Here is a 26 X 600 second stack of M33 consisting of 8 Luminance and 6 each Red, Green, and Blue taken through an A-P 180 EDT with a STXL16200 camera. I am still on a learning curve with regard to processing, and for this one I used Digital Development for the first time.
Nicely done. Cropping off the bottom and right side would be nice finishing touches. A lot of detail in there, really nice.
Thanks Colin. I thought about the cropping after I had already posted it. Here is a cropped version. Merry Christmas to everyone at Diffraction Limited.
