Description

I had grand plans of getting this LRGB image done of Markarian's Chain as a running start into galaxy season. Learned a very valuable lesson.... Don't waste ones time trying to do good RGB under a moon.

I was able to get a fairly nice luminance image though, and thought I would publish it. the RGB image will have to wait until later in the month...

Edit 4/16/2019: I had posted this and was quite unhappy with the way it appeared when I published it. A lot of the detail did not appear that was visible to me in PI and when I saved it as a png file. So it was up on AstroBin for about 5-minutes and then I deleted it with the thought of waiting until I completed all the RGB and assembled a final image. But... it reappeared!!

So I guess I will leave it here and perhaps upload a revised image if I can get it to save such that the galaxy details that I can see appear in the png file.

CS to all!!
Mike

I added in all the RGB integrations and then extracted the luminance to update this. It seemed to quiet the noise quite a bit....
