Perkil8r Posted July 15, 2013 Share Posted July 15, 2013 Very nice. I prefer the colour in the first but the processing in the second if that makes sense? Certainly a cracking image either way Link to comment Share on other sites More sharing options...

Sheila Posted July 16, 2013 Author Share Posted July 16, 2013 Thankyou all. But i really need some lessons on processing.... i struggle a bit there Link to comment Share on other sites More sharing options...
Guest peter shah Posted July 16, 2013 Share Posted July 16, 2013 I use the standard curve method, it uses curves and levels in Photoshop to pull out the detail... which is similar to DDP process....also with narrow band imaging you cant think of the exposure weights in the same way as RGB, with RGB you are trying to capture a "true colour" image so the exposure value has a ratio that should give a result similar as to how the eye would see it....every object has different amounts of S2, O3 and Ha so the object themselves dictates how much exposure is needed in each filter to give enough signal. Generally there is lots of Ha and significantly less O2 and S2 so more exposure in those frames....hope this helps a little. Link to comment Share on other sites More sharing options...

I will just get as much as i can and go from there. Sheila Link to comment Share on other sites More sharing options...

Guest Kheldar Posted July 16, 2013 Share Posted July 16, 2013 I was asked to have a go at Hubble'ing it ... first ever attempt for me too but I suspect it needs some more blue (Oiii) and LOTS more Sii (Red) to really drop the difference in colours out Link to comment Share on other sites More sharing options...

BAZ Posted July 17, 2013 Share Posted July 17, 2013 That is fantastic, really just a testament to how much time and effort you have put in getting it. I like the first one, it looks more natural, if there is such a thing with all that jiggery pokery. Link to comment Share on other sites More sharing options...
