Description

I imaged this in a bit of a strange way... While waiting for my new iOptron mount to arrive, I had some good seeing and decided to image M15 with my Dobsonian telescope. I took 450 exposures, each only 80 milliseconds, and stacked them. No tracking, no coma correcter.... so there is a lot of room for improvement. There is apparent banding from the read noise which I tried to eliminate, but for such short sub-exposures I'm impressed with the results. The total integration time is only 36 seconds, so I'm surprised that so many stars actually showed up like they did.
