When I started imaging the Pelican Nebula in August of 2022, my original intention was to do a SHO image. Unfortunately, I only captured Ha and OIII data with the SX694M before the clouds moved in for about a month. Right before the clear skies returned, I received my QHY600M and swapped over to using it full-time. Over the winter, I processed the Ha and OIII data I had on Pelican to make the HOO version (Revision A) and considered moving on. But I hate not finishing what I started, so 10+ months after I first captured data on Pelican, I reattached the SX694M to the SVX080T-3SV and gathered the rest of the data to make a SHO image (Final Revision) with RGB stars.
As soon as I combined the SII, Ha, and OIII data in Pixinsight, I remembered why I'd been dragging my feet on finishing this project. Processing SHO images with my SX694M imaging train is a struggle since my SII and OIII filters are 3nm bandpass and my Ha is 5nm. The Ha signal overpowers the other two filters, and it is a battle to control the green while somewhat staying close to the Hubble palette. After multiple failed attempts, I settled on this close enough approximation
