Fish Head Nebula with Pixinsight by Tim Connolly

Goodbye Photoshop! Today was the first day I used Pixinsight. After spending the last few days watching tutorials and reading guides, I gave it a shot with Fish Head Nebula (IC1795), at the bottom of the Heart Nebula, in the constellation Cassiopeia. At first, Pixinsight appeared very foreign to me and overwhelming, but I started figuring out the different features through trial and error. I still have much to learn, but I am more than satisfied with the software. I used Image Integration and Image Calibration to register and stack the images. I then used LRGB to combine the channels and produce the Hubble Palette mapping the Sulfur II channel to Red, Hydrogen Alpha channel to Green and Oxygen III channel to Blue. I then went through and tried different processing with the curves, histogram and background processes. I really found the masks to be easy to use and found different methods to make the masks. I’m going to redo my previous narrowband images of Elephant Trunk Nebula, Cygnus Wall and Wizard Nebula with Pixinsight.
