It just tickles my wife and I to be able to observe in moon glow. As I have said (but a very long time ago when this forum was in its infancy), using astro video essentially doubles your potential observing periods. We were pleasantly reminded of this on August 13th. The moon (four days past full) was already over 30% above the horizon...and we dared go for the Trifid to enjoy its color and (hopefully) some reasonable definition of its features. We were not disappointed.

 

The latest post in the blog (address under my signature) has the story and the sketch. (No...we don't do photography or mess with stacking...we study the object on the monitor and sketch it.) There is religious content in the story.

 

The sketch is a pretty decent representation of what we could see. I left out minor stars and about 1/3 of the fainter stars were washed out. But considering the sky moon glow, it was another night to remember that astro video really does expand the definition of when one can observe. I did try (just for grins) to go to a longer integration, but the combined moon glow and star field surpassed the limit of the camera to handle the scene (it went blank), so we went back to 14 seconds, which was more than ample (with Hyperstar) to get a nice display of the object.

 

Nope. The camera is not for sale.    :)

Hemmi, you are in NC. Are you coming to ECVAR? It is great fun. Sep 22-28 I think. Lots of astro-video "nerds" as well as a good time observing.

Nice sketches, I didn't realize you did them. Also these can be instructive for those that are doing visual only sketches of deep sky objects.

Absolutely. It is really the same process. My sketching colleagues think it must be really easy using astro video rather than eyepieces to sketch, but it is actually much harder because you have 10 fold the detail and color. However, visual setup sketching delivers one wallop of a neck or body ache whereas astro video does not. I will take that advantage any day.
