SBIG STX Image - NGC 2237 (Rosette Nebula)

[Octane (Humayun)]

Could that be a column defect (or, would that effect the entire column?) rather than a satellite? It's in a couple of other images that I noticed as well.

What's the chances of getting a satellite trail which is perfectly straight in an image?

Anyway, it doesn't detract from the image, at all; just an observation.

Column defects would be removed by dark frames, and if dithering was used when stacking, data rejection algorithms would have removed them too...

A most awe-inspiring view. Thanks for "showing us how its done" Martin. Just amazing being able to scroll around inside all the beautiful detail.

Wow that is incredible. Never seen it like that and as Hamayun said I also did not realise the extent of of this neb.
Nice work Martin.

Cheers Daniel.

Thank you very much all.

The artefact you have found is neither a column defect or a satellite trail. When I was beta-testing I was using beta drivers for CCDSOFT, Maxim, CCDOPS - trying them all. What you see is the result of a bug in the CCDSOFT driver, which kept the shutter open during the download. I took many frames with CCDSOFT in many images, and some were effectively removed through dithering etc, but I also had to manually clone out dozens....I clearly missed this one.

I reported that bug, so hopefully it is now fixed.

cheers

Awesome shot. Incredible to see the extent of the trails. A new perspective on a familiar DSO. Top work.
