Eta Carina.
Preprocessing in Pixinsight, thought I would try my hand at post processing in StarTools, which has meant a new learning curve.
I am satisfied with the result, but I'm sure that Ivo would do much better, and I am happy to upload the cropped .fit file out of interest.
I did have a little trouble with colour saturation which improved with the application of a full mask. But it's not quite what I was after.
Cooled 1000D @7C - Astrodon Inside filter, 200mm, F/6.3, iso400, 25 x 3.5 minute subs, with bias, darks and flats.
I wanted to replace the stars. Get rid of the spikes and replace with spikeless ones, but came unstuck with that and gave up?
Synth > Refractor > 200mm (should I add the crop factor), aperture 72mm, after that, no idea
Thanks for looking
