This is one of a series of pictures that I took using my 1980 vintage Meade 2080 LX just having some fun. I found that with 10 second exposures I was getting about 80% useable frames, which isn’t too bad! The drift between frames was a nice source of natural dithering which really helped smoothing things out. To keep things extra simple I just used an interval timer to take the source images.
