Hi,
Could anyone give me any pointers on why I'm getting the large scale and small scale noise in this image (& how to improve it)?
I'm guessing the large scale noise is light-pollution, but the small scale noise appeared after stacking in each individual channel. Cant seem to remove either sufficiently well with DBE.
Using an Atik Horizon Mono, LRGB filters, Bortle 6 zone.
Any help / tips on what to look into really appreciated - I've been following the pixinsight tutorials for RGB pre-processing (inc. subframe selection and drizzle integ etc). I've attached RGB combination & zoom plus the small-scale noise shown in green integration.
Cheers
