NGC 253 Comparison
Again, feel free to post (or repost) your 253's.
Attached is 2 images from the same data set.
300 of 30 sec. (Next time I will try 60 sec.)
Gain setting of 288. (Next time I will reduce that to 150.)
The first image is un cropped and basic post processing ie:
Background Neutralisation, SCNR (remove green), Colour Calibration and then a Histogram Stretch.
It reveals a very bad SNR (Signal to Noise Ratio) and there is no colour.
Probably because of my settings (above).
The secound image (same data):
Not a single pixel was left standing...
I threw at it every PI processing tool that would do something to help.
It certainly pays to get things right at the start :-(
