+Graham Posted January 6, 2013 Share Posted January 6, 2013 Last night I decided to put the cloud cover to some use so I spent over an hour collimating my Newt to get it spot on. Tonight I decided to take full advantage of the clear skies to get this last chance image of M 42 before it disappears below my horizon. Because of its low position in the sky directly above Ipswich docks I was limited to 30 second subs because of light pollution. I managed to collect 101 subs and after sorting out the bad ones, the ones with planes flying through and a couple of the Police helicopter sauntering past I ended up with 85 usable subs. The best 95% of these were stacked. Helios 200 Newt. Cannon 350 D unmodded 78 - 30 second subs at ISO 800. 21 Darks 21Flats Stacked in DSS Very very light processing in PS 6.

Antares_Paul Posted January 7, 2013 Share Posted January 7, 2013 I won't post the processed image Graham but there is a lot of detail available. A lot going on behind the image too The DBE process in PixInsight extracted this from your image. Regards. Link to comment Share on other sites More sharing options...

+Graham Posted January 7, 2013 Author Share Posted January 7, 2013 Hi Paul. Ok I give up what is it ??? Can you please explain. Thanks Link to comment Share on other sites More sharing options...
Perkil8r Posted January 7, 2013 Share Posted January 7, 2013 I think it refers to a gradient Graham. Link to comment Share on other sites More sharing options...
Antares_Paul Posted January 7, 2013 Share Posted January 7, 2013 ^^ Exactly that. Uneven illumination and colour caused by light-pollution gradients. I certainly suffer from it here. GradientXterminator plug in for Photoshop does the same job. Regards. Link to comment Share on other sites More sharing options...
+Graham Posted January 7, 2013 Author Share Posted January 7, 2013 Cheers for that Paul. I am not surprised the docks are lit up like the proverbial Christmas tree and 42 was about 40 degrees above it all. Link to comment Share on other sites More sharing options...
