Pretty
clear night, setup at 2030. Temp is 82 F with 58% humidity, although
after setting up I'm sweating like crazy, so it fields more humid
than it is. Very few clouds and a very light breeze. Mosquitoes are
thick but I've got my Thermocells
out and I have Deep Woods OFF all over my exposed skin. Hope the
sweat doesn't wash it off!! I set up the mount in the house the
other night and it checked out pretty tight. (Parish mosquitoe
spraying truck just passed. Glad I'm in the tent.)
I
haven't had the scope out since Aug. 1 due to persistent clouds and
rain. Glad to finally have a clear night and tomorrow night is to be
nice as well before it rains late Sunday. This could be my last
observing session before my Mallincam arrives !!!
At
2137 I finally got everything setup and the scope aligned on Vega and
Algenib. It was just out on Algenib, so hopefully it will yield good
go tos tonight. Using Astroplanner on the iPad to choose objects.
M29
in Cygnus is a nice open cluster with a group of 3 stars and a group
of 5 stars in a distorted square. The stars in the group are not
appreciably brighter than those in the surrounding area.
Went
to M27, the Dumbell Nebula. Couldn't see anything so set the scope
up in high precision mode and aligned on Alberio and with the B18
(Barlowed 18 mm EP) the Dumbell came right into view, just to the
1400 positon of center. Couldn't see it directly even after staring
for a few minutes but with averted vision (AV) I could see a dense
squarish grey cloud. The Mallincam will make these much more
enjoyable!
It
is 2306 and it is still 81 deg with 62% humidity. Very few clouds
except high thin ones. A nice night except for the heat and
mosquitoes, but the Thermacell, spray, and Deet are keeping them
away.
At
mag 8.4, M 71 is a very faint globular in Sagita that is difficult to
see even with AV. I'm using the laptop to control the scope and I
don't see how to use high precision mode via the computer. Need to
study a bit.
NGC
6830 is an open cluster in Vulpecula. At mag 7.9 it is faint but has
2 bright stars at 4 fainter ones to the NE in the B18. With AV I can
get a peek at a deeper star field.
M56
is a GC in Lyra at mag 8.4. In the B18 I can just make out a faint
grey fuzzy. Could be a nebula as even with AV I can not make out
anything except an area that is slighlty brighter than the
background.
NGC
6819, Fox Head cluster, in Cygnus is mag 7.3. I see 3 semi-bright
stars and with AV a hint that there is more.
The
Ring Nebula, M 57, is a nice sight in the B18, with AV I can detect
the donught shape.
M39
is a very nice and bright OC in Cygnus with over a dozen bright
stars. The shape is roughly that of a robot with 4 stars in a line
across the bottom, 2 at the waist and a head. Shoulders and arms can
be made out. A nice OC, easy to see in the B18
M30
is a nice faint GC in Capricornus at Mag 6.9. It is rather low but a
nice sight with AV although I had to really contort my body to see in
the EP.
The
Andromeda galaxy, M31, is a nice sight in the B18. I can make out a
wispy near circular shape of almost uniform brightness. Cannot
really discern the core or the arms, but a nice sight. Easy to see
and appreciate as a galaxy. Perhaps my best view of it. With the
B6.7 I can get a hint of the eleptical shape but no details. I'm
impressed I can B the 6.7, good skies tonight. It is 0106 and 78 F
with 79% humidity.
With
the high precision mode the gotos are very good. Uranus is a nice
blue-green disc in the B18. In the B6.7 it is a bit more white and
slightly deformed. The 6.7 alone provided a nice view similar to the
B18, perhaps a bit less color.
Neptune
is a bit smaller than Uranus and the color was just a bluish off
white. The color was not as distinctive as Uranus. Hard to discern
but its lacking of twinkling and a comparison of the star field
against SkyWalk, convinced me I had seen it in the B18. In the B6.7
it is a distorted little disk with no color .
Very
nice view of Jupiter and 3 moons in the B6.7. I can easily see 2
equatorial bands. The image wasn't quite steady enough to discern a
third band. It is 0215 and Jupiter is around 40 deg up in the E sky.
The
Pleadies (M45) is a beautiful sight in the 18 EP. In the B18 you
have to scroll around to see the entire group, but many interesting
asterisms are noted.
Orion
is rising and the great nebula (M42) is a very nice site in the B18.
The 4 stars of the Trapezium are easily seen as are tendrils of
nebulosity. In the B6.7 the Trapezium is in excellent view and the
nebulosity extent can be well seen.
Very
nice star field in Persus near Mirfak. Up by Algol, M34 is a really
nice OC with over a dozen bright stars. Too tired to describe the
shape, but it is nice (It is 0331 !!!).
Last
object of the night was NGC 0475, the ET OC. He is standing on his
head at this hour but is a nice object in the 18 mm EP. OK @ 0346
I'm shutting down. A good night.
The scope performed
well but I did notice that the scope still has a shudder in its
movement at times. Need to investigate and fix that. Also the
focuser motor slips occasionally.
