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
The Heart Nebula in Perseus is an interesting region of red hydrogen clouds mixed with dark nebulosity and bright star clusters. This was a test-run: first light with the Sequence generator Pro combined with the Nikon D750 (with autofocus by PegasusAstro, worked wonderfull). Second test (living dangerously!): first attempt to mosaic automatically with SGP.
The D750 would crash SGP when hitting the “link” button: as soon as I touched that button, SGP would collapse and simply vanish in thin air. Solution: install the 2013 C++ redistributables.
The Optolong Pro filter OR the reducer/flattener (or the combination) imho added a lot of vignetting and uneven illumination to the image, which I had a hard time eliminating. So next test would be with a regular Nikon T-ring. If that does not solve the issue then it must be the F5 reducer. I noticed earlier already that images at F7 with the Nikon were a lot cleaner.
