LBN 182 in Cygnus - RGB enhanced with Ha and OIII

Here's a more traditional blending of the Ha into the Red @ 100% and Blue @ 20% plus the OIII into the Green and Blue at 50% using Lighten in PS::



Here's just the HOO via Foraxx using PixInsight:



And finally, here's the pure RGB image:



LBN 182
------------------------------
Not a lot of info about this field of view. The bright blue arc seen better in the narrowband renderings is WR134. The surrounding gas clouds are LBN 182. The Open Cluster ngc6883 is just centre near the top.

Predictably, I shot this recently, focused on WR132, so the framing is slightly different. Here's that version from one year ago:

Session orchestrated by CCD-Commander
Calibration and processing of the RGB and Ha and OIII in PixInsight as follows:
RGB: SPCC, BlurX, NoiseX, Gradient, Curves, HistogramTransform
Ha and OIII: BlurX, NoiseX, StarX, Curves and HT and LHE
Ha / OIII combine with their respective stars done via the Foraxx script in PI

Photoshop processing:
Split channels: Added the Starless Ha to Red at 100% and Blue at 20% using Lighten Blend mode. Added the starless OIII to Green and Blue using Lighten at 50% then Selective Colour and Curves adjustments.
The HOO image from PI was also used. I layered the RGB over that using Lighten and some subsequent adjustment layers.
Small tweaks and small noise reduction then Save-for-Web
