Description

This object culminates at 23 degrees at the location of my observatory, so it is hard to image.

Last night is was above 20 degrees elevation for almost 2 hours and it was a beautiful clear night as well. I acquired 3 x 600s L frames, and 3 x 600s R and B. The G channel was synthesized by adding R and B 50/50. I hope to collect some more data the coming night!

It took some more time than I expected, but I added real green now and also some more blue.
