Tested these data with the three important processing aides.
The "Original" version used the Narrowband Assistant PI script from
@Alex Woronow .
The B version enhanced detail and color saturation in Photoshop and Topaz also with 3D LUT.
The E version is the same original image processed with the new Beta version of General Hyperbolic Stretch (GHS 2.2.2) . This allow separate manipulation of each RGB channel as well a L and Saturation. You can balance the histograms of each channel.
The F version did some Topaz Denoising and sharpening and a high-pass filter was also added to further sharpen the results from GHS.
GHS Forum DiscussionFrom GalaxyMap:Avedisova places this nebula in star formation region
SFR 133.69+0.99 with 86 components including 11 masers. IC 1805 contains at least 10 O-class stars including 3 extremely rare ultra-hot O4 and O5 class stars.
The correct distance to the
W3 (OH) star formation region within Sh 2-190 has been measured with incredible accuracy using radio parallax as 2070 +10 / -20 pc.
In the lower left corner is IC1795, which encouraged me to take this shot. It was processed recently using GHS.
