at 2055. The skies are clear but the moon is 4 days from full and is thus shinning bright and high in the SE. Did a goto on Alberio and it was very close to center of FOV so I did not do a sync. Onto the first object of the night.

H 14-6, NGC 6802
A stack of 5 x 90 sec images show the cluster nicely in a dense star field, but many of the stars are quite faint so I increased the exposure to 2 min. Interestingly the cluster is not circular but rectangular running SW to NE. It is roughly 5 x 2 arcmin. The cluster consists of 2 brighter stars along the S edge of the cluster. The other stars in the region are quite uniform.
The star field is densely populated with 2 larger stars about 5' to the NW of the cluster. About 10' to the E is a broad (15') curved structure consisting of a dozen stars. There are also collections of brighter stars about 15' to the SE
9 x 120 sec, gain = 400, Temp = 5C, no dark frame subtraction

H 9-7, NGC 6830
A sparse cluster approximately 27 stars arranged in a pattern resembling the numeral 3 with several fainter stars. The star field is densely populated. There are 2 brighter stars around 5 arcmin to the SSE.
8 x 120 sec, gain = 400, Temp = 5C, no dark frame subtraction

H 22-8, NGC 6882
A large loose cluster that is marked by a large bright star near the S border, although the borders of the cluster are hard to discern. There is a circle of stars about 3 arcmin in diameter to the NW of the bright star by about 5 arcmin. Around this bright star are 11 stars of intermediate brightness and many more fainter stars. 20 arcmin to the W of the central star of the cluster is a much larger brighter star that I believe is 20 Vulpecula.
6 x 120 sec, gain = 400, Temp = 5C, no dark frame subtraction found this image to be 40.5 x 26.9 arc min with 0.492 arcsec/pixel. It said that the object in the center of the FOV is NGC 6885 with 20 Vul being the central star. It says that NGC 6882 is around the very bright star to the WSW, what I thought was 20 Vulpecula, but calls it 19 Vul. The Sky Atlas 2000.0 also shows NGC 6882 around 19 Vul and 6885 around 20 Vul.
Crap, clouds are starting to roll in all around. Hopefully I can finish the objects in Vulpecula.

H 20-8, NGC 6885
The image captured is nearly identical to the one for NGC 6882 so the Gemini system has the same coordinates for these two objects.
6 x 120 sec, gain = 400, Temp = 5C, no dark frame subtraction

Found this info on
NGC 6882/6885- open clusters NGC 6882 and NGC 6885 may or may not be the same item. William Herschel discovered them on successive nights and gave almost identical descriptions. General consensus is they are the same object. To complicate the story further, Per Collinder included a small scattering of stars to the northwest edge of NGC 6882/6885 as number (Cr) 416 in his catalogue of open clusters.
NGC 6882/6885 is grouped around mag. +5.9 star 20 Vulpeculae and consists of up to 40 stars. The rough diameter of the cluster is about 20 arc minutes with the more compact cluster Cr 416 located at the northwest corner (diameter 8 arc minutes). NGC 6882/6885 shines at mag. +5.5, with Cr 416 fainter at mag. +8.1. All in all, the whole area contains a nice grouping of stars centred on bright stand out star, 20 Vulpeculae. Binoculars show the main stars and give a feeling for the area, medium and large size telescopes reveal much more. To some, the region appears as just one large group of stars.
In his book Deep Sky Companions: The Caldwell Objects, author Steve O'Meara, in chapter 37 discusses the NGC 6885 / 6882 confusion in detail but provide no resolution: 2 objects or 1.

H 8-7, NGC 6940
A large star cluster centered on a bright reddish star in dense star field. Difficult to discern where the cluster boundaries are. I can discern no patterns or asterisms in this cluster. It appears to be oriented NE to SW and covers almost the entire FOV. It is cited to be 25 arcmin and my FOV is 40.5 x 26.9 arc min, so that makes sense. Interesting that doesn't label the central star.

At 2349 the sky meter reading is 18.41 and it is 77 F and 92% humidity. Shutting down for the night having achieved my goal of viewing the Herschel 400 objects in Vulpecula.

July 30, 2017
A front blew through yesterday and we had beautiful blue skies and tonight they are nice and clear. There is a half moon high in the S, but the skies are free of clouds. At 2148 it is 83 F and 58% humidity. First time out in a long time. Setup the ASI071MC-COOL at prime focus again with the Lumicon DS filter. Aligned on Arcturus and then setup to work on the Herschel 400, starting in Scorpius and Sagittarius

H 10-6, NGC 6144
The target was just off screen to the SW. I was able to center the object for observation, but I'm going to need to adjust the model before I move to other objects. This object is 29,000 ly from the sun, magnitude 9.0 v, and is 7.4 arcmin in size.  It is a densely populated GC in a moderately populated star field. The field is void of any significantly larger / brighter stars. The GC core reveals many discrete stars. There is a pattern resembling a Fleur de lis with the orientation N.

I did an alignment on Kaus Austraslis and tweaked the focus with the Bahtinov mask and the SharpCap focus assist routine.

H 13-6, NGC 6451
A cluster of over 2 dozen stars, most similarly sized & brightness. The shape is ill defined but I see a V pointing E with an appendage off the N circling to the E, terminating in a 3 star line with a fourth star to the NE over the center star in the line. The star field is very densely populated with a faint red nebulosity in the background to the W through the NNE.

Had to exclude image # 2 as a satellite flew through.

H 150-1, NGC 6440
A small (4') GC in a dense star field, but with some dark lanes to the NE (dark nebula?). The GC stars look red orange compared to the white surrounding stars. The GC has a large bright star to the SE about 10' from the center of the GC. There is another larger bright star to the WNE about 15' from the GC center.  Even at 30 sec the inner core in a line running NNE by SSW is blown out so I'll just stick with my 60 sec exposures as to capture more fainter stars.

Here is a crop of the above image.

H 586-2, NGC 6445
This object is only about 20' from NGC 6440 and I got them both in frame. The small (~ 1') nebula is surprisingly a rectangular shape rather than round. There is some reddish color around the edges but it is mostly white. It is hollow in the center. The star field is densely populated with one star that is much larger and brighter than the others about 15' to the SE.

At midnight the sky meter reading was 18.81 and the temp is 73 F with 82% humidity. There are some high thin clouds to the East. It was supposed to be clear tonight!

H 31-7, NGC 6583
A small cluster in a very dense star field. The cluster is rectangular in shape running NE to SW. To the W are 3 larger / brighter stars in a line oriented NW to the S about 3' from the cluster center. Within the cluster there is an line of 6 stars arcing to the NE and then E. In the FOV to the NE is a brighter star( the brightest in the FOV) and about 12' from the cluster's center. The star is bounded by 4 bright stars; 2 to the S and 2 to the E. There is a 5' line of 4 stars running NE from the bright star with the last 2 being within 1' of each other.
