Photo description / processing
First Light for my TS RC8 after some problems with bad collimation. The sky was only clear for a short time so I decided to capture just a minimum of frames for RGB to get a colour image but I could´nt capture any Luminance data. I also didnt use a field flattener to keep the original focal length of 1624mm.
