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.
Ryan,
Great effort there and some good detail on a difficult target
Gee that’s a mammoth amount of data for a decent light bucket
Did you capture calibration frames as well ?
One observation, your stars still have that diamond shaped to them again, must be something in the f4 optical train ??
Well done !!

36hrs just meant I could be really selective with my subs. In the end 20hrs split over the Ha and O3 filters is only really like a 10hr image with my dual band so not that exteme. I feel it’s been worth it though. In the absence of a mono camera that is....
The diamond stars I introduced in my processing...... again. I tried cleaning them up a little in the end but I have to stop doing it.
