Camera: Peltier-cooled Canon 350Da (TEC@10C)
Location: Emmen, The Netherlands

High resolution: (1,14 Mb)
DSLR-LLRGB post-processing work flow  according to Scott Rosen's video tutorial:
 
Original 32-bit floating point RGB image in Photoshop CS3:
 
-Convert to 16-bits RGB
 -Color Balance using Levels
 -Star Repair in 2 itterations with layer masks to guid effect
 -GradientXterminator (med/low and fine/med)
 -Adjust Black Point using Levels
 -Digital Development Processing in Nebulosity 2.5
 -Star Repair

Luminance processing:
 -Convert to Grey Scale for Luminosity processing
 -Convert back to RGB [RGB reconvertion is only done for easy of interpretation of PS histgram and tools]
 -Curves, selective on weak Ha clouds in the background and Ha whisps in NGC6992, with anchored background and highlights
 -Carboni's v1.6 Deep Space Noise Reduction [Removes noise from background, not DSO]
 -Curves, selective on weak Ha clouds in the background and Ha whisps in NGC6992, with anchored background and highlights
 -High pass filtering on the details in NGC6992 (40px soft light blending; Don Goldman method)

RGB color processing:
 -Slightly anchored curved to bring up brightness of  RGB image in similar order as Luminance
 -
Carboni's v1.6 Space Noise Reduction
 -Carboni's v1.6 Less Crunchy More Fuzzy
 -Increase saturation using Adam Block method, 3x
 -Selective color, Reds (-100% Cyan), Yellow (-100% Cyan), Blue (+100% Cyan, -100% Yelllow)
 -Insert Luminance at 100% opacity
