Description

M3 Globular Cluster.... Familiar to most. Learning more about channel combination with this project. I think I may have made a step forward in that regard.

I did have some difficulty with gradients in this image. I have a neighbor, who is about 200m from my work station who has a one million watt yard light (lol) on a motion sensor that is causing me problems when it shines directly on my equipment. I had to do the luminence integration set 3-times to cull 60 good frames from the sets.

I opted to play with this a good bit in the staging area before publishing it. There is a full size image (not cropped) that I like as well but I had to make a decision between the two.

Comments and criticism welcome as always!

CS,

Mike

Description: completely reprocessed using recently learned techniques. I went with the full crop on this because I really like the little spiral galaxy at the top right. That's it for this one until next year, maybe...
