Description

Another attempt at imaging and processing NGC 1499, with much more data than the last time. Definitely an improvement in the nebulosity, but the stars are terrible. I've been noticing this even in most recent captures, and I'm pretty sure it's not my focus or tracking/guiding issues now. I have a sneaky suspicion that my camera lens is out of collimation, and I'm getting comet-shaped coma even in the center of the frame. Whatever is going on, BXT does a decent job in correcting in, but not entirely, and some of the bigger stars end up looking a bit weird.
