Subject: Re: [Astro_IIDC] gain vs frame rate

Thanks Alan, during this next week I am going to try some lunar imaging and hope that it is more tolerant of my inexperience and requires less expertise than Jupiter.

I have been viewing movies and reading all day and am a bit overloaded.  I am sure I just need to take more data and process more data to get a better grasp.  If you want to be a writer, you have to write.  I suppose the same is true for this art form (planetary imaging) as well.

On gain settings, I am very often working at levels above 900 in Astro IIDC. The DMK mono camera noise is quite manageable at these levels in my opinion. It really depends on the seeing and the subject whether it makes sense to drop to a lower frame rate and slower shutter setting to improve the signal in the individual frames.
