This seems like a good time of year to try M31 and I have put together a small kit to attempt image capture. Using a Nikon D7200, with a 70-300mm zoom mounted on a iOptron SkyGuider Pro. I have managed to capture M31 but need to work on the tracking, as I am only getting 45 sec per image right now. Not sure if that is long enough and even then only collecting just over an hours worth of images.
Using DSS to stack and have PS CC for final processing. I can 'see' M31, but the it is weak and not sure what it should look like before processing. Have seen all of the great images on here and elsewhere but not really sure what I should be expecting from a single image before DSS and then the composite image out of DSS and before PS CC.
Any advice or links to videos would be appreciated. I found a couple of videos but cannot find them now that seemed pretty good. So much out there and yet some of it is a little brief and hoping to find a little more detailed videos to watch over and over (will need to remember to save a bookmark once I find one that I think is good).
Thanks in advance, as I know you guys see these questions all of the time.
