Here's my take on NGC 253 Sculptor Galaxy (aka Silver Dollar Galaxy). I've probably gone overboard with the saturation but that's OK because our dollars aren't silver anyway!

This was a relatively brief run of

26x 120s Lum
12x 120s R
12x 120s G
12x 120s B

Nice shot Kevin.

I've had to have early nights but I really want this one with my latest scope.

A very fine result Kevin.

A close examination of the histogram shows that you can safely make the background much darker without any information loss.

Thanks Jacob.





Thanks Kevin. Which scope is that? I would have liked a little more focal length than the 550mm of my Esprit.





Thanks Mike and Trish. I collected this data at the end of a run of another target and stopped at 3am not expecting I had enough. I did a quick process this morning to see what I had and was pleasantly surprised (which is why I posted it). I still plan to get more data and will do a more thorough process then.


Cheers, Kevin

I have a loan of a deforked Meade LX90 ACF 8" F10 SCT. 2000mm FL. Should fit it in nicely.

Yep that should do it well. I've bought time on a Planewave CDK 431 mm (2912mm focal length) at iTelescope. I'll use my Esprit data with that and see what happens. I've combined lum data so far and it's looking good!
