Or actually maybe more still a foetus, as the Soul nebula is often seen as a foetus or a little bear. Imagination! I’ve never seen a Soul in it: how does a soul look like anyhow?
The frames were taken last week Tuesday, in horrible conditions: high clouds, fog, and tons of moisture. Frames were whitened out by the fog, and all street lighting reflecting on the fog.
The image is a mosaic, about 6000×7400 pixels. More then 7 panels were composed with APP to create it. However, due to the fog, soo many gradients were present, I really had to get all tricks out of my sleeves to get a decent picture. It was processed with all parameters in APP at max (Normalisation, blending) and also cropped the outer edges which could not be salvaged. Material used was: Nikon D750, no filters, EQ8; Esprit120, 400mm guidelens with an ASI290MM
I had finally a break in the clouds, no moon, to capture some color for my NGC3628. This color was already long waited for ( I started the first luminance February 24th). So I added 7x300s Blue, Red and Green. I combined those in Photoshop with the previous Luminance. See all details on Astrobin
I’m not utterly thrilled by this result it can certainly better, I need to add additional Luminance data to reduce the noise and increase detail. This was actually more an exercise in combining NEF Nikon D750 color data taken by the C11 with Starizona reducer with monochrome ASI183MM data taken with the Esprit 120. This was done with AstroPixelProcessor 1.071. As you can see it worked wonderful.
The NEF color frames were split along the RGB color channels and combined with the Luminance result using the RGB Combine tool. The luminance noise was still very present as the Gain settings (230) were too high during the ASI183 capture.
There are some artefacts like the obvious magenta colors top left, and the top right cut-off angle: I need to look into these.
