It way back Wednesday and I did this back in 2016 and have had another go at it.

6 x 300sec @ ISO800 with calibration frames

Processed in Startools finished in CS6 and final noise reduction with DXO Optical pro 11

This looks like you have some great data but the black point is very clipped.  I wonder if this was to reduce burning out the core.  How are you stretching the image?

Yep I know there is only 30 mins data and it's quite noisy so I was trying to reduce the noise. My processing is in Startools that is where the main global stretch takes place. I will revisit this so watch this space.

Martin here is a reworked one.
