Description

My first crack at M101 and first time using a clip-in Astronomix CLS filter. I wonder if I went a bit high with ISO12500 (300mm). Everything is quite blue, but the stretched histogram was at about 2/5 on the camera. It did show blue higher, red lower. But I honestly hadn't even noticed that info before. Anyway, it's there! Gotta remember this is still the barn door tracker so not too shabby.

Canon EOS Rebel SL2

300mm @ ISO12500

NOTE: I have since confirmed the CLS will cause the blue shift and you need longer exposures to get reds. Will take another crack at M101 sometime without CLS and with new gear that's on the way...
