M83

Hi Guy's

I took this a few months ago and decided to reprocess and see If I could get a bit more out of It.
Exposure time was 60sec x 35, shot through a C11 and a SXV-H9C on a G11 mount in mag4 skies .
Anyway here It is and of cause all advise and comments are most welcome !

Cheers

Hi Louie,

Basically it is very nice. I think though it needs much longer exposures.

I have been told by Sbig that for their one shot colour cameras it is best to have longer exposures like 3 x 30 minutes. It makes sense as the chip has the RGGB filter over it so each exposure kind of has to be 4X the length of a mono camera to get a similar result. You also have to get past the read noise of the electronics which in your camera's case is probably very low but still there.

Why don't you make sure your mount is well drift aligned and then try a 15 or 30 minute exposure and see if that is better than a stack of shorter images?

Best,

Greg.
