My latest target is NGC 253 - again. I think I have imaged this every year for the last 3 years. There have been improvements in image quality and my processing skills each time but...I am never really happy with the result.
This year's effort is attached. It only contains 4 hours of Lum and 4 each of R, G and B. All 5 minute shots unbinned. Taken with PW CDK 12.5 and FLI PL16803.
Also attached is a version with Ha added. I am sure it is too scarlet for some (many!) - what pleases me about this is that in trying to keep the red under control, the image is less saturated and stretched less.
Here are links to larger resolution images:

Both can do with another 3 or 4 more hours of Lum - hopefully this week will remain at Coona so I can collect this.
I am sure these would look better with more data and so I should combine work over the last few years. Its worth giving this a go I reckon.
As always comments and criticisms are welcome - all processed in PI so if you have thoughts on how to refine the images with PI, definitely give me your views.
