This is M13 shot through my C-8. The exposure was 15 min. on Kodak Royal Gold 1000 film and a Minolta camera. I had trouble finding a guide star through my OAG, so the guiding was not that great. I am going to switch to a guide scope, so next time it should be better. The image was scanned and 2 layers were combined in Adobe Photoshop using the Overlay mode.
