Bode's galaxy with ASI178MM

Postby NDB » Tue Feb 16, 2016 2:05 pm

2nd deep-sky test with the ASI178MM (still uncooled).
5-s exposures; the galaxy is poorly contrasted.
One dark for all images with SharpCap. No guiding, no bias, no cooling... no stress :)
Sorry for framing.
Suburban sky, just above the chimney (some frames were blurred and enlighted by the reflection of street lamps). Anyway the camera is fantastic, even in this very average conditions!

I don't think this is a great camera. It has a horizontal banding problem. Traces of this pattern are visible in your image.

There exists software to to reduce or eliminate this banding problem, but I think this problematic, because it can introduce additional image artefacts, which are difficult to detect. Dark frame subtraction alone will not help much to get good deep sky images with this camera.

Tom,
Have you experience with the 178MM on solar imaging??
(I currently use the ASI 174 and will add an ASI 183 for shorter focal lengths)

I've tried to use a 178MC for deep sky and planetary imaging and documented some of my findings at the "Banding issues with ASI 178MC" thread in the camera section.
