Good job considering all... amazing what you can get in 15 seconds.
Do you using binning to increase the sensitivity of the camera? I don't know if the 2000xcm has binning modes other than 1x1, but if it does that might help you get more data without increasing exposure time.
Alignment and autoguiding both on their own take a bit to get right and working well for you, so you've got a good sized learning curve ahead.. Enjoy
