NGC 7000

This is the object that got me hooked on astrophotography. Well, sort of. I started a long time ago with a Pentax 35mm film camera and a CG5 mount and tried to take a picture of Cygnus. It was horribly underexposed, but one of the frames had just enough exposure to make out the North …

Leo Triplet, Luminance Mosaic Test

This was shortly after (I think) some work to improve the collimation on the Ritchey-Chretien. I don’t know why I didn’t concentrate on a single target, but I jumped around from several last March, so once again I have mediocre data on all. Object M65, M66, NGC 3628 Camera ASI1600MM-Pro, Luminance Only Lens/Scope AstroTech RC6 …

Choices, choices, choices (in imaging processing)

One of the wonderful problems that has become more apparent with digital imaging with modern optics is high quality images with lots of stars. Back the dark(room) ages with film, it seemed that most images didn’t really pick up that many of the fainter stars. I can make up some really smart sounding reason for …
