Horsehead Nebula and Orion Nebula (PixInsight trial)
Stack of 25 shots at 200mm focal length and F5.6
10 x 120s RGB @ 1000ISO
15 x 180s with IR645 filter @ 4000ISO.
D810A + Sigma 120-300mm F2.8 + NEQ6
Shooting conditions were dry and dusty on the ground, very clear dark skies, a bit of wind and mild to no seeing.
This time I have done the preprocessing and editing with PixInsight 1.8, using one of many great tutorials out there. Final editing done with DxO OpticsPro 11, I might have "pushed" a bit too much and brought the noise and some dark issues out ...
If I have the patience tomorrow, I'll repeat the operation with a mosaic I shot of Orion a few nights after this photo. The conditions were not as good and Orion was getting close to Christchurch's light halo, so yeah ... annoying editing ahead ... it might take a while before you see said mosaic ... ;-)
