Last week I went to my observatory and took the GSO 200/800 first light. I caught some high clouds but between them I manage to get 70min of lights. I forgot to lower the ISO from 1600 to 800, hence the noise. Anyway I am pleased with the result. NGC7635 / M52 - 14x300s GSO 200/800, LXD75, Canon 350d (MOD), Baader MPCC, Astronomik CLS Clip + IR Cut. Guided with Meade DSI and 50mm finder. Only darks. I am getting a darker band on the lower part of the image, does anyone know what can be causing this? I can't remove it with flats. I will have to catch this one again, next time with a lower ISO and more lights.
