Description

M42

Processing Chain:
  1. Stacking by Seestar S50 internal software to FITS file
  2. Automatic blackpoint/stretch/noise/chroma filtering by AstroSmartProc (ASP) DIY software
  3. Manual highlight mapping/brightness/contrast/RGB adjustment in  ASP

Note: this image is not as 'pretty' as that produced by an earlier version of ASP, but is closer to the light data as received.

Frames: 15 x 10"
Integration: 02'30"

Longer exposures (i.e., > 02'30") will produce better results - rare clear skies permitting...
