Description

Haven't posted for quite awhile - lot of catching up to do. I have been gathering but not processing so I have about years worth of data to organize and piece together. Here is the first:

Abell 2634 - NGC 7726, 7720 et all group of galaxies in Pegasus. Group is about 350-375 ly distant. N7726 is 14 mag, N7720 is 12.4 mag for reference. I combined a darker image with a stretched version to pull out the IFN in the area.

96 x 600 Lum 1x1
10 x 600 each RGB 1x1

Original image and stretched B image are combined to make the GIF in the final C image.
