NGC 7822 Hubble Palette

[Prolifics]

My first ever Narrow band image.

30 Minutes each of 5 minute exposures HA, O3 & S2 using Hubble Palette in Pixinsight. Gain I made a mistake should have been 200 but used 75 as I reloaded Nina and forgot to change it back from defaults

The 03 filter is giving me halo's on big stars. I need to find out how to fix this (Either by hardware or post processing). I have some elongated stars on 2 sides. Caused mainly by the 5 minute exposures. Tilt maybe an issue? Guiding was 0.53 RMS.

Great start to NB. I like the first image but I think you can up the saturation a bit to bring up more colour.

Second image is "Hulk Smash !", love it. looks really menacing and ominous.

Think theres a little less noise and some more colour.

That's much better.

That's a great first narrowband. Well done.
