I think I prefer the unprocessed version

Subject: [TAC] Thor's Helmet in Halpha from Feb 3

I took this image in early February but was only able to take Halpha data. Maybe I will get a chance to finish the emission line data before the object goes out of season. The weather has been terrible this year so far, so I don't know :-)
 
This is 5 exposures of 45 minutes taken with an AP180EDT using an AP 0.75x telecompressor, a Finger Lakes IMG6303E camera operating at -40C with no water cooling and a 6nm Astrodon Halpha filter.

Guiding was done with a piggybacked AP80/900 mm guidescope and ST7E camera
 
seeing was a bit soft that night so I did a bit of deconvolution when processing the image. Maybe I should work on it a bit more: what do you guys think?
