M33 (reprocessed)

I've often wondered how my post processing skills have changed over the years, so I decided to find out by extracting some data which I acquired c2.5 years ago and performing a reprocess on M33.  The LRGB image with an Ha blend into the red channel represents just over 15 hours and was taken with my ED80 on my NEQ6. 

The main post processing differences are:

- I corrected for a slight camera tilt via PS, this results in slightly oddly shaped stars towards the edges of the frame. You should be able to see theses defects in the old image if you zoom in.

- PI's Photometric Colour Calibration was used on the new image. 

- PI's HDMRT was used on the Lum to increase the contrast (before I used the PS High Pass Filter)

- PI's Dark Script Enhance was used to enhance the galaxies dust lanes.

So, still a mixture of PS and PI but now with more PI.
