jjongmans Posted June 9, 2013 Report Share Posted June 9, 2013 The nights are very short this time of year, so I spent five nights gathering data of this nebula to get the brown color. It wasn't easy under a SQM 19.14-19.55 sky. Seeing was between 1.97" and 2.84". More details on my website. Link to comment Share on other sites More sharing options...
GerhardB Posted June 9, 2013 Report Share Posted June 9, 2013 Hi Jeffrey, This is an amazing achivement under this amount of light pollution, the nebula is quite prominent in your image. Post processing is very good, though there is still some noise visible in the full resolution version. Pixinsight offers several noise reduction methods, which - with the right choise of parameter settings - work very well and unobstrusive. Best regards, Gerhard Link to comment Share on other sites More sharing options...
jjongmans Posted June 9, 2013 Author Report Share Posted June 9, 2013 I did some noise reduction in the low SNR dust regions: Link to comment Share on other sites More sharing options...
afesan Posted June 17, 2013 Report Share Posted June 17, 2013 If you´re under polluted skies this is a very meritory image Jeffrey..as the Iris nebula isn´t precisaly an easy target ¡ Overall ,the image is very pleasant to my eyes... Gerhard gave you a good idea using some light noise tools.. Regards, Antonio Link to comment Share on other sites More sharing options...
