Description

This picture just "happened" to me.. As we do not have so many clear nights here I have decided to take out my equipment even few days before the full moon. The sky was absolutely clear and big moon was shining like it was a day. I was thinking to wait till late night when the moon will not be that high on the sky. But as I did not want to lose even a minute of the clear night I just randomly pointed to M3 and (somehow atomatically) turned on my canon (thinking that a bit later will try imaging Iris nebula)...

Started to read my book and.......woke up at 4am next day :-DDD My scope was already out of my FOV taking the pictures of my house ))) Even being a bit out of focus, I have decided to stack best 29 frames and post them here.

The final image is a bit out of focus but as I said - this picture just happened to me))))

p.s. after I woke up it was ofcourse too late for Iris nebula..so maybe next time?)))
