Description

This image is taken from my backyard observatory (Skyshed POD) located in the white zone of Silicon Valley, California.
PuWe 1 is a large but very faint planetary nebula and it looks a lot of exposure time.
This image takes 21 hours of Ha data (3nm) and 16 hours of O3 data (also 3nm).  Several hours of RGB for star colors.

Process with PI.
RBG --> ABE --> ChannelCombine --> ABE
Ha + O3 + RGB --> NBRGBCombine --> DBE --> BTX --> Stretch* --> NTX* (*loop)

Comparing to other CMOS images, I felt my old 8300 is not sensitive enough on this task. ;-(

This nebula was found in 1980 -- https://articles.adsabs.harvard.edu//full/1980A%26A....87L...5P/L000005.000.html
