NGC 2683
NGC 2683
Last night I tried out my new Nikon D750. It is supposed to have really good low light, low noise capability - besides being a really great camera for family, etc. So I took 30 exposures of NGC 2683. I did some simple processing in Images Plus. The attached photo is a fairly wide field view of NGC 2683

Re: NGC 2683
Roger, Congratulations on the new camera! How long were the sub-exposures, the sensitivity and low noise seems quite good?
When I zoomed in to the full resolution image to see the galaxy better I noticed you are getting some star trailing. At the risk of providing unsolicited advice... this could be fixed by guiding as it is a result of the ordinary periodic error in the RA drive.

The images were 120 sec subs... you are correct in seeing the trailing star images. I plan on using my autoguider once I am comfortable with focusing and camera control. My next step will be to connect the D750 to my CPC1100 (with focal reducer), and then use Lodestar attached to the Steallarvue 90mm for autoguiding. That will be a big step for me. I have tried out all of the
'pieces' but have never attempted to put it all together.
