Observing report : 06-30-2008
With a clear night and a forecast for low humidity (they lied), I decided to take a tour of Scorpius.
My first target was M4. The seeing was average or slightly below. Viewed at 48X, the cluster was very faint. I popped in the Barlow and got better definition.
From there, I moved to the binocular triple for a starting point in my search for M80. M80 was almost a carbon copy of M4 in my seeing conditions. Again, I started at 48X and used averted vision to get the full impact. Moving back to 96X, M80 seemed to just pop out better than M4.
I noticed that the Teapot had moved out from behind the house next door, and pushed the scope over to it.
First target in the teapot, M28. I know that the magnitude for M28, M4 and M80 are almost the same, but M28 seemed much better defined at both 48X and 96X. (Perhaps I had my full night vision)
From M28, a quick swing to the east brought me to M22. Not sure of M22’s magnitude, but the best definition so far. Just a wonderful sight.
Now I got ambitious. I live on the north end of a town of about 20,000. So all of the light pollution was between me and my goal. The Trifid nebula. I couldn’t get enough guide stars to find it. I kept running across more clusters, but I couldn’t identify them. Could have been M8, M20 or M21. I guess I’ll have to wait for a dark sky site.
Looking back toward Scorpius, I could now see all of it. I couldn’t make out my guide star with the naked eye, but the Jewel Box is bright enough that I could the lower cluster in the guide scope. The best of the night by far! A beautiful tight cluster just under a very loose cluster.
I finally finished my night with a 5 minute viewing of Jupiter. I last viewed on Friday night. I love watching how the moons change position.
Packed it up for the night as dew was becoming a problem. Lying weather man said low humidity. Checked on the weather channel web sight at midnight. 74%!
