peter shah Posted February 5, 2019 Share Posted February 5, 2019 Imaged with my AG12 and H35. A massive task to tame Alnitak, it took over 12hours to process this one. Exposure times were 4x900s in H-alpha, 4x900s in Red, 4x820s in Blue and 4x640s in Green. Processed in Photoshop and Lightroom.

tooth_dr Posted February 5, 2019 Share Posted February 5, 2019 That’s incredible, what you achieve in the time you do is something else. Link to comment Share on other sites More sharing options...
ollypenrice Posted February 5, 2019 Share Posted February 5, 2019 A classic composition and this is one of the best renditions ever. Alnitak remains bright (dammit, it is bright!) but the hours of processing are totally invisible and that's what counts... Olly Link to comment Share on other sites More sharing options...

PhotoGav Posted February 5, 2019 Share Posted February 5, 2019 Great work Peter, well done! I’m interested to know why and how you arrived at the different exposure times for the R, G & B filters? Link to comment Share on other sites More sharing options...
Tim Posted February 6, 2019 Share Posted February 6, 2019 Stunning Peter, absolutely stunning. Not easy to get that amount of definition and distinction in the area immediately left and underneath the horsehead itself, the true context of it is seen much more easily this way. This is not a criticism, just a query, with such obvious care taken over the processing, you opted to leave the satellite trails, and I just wondered why?

This is the best example of a great image with almost no data (Olly, this is the image to which I referred even though I had not seen it yet). Not only is this a great image with a grand total of 16 subs , it’s the BEST example of this target IMO Rodd Link to comment Share on other sites More sharing options...

The whole area is plagued with aircraft and satellites. if you look around this rough stack you will see how many I had to remove...Still got a couple to do. You can even see where the navigation lights of and aircraft has flashed and shown its engine housing as its flown across the FOV....and there is a nasty reflection from Alnitak which although I did a repair was mostly cropped out. If I had have don more subs I could of easily removed them with an SDmask or sigma clip stack. Link to comment Share on other sites More sharing options...

I’m interested to know why and how you arrived at the different exposure times for the R, G & B filters? I have weighted my exposure to give a more or less correct colour balance. This saves on wasted exposure times where you would only process the heaviest signal only part way to get the correct colour. This method I can give equal curve stretches to each frame. It also makes colour balancing easier. 4 hours ago, Rodd said: Wow. You certainly tamed it.
