IC405 and IC410 in HsOhO as I had the opportunity to add SII and more OIII.
Processed without Tonemapping, it was worth the extra effort despite overall low integration time.
This is part of a multi-year project as next summer I'll add more frames (I target 20h+ per channel)

There are a lot of Ha around the two ICs that are discernable but would benefit from more integration.
O3 is rather strong and large in IC410 whereas in IC405 it is packed in a much smaller area in and is significantly weaker.
S2 is diffuse but follows Ha distribution.

I'm rather happy with the colors especially for O3 and given the overall limited integration time under SQM18.37 sky :)
