High praise - wow, thanks Steve.

I was very happy with the detail the scope was picking up. Part of that is the good seeing I was having.

Thanks for that. A surprising amount of detail did come out.

Cheers Paul. The 17 does pick up those little background galaxies very well.Too bad its so large and heavy or I'd take it to my dark site observatory for an imaging run.

Cheers Jeff. It does go through quite an amazing transformation to get to the final image. I spent about a week on the processing and various versions until I got to the point where I thought - thats it, its not going to improve from here.

But whats giving the unusual spike (diffraction?) on bright stars?
CDK has secondary vanes. Funnily enough it tends not to give diffraction spikes unless the stars are quite bright. Also the Proline tends to give a little diagonal spike on some stars. My Microline doesn't so that only the Proline. Some little quirk there.

Thanks Alan. I've always liked this galaxy and its an unsual looking one with not many deep exposure examples around.

Thanks Greg! It was a lot of work but I am happy with the final result.

Is that swirling gas above the galaxy something that is not usually seen?

Did you need to use noise reduction at all?

Yeh, I see a touch of the Gabany look too

Mike
2 days? Naah more like 2-3 months. The observatory of course makes it possible. I'd simply set it up, frame it, click start and close everything up next morning. Minimal noise reduction, I am not a big fan of that either and is another reason why I want to do mega exposure imaging so the signal is strong enough to take the processing without too much noise.

I have another galaxy image that is 27 hours from about 35 hours worth which was a better survival rate of data.
