NGC6188 - first narrowband
Not many targets suited to narrowband available in my limited field of view at home this time of year, but I have been wanting to try this one. Only used Ha (9x5mins) and OIII (10x5mins), because as I started collecting RGB it was around meridian and decided to pack it in.
Blend is Ha:OIII:OIII. I know it's very red/blue. I did play with a synthetic green from Ha for red and OIII for blue, but wasn't happy with the colours. So many variables with this NB imaging.
Any tips on processing greatly appreciated.
