Hi all,
apologies for my absence - the non-stop rain has made it hard to feel enthused about astronomy but I managed to make some progress on my setup and finally captured some photons with it during that brief window of good weather last week.
Sometime back during the last few months of dismal weather, I acquired an Antila Dual-Band filter (Ha & OIII) which is obviously a competitor to filters like the L-Extreme. It's a bit more expensive but according to Antila it doesn't suffer from halos around bright stars and can work well with faster f-ratios.
This is my first attempt at a HOO image so the processing was a bit of a learning curve, but I'm pleased with what I was able to capture through Bortle 7 skies. I did plan on capturing some RGB too but the clouds arrived to kybosh that idea.
72 dithered 90 sec subs with a ZWO 2600MC captured in NINA through the MN190. I chose Eta Carinae as it's a nice bright target for a test image that was relatively high in the sky.

C & C welcome as always.
