Light Pollution Sucks
The Carina Nebula and Running Chicken Nebula from my Adelaide metro (Bortle 6) backyard. This is a combination of 13 stacked shots with a Optolong L-Pro filter and 1 shot with an Astronomik 12nm Ha filter as a luminance layer. Lots of issues, no lens collar meant I was getting trailing from differential flexure despite autoguiding. The light pollution meant even with the filter the blue channel was maxing out way too early. Horrible gradients over the frame (this is a crop). After huge amounts of adjustment the star colours are somewhat red. I will try the L-Pro again with a longer focal length (see if that stops the gradients) and will see if it helps when used without light pollution. Otherwise I am doing something very wrong here!
