Recently recaptured Omega again this time I went for shorter subs 20second only.

This is about 6 minutes worth of data equal number of darks and flats.

Unguided but tracked

Hopefully all the technical issues are sorted out, so we can move on to discuss the image!

To me it has a nice 3D look to it, the bright stars in the centre seem to be in front of the rest of the stars.

Looks very nice Trevor. The colours are nice and like James has said. It has a real 3D look.

Nice work.

Nice image Trevor but it looks like you may have clipped the black point a little on this one. The background is super black and you may well have lost some of the dimmer detail. Keep an eye on the histogram and keep the left edge in the clear. You also have a bit of a blue cast to the background around the bright core and the outer part of this glob.

Nice attemp but watch the histogram.

Use of shadows and highlights in PS will prevent clipping. I saw clipping too in the image, as well as a large ring of brighter sky and then the rest very dark. The core stars are a little pink and the outer core is a little too blue. Some colour adjusting and this will look a lot better. Nice round stars though and the tracking looks good. If you guided with this image your data would be better and you would not have to stretch it as much to get the same level of detail showing.

Thanks Paul will avoid using LP removal process which seems to cause some issues

I did this to the TIFF file this time around the File first had histogram, curves, noise levels and dynamic background extraction applied in PixInsight LE

as per first image these adjustments in CS3 plus a smart sharpen and adjusted selective colour black

This one looks better for sure. Maybe just a little too blue in the sky and the stars just a tad pink. A much better presentation all the same.
