Thor’s helmet
Hi all,
This is one of my favorite nebulae.
I’ve been working on this one since late December waiting on the right combination of clear skies and no moon. It’s my first attempt at using narrowband filters with a OSC camera ( ZWO071mc ). It certainly worked well but the capture time was a blowout compared to what I’m used to with my dual band filter.
In total I imaged over 36hrs. The 6hrs of SII was pointless but interestingly the subs had terrible FWHMs and huge reflections. It was ok for this object but disappointing that SHO imaging may still be out of my reach with this filter set. I was however happy with the O3 and Ha filters. I was quite aggressive with my sub selection so the final image is the 20 best hours split between each filter to produce a HOO image.
Comments and critique welcome
Thanks for looking
Ryan
