To be fair, with what I'm producing at the moment, I'd be extatic about either image.  |
Ryan, all narrowband acquistion requires longer subs, regardless of the camera used, because it is only allowing a thin slice of the spectrum through the filter, and in many cases there is not a lot of signal coming from the target, so time on target becomes important. When I shoot pure narrowband with my mono cooled camera I use 5 min subs as default.
Chris that Duo shot looks ok but the star colour needs work. I don't know anything about PI but I could fix it in Photoshop.
To be clear, i am only asking about the Duo for my Nikon D5300, i am very happy with the narrowband performance of the ASI1600MM-C; but the Nikon has a larger sensor that takes advantage of my wide field scope larger image circle.
