July 4 Observing Report
the hamburgers and hot dogs were consumed and darkness fell, Heather
and I slipped out to the observatory for a quick viewing session.
Heather discovered she only had 6 Messier objects left to observe and
they were the ones in Scorpius & Sagittarius we had looked at on
July 1 but she had neglected to log them. So on a hot, humid, but
clear night with decent seeing (no star twinkle and no planets
dancing in the eyepiece), we observed Messier 4, 6, 7, and 80. By 10:00 pm
Sagittarius was high enough for her to see Messier 69 & 70 at the
base of the “tea pot”, and she was done! We capped off the
evening by taking a quick look at M57 & M13, and then called it a
night. I checked the sky quality at 22:40 and got a reading of 18.78 mpsas or a limiting magnitude of 4.60 and a temperature of 81 F.
Congratulations to Heather for completing her observations of
the Messier objects!
