This image is the result of my longest data collection yet.
Flaming Star and Tadpoles, Foraxx SHO palette with broadband stars.
This image also was also the result of an experiment in combing Oiii data from two separate dual narrowband filters, the SVBony SV220 Ha\Oiii and the Askar C2 Color Magic Sii/Oiii. I'd shot about 67 hours between the two, so I loaded everything up in SirilIC, selected that all sessions were Ha/Oiii and let the stack churn away, and discarded the combined Ha\Sii channel it extracted and was left with the combined Oiii data.
Also new during this image was a move from the SkyWatcher GTi to a Celestron AVX mount, and the addition of a ZWO EAF to my lens.
