AstroPixel Processor to stack
PxInsight to process

I tried to image the Jellyfish nebula in 2021 but could never get more than a faint glimpse of the "cap." In narrowband, it jumps right out. This is from just about 4 hours of data from one night of imaging. I'm not used to dealing with such detailed structure so I processed it as best as I can but am open to any advice, tips, or pointers. The red nebula up top is part of the same structure and is designed IC444. The nebula itself is IC443.
