Pacman now with more nebulosity

While I am waiting for enough astrodark to make it worth while up here, I have revisited my Pacman nebula data from November last year, since I had the feeling that there were more nebulosity there to bring out. Most Pacmans I have seen posted on the web are processed quite hard and only bring out the central parts - maybe to emphasize the Pacman figure. However, I just saw a Ha image of Pacman at Astrobin that reveals a lot of surrounding Ha-nebulosity, particularly to the right of the nebula (http://www.astrobin.com/full/144610/0/).

So here is my revised version showing more of that surrounding nebulosity. Below it I post my old version for comparison.

Processed in PS CS5 now also using the APF-R technique (http://www.cedic.at/apfr/) to bring out more faint stuff and a round of Hi-pass filtering to bring out more structure in the nebulosity.

Equipment: ES 127EDapo with a Canon 60Da on an EQ8

29 x 360 sec, so totally about 3 hours.

Any comments and suggestions most welcome - I am sure it can be improved
