First go Carina nebula with basic tracking mount
Hi,
I borrowed a friends Celestron STL mount and had a go at the Eta Carina Nebula from suburban Melbourne. It was also my first attempt at using dark/bias/flat frames (only one of each). I used DSS and adjusted the image after stacking and then made a few more subtle changes in GIMP.
I am happy with the result, but I am not sure how far to push the settings, initially I had the colours looking overcooked and fake, then I had the centre washed out and over exposed.
Are there any rules of thumb when stretching levels or adjusting brightness/contrast and mixing RGB channels? I basically tried to get rid of the overall purple tint (and make the sky black) but still try to have the colours look like the original, but pop a bit more.
Canon 6D, Saxon ED80, 9 subs of 20 secs @ ISO 3200.
Advice/suggestions welcome. Thanks.
