Description

2 nights during an (almost) full moon with an Optolong L-Enhance filter and an Askar 180mm lens shot with an Zwo ASI 183 MC Pro. Still kind of unhappy with the "blotchy" chrominance noise in the background, but maybe just need to add a few more nights.
Used the AZ-GTI now for the 2. time, familiar with guiding settings now, works after adding a little bit of grease like a charm, RA error of 0.8-1.5".

Bicolor image, HOO, with Red = Ha, Green= Oiii*.8+Ha*.2" and Blue = Oiii*.85+Ha*.15.
