Thor's Helmet is another target that I've been itching to get back to image. It was the last target i Imaged at the end of 2019, when I went on hiatus, due to life/weather/work reasons.
This is just under 3 hours of Ha and just under 4 hours of OIII, combined with RGB stars. Full Equipment and Integration time is on the
Astrobin Page.
I processed the stars separately, and used Pixel math on the Narrowband channels, for a HOO mix. The severe lack of clear skits this summer has felt incredibly limiting, So while I would love to collect more data on this object (including SII data), I think that's where I'll leave this guy for now, at least until I have some more clear nights up my sleeve.
I've also included a closeup of my previous attempt from 2019. I wish i could tell you how much integration time went into that...
As always, C&C is very welcome.
Enjoy, Thanks for looking and Clear Skies!
