This is sort of dark nebula/light blue nebula in the middle. The FoV is 4x3 degrees. The colour is down to the filter used, an old 2007 Revelation IR filter that I'd grabbed for testing purposes. This has meant no Ha made it to the camera :{.
This is 60 x120s subs on an unguided ZWO AM3 mount polar aligned using PHD2 Polar Drift alignment which is so easy to do accurately it's amazing. Subs were captured using a Raspberry Pi 5 mini-computer using Indigo drivers and AIN imager program.
