Finished image at last.

Object: NGC 1365

Object Info:
NGC 1365, also known as the Great Barred Spiral Galaxy, is a barred spiral galaxy about 56 million light-years away in the constellation Fornax. The core is an oval shape with an apparent size of about 50? × 40?. The spiral arms extend in a wide curve north and south from the ends of the east-west bar and form an almost ring like Z-shaped halo. The central mass in an active galactic nucleus rotates close to relativistic limit (the dimensionless spin parameter is larger than 0.84).

Geesuz mate, look at you go. I love the fact that you have caught the outer parts of those spiral arms (very hard to get). I imagine you have some decent skies? Well done buddy, that's a cracker.

Thanks Ray, I intend on doing a repro at some point to try remove the background noise.

Did a repro but not sure if I'm happy with it. Definately improved noise in background but lost some colour.

Wow much better mate. Have a play with deconvolution if you haven't already.

I actually preferred the colour and detail in first one Ray, even with the noise. Overall I wasn't happy yet and after some advice from others on IIS forum did, what I'll call at this point final repro.

This last edit really shows the starburst regions. The noise is perfect as well. I'm jealous of your skies brother!

don't think my skies are that great mate, i live on the edge of the main light bubble here. My guess is the camera mate.

Wow, where do you get that light bubble photo from?

Thanks for the link. I'm very near the blue circle, which means I'm in the pink. You are in the green.

I just need to move a couple of suburbs away for darker skies.:blink:

That is a superb image!!!  Noel Carboni's actions are a superb (and very cheap) way of one-click noise reduction, but you need Photoshop to use them.  There are also specific noise reduction packages that do a great job on astroimages and don't affect the colour.
