Description

This has been a project I wanted to work on for a while now that I was finally able to collect data for. This is a 2 panel mosaic of the California Nebula in 2 channel narrowband. For whatever reason, I could not really get any significant OIII on this target, and I was also imaging near the moon, so eventually just decided to go with Hα and SII. The palette mix is a little unorthodox, but I wanted to get a Red/Green separation with yellow defining the common areas and that is essentially what I ended up with. After some frames were discarded I ended up with a little over 17 total hours of integration between the 2 panels. Stars were removed for processing with a small stack of RGB data being used to add them back in at the end of the post processing. Preprocessing was in Pixinsight, with post processing split between Pixinsight, Photoshop, and Lightroom.
