Eastern Veil - NGC6992/5 Mosaic

[RichieJarvis]

Hi All,

I've been working on this the last few clear nights - my goal was to capture 2 hours for each pane of Ha and OIII data, which I am pleased to have achieved Just spent the last hour processing and matching it all up. Method was to DDP the stacked Ha and OIII frames (x4), pull into photoshop, and merge them with a 10 pixel feather. I then saved both the mosaic'd Ha and OIII data off, realigned in MaximDL, and saved. I then ran both aligned mosaics through CCDSharp for 8 iterates of Deconvolution.

Whilst that was running, I pulled the aligned Ha and OIII data back into Photoshop, and combined them to form a colour layer. Ha was set to Red, OIII to Blue, and a blend of the 2 for Green. I then made a 'base' lumiance layer from the colour data by desaturating it.

Once the deconvolves were finished, I pulled these into Photoshop and blended with the base luminance layer using a Hide Layer mask. I then ran a High-Pass sharpen and blend, followed by a Smart Sharpen and blend.

I was left with a Colour layer and Luminance layer, which I adjusted using Curves to taste.

Pretty pleased with the result

Great result Richie, I wouldn't even attempt a mosaic in our limited observing sessions.
