It past long time since I took these photos but these days I can’t use my telescope and I have just a binocular that I use sometime when it doesn’t rain or snow or is not too cold, so I decided to review some of my work and process some pictures I missed.
Details: Newton Ziel Galaxy2 8′ on Skywatcher HEQ5 Syscan with camera SBIG ST-237. I took 49 images for luminance, and 20 images for each channels RGB. Every image has exposure of 20 sec at f/5, focal 1M. Shooted in Rome, on 20 and 22 July, 2009.
