Very very nice Tom. Tell us your secrets to reduce noiseUlteriorModem wrote: ↑Sun Apr 05, 2020 11:36 pm I had kind of promised to re-visit this data. The data is quite good and was able to get results from it.
Managed to stifle the low scale noise and still keep a lot of the nebulosity of the galaxy visible. Had a little fun with the color too
I use pixinsight careful use of range mask + star mask (in pixel math) to create a mask that covers the stars and hopefully most of the object. Then hammer at it with MLT.Mac wrote: ↑Sun Apr 05, 2020 11:54 pmVery very nice Tom.

Getting the mask right is the trickiest part. Lots of trial and error there because every set of data is different
