Sadr Region - Reprocessed in HOO

[mightymonoped]

Thought I'd have a go at reprocessing this capture from June in  HOO using some new techniques.

Extracted a Star Layer using Starry and Starless versions of the stretched and initially processed capture.

Extracted Starless Red (Ha) and Green (OIII) channels. 

Recombined in new image using HSL colourise (Orange/Red to Ha and Green to OIII), then used Layer Mask for Ha layer to reveal the OIII layer beneath, Levels and curves to finish.

Camera Raw Filter to address Contrast, Texture, Noise, Colour, Clarity and Detail.

Final finishing off with High-Pass filter before remerging with reduced Star Layer.

Weak HLVG filter then finish off with AstroFlat Pro for final touches.

 

WO Redcat 51
ASI294mc pro -10C unity gain
Optolong l-eNhance filter
Star Adventurer tracker

 

Clear skies all,

Tony

That’s a great re-process, techniques to extract the most from dual band filters on OSC cameras are evolving and  your image shows so much detail in this region , you’ve really got good star shape and colour in this process flow and I do like the burnt orange hues you’ve selected - a favourite of mine. 
Great work 

Bryan

 

edit to add I’m still so impressed you get such amazing images from a star adventurer mount - just adds to  context of this image.

Cheers Bryan, I’m really enjoying some of the great techniques that are being shared out there. It’s great that prior captures can effectively be rediscovered. 
 

re: the Star Adventurer, in some ways it promotes concentration on the basic issues, balance, alignment and setup rather than worrying about the finer point, like what degree of guiding error is occuring. It’s all about context, I suppose. If I’m using quality glass like the Redcat, and getting good results on the ASIair screen, that’s all I’m worried about. The CMOS camera I am using gives great results at 120s and 180s. I believe there’s nothing to be gained from longer exposures due to the conditions I am capturing in most of the time. This all plays into the Star Adventurer’s  court. When I move up yo using my ED80 again, I’ll be looking at a more robust mount but until then the SA does sterling work as long as it’s balanced in both axes.
