My first attempt at NGC281 was with my ED 80 and taken with my colour camera - and I definitely thought the result looked liked the Pacman.

So, whilst attempting to image this object with my Esprit 150, I thought I'd end up with another Pacman, albeit somewhat more detailed. However, the more I looked at my narrowband result, the less I decided it looked like the video game character. I think this is because my eye was drawn to the various nebula details, which tend to be absent in a broadband approach but reveal themselves with a narrow-band technique. So, for this bi-colour image, I decided to try to enhance the details by experimenting with colour contrast curves and the Pixinsight script DarkStructureEnhance.  The image represents 9 hours total integration time. 

(If you are still interested in seeing the Pacman, then you need to rotate the image by 180 degrees).

Nice, I like the faint nebulosity around the edge of the nebula proper. There's a nice 35 effect in the centre as well.

Cheers, Ian

Thanks for the comment Ian.

Ideally, I'd like to have captured a little more faint nebulosity but this target has now disappeared below my local horizon, I guess that is a downside of attempting to image 7 targets simultaneously.

I see what you mean about the 3D effect, I hadn't noticed it until now.

That’s spectacular. I love the colour graduation and how it emphasises the fainter detail within the centre.

Thanks Ken - yes, I was using contrast curves in the central region separately for the RGB channels in order to maximize the details and also (hopefully) end up with a colour that I liked.

      NGC281 - The Pac-Man by Chris Kennedy, on Flickr
      35kph gusts of wind, and REALLY bad guiding due to a lack of drift align and the star being "blown away", but managed to get a little something out of 30x360s light frames, also a new target for me, one I want to come back to under better conditions and with other wavelengths of light to make a full colour image.

      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

      No clear nights in sight to keep me awake so great re-processing weather over here in Sweden! This is data from end of November. About 3 h (29 x 6 min) of the Pacman taken with my 5" ES apo and Canon 60Da at ISO 1600, so pure RGB.
      Comments and critique most welcome of course
      Cheers

      The Pacman Nebula in Cassiopeia (NGC 281). Captured with APT, Canon DSLR, Baader coma corrector, Hα filter, .25m f/4 reflector, at ISO800, 19x600sec exposures. Guided with PHD2, finderscope, Atik16ic. Registered and stacked in Iris, processed in PixInsight, no calibration frames. The last 5 exposures were taken in a sky with no naked-eye stars visible (due to thickening high cloud) and the first 6 were badly focused! So definitely a session to learn from...

      Well its been a long time coming but I have managed to get back into the obsy and start imaging again. :-) 
      I was very rusty setting up and my tracking started off good and then started to fail as the target was straight overhead.
      Anyway without much ado - Here is the result - Just 3 x 10 min subs (The rest got scrapped to the poor tracking) with a bit of pixel bodging in PI
