Hi all,
This is my first attempt at NGC 6188 and my first go at HaRGB from the Bortle 7 skies of my backyard here in Sydney.
I have also attached the starless Ha that I used to blend the image.
Ha: 34 x 5 min, Astronomik 12nm Ha filter.
RGB: 30 x 4 min. Optolong L-Pro LP broadband filter.
Camera: ZWO ASI2600MC Gain 100 -10degC
Telescope: AstroTech 65mm EDQ
Despite the use of the L-Pro filter and flats there were heaps of gradients that needed removing in the OSC data making it a bit of a challenge to process.
It looks like it might be awhile until my next dark-sky trip so I need to make the most of what I can do with the conditions I have.

Astrobin.
