OSC (Vespera V2) - Blending Ha/OIII & SII/OIII

#1

Post by brenski »

I've just ordered a couple of filters:
• Askar 2" Colour Magic C1 (Ha/OIII) and C2 (SII/OIII) Duo Band Filter Set

I'm intending to use these filters with the Vespera V-2 to produce two different stacked tiff files.
Does anyone know of a PShop or Siril walkthrough for processing the pair together/blending to produce a blended image displaying the pinks/reds/yellows and blues as one final image?

Hi,

sorry, I don't have anything useful on tutorials/walkthroughs on that. I suspect that both pieces of software will have functionality to split a colour image into the 3 colour channels and to do the reverse (merge 3 colour channels back into an image), but the details will be software specific.

cheers,

Robin

Thera are a few tutorials on YouTube (e.g. Cuiv the lazy geek) for using and processing (mostly using PixInsight) C1/C2 or D1/D2 image data collected using an OSC.
Cheers, Chris.

Recent versions of Siril have some really good "python scripts" as well as native Siril scripts that can handle many narrow band scenarios - and there are Many additional scripts available, directly from links at Siril's website or do a web search.. I only installed a few and many were stock with the Siril install dowload best as I remember.
