Crescent nebula in HA

[Kaliska]

About 3.5hrs of data here and my first venture in to narrow band. I have the OIII data to add (which I'm having some problems with atm), but still like the detailing in HA.

TSQ100, ASI 1600, 180sec exposures and a very quick stretch in PI.

Your first venture into NB? That is a truly excellent start.

Great image and a genius start. This is one of my first targets back a few years, but it took me a long time to figure out the OIII!

There is a beautiful shell around the nebulae, but its extremely hard to get especially that it needs to be detailed to really pop. I wish you luck!

Kind regards, Graem

Thanks for your all comments.

I've acquired about 2hrs of OIII so far, but i'm struggling with the calibration of all the files. The images look really good post calibration, but when I add my flats and darks, I'm getting a huge gradient. I'm out here again tonight getting the OIII, so hopefully I should get some better results.
