Cannot have been easy doing any form of processing on my shot Kev, down sizing from 150MB down to <200kb has its issues
I think it was the first that was not calibrated, just debayered, registered and then stacked. I calibrate my flats with a bias then stack the calibrated flats. Then calibrate the lights with the master flat and matched darks. Then I debater, register and stack
The main difference between my two shots is that there is a visible dust mote around the centre left
