I have a Celestron CPC 11" f10 telescope and i use Nebulosity to capture my images and i use Orion Autoguider. I have a f6.3; f3.3; and a 5X focal reducers. I know i can't use the f3.3 focal reducer because it is for smaller chip cameras. I don't know about the 5X focal reducer. I bought the ZWO ASI 1600MC Pro. Could somebody explain the settings to me ? like which settings is best for DSO's. High Dynamic, Unity Gain , low noise, or set the gain to a specific number. What is the usual or customary settings so i don't have to waste several nights testing on DSO's?
Thanks for any help.
