I did a bit of experimenting with lucky imaging. Layer 1: 90% of the best frames out of 7,811 (about 7,000) at 1 second each at maximum gain. Processed in AutoStakkert!, resampled 2x, deconvolution in Registax. Layer 2: color data from the previous image in "Merge" mode in GIMP with transparency around 30–40%. Layer 3: same as Layer 2, but in "HSL Color" mode. The atmosphere wasn’t very cooperative, and guiding was terrible for most of the night—still not sure what the issue is, maybe something with the guide mount or the mount itself.
