NGC7635 bubble nebula in H-alpha from urban skies
« on: 2014 August 12 02:10:35 »
Hi folks,

taking advantage of the summer break I have decided to take my chances again with PI, which I do not master *at all*. Still this is good time for learning so I've decided to grab some old date from my computer and process it with PI. This is the bubble nebula taken with a TEC140 riding on a Paramount MX and with a Starlight Xpress SX-H9 camera, 130min in 13x600 guided subs. (Oviously) I've used PI to pre-process, stacking, DBE and ACDNR to remove noise. BTW I've been greatly impressed by the ACDNR routine, though I want to try noise removal with wavelets so that I can try to sharpen fine details while removing the noise. In any case this is my second attempt at using PI, so please bear with me, I'm trying to learn :)
The final result is

Comments and suggestions are more than welcomed :)

Best regards and thanks,
