Magnitude: 10.0 Size: 20.0'x10.0'
Right ascension: 20h 12m 17s Declination: +38° 22' 13"
200mm F5 newtonian @ F3.3, SC1.5 toucam
80mm F5 refractor @ F10 guidescope with SC1 toucam and GuideDog
100x35s for the top half and 50x40s for the bottom half.
Captured in k3, debayered in aviraw, stacking in k3 with flat, curves and layered in Photoshop, slight tweaking in neatimage and downsized to 600 wide.
Alas, the image turned out poorly with respect to star shapes. Something must have "slipped" in the optical train, and I am back to wonky star shapes. :-( This is a problem that plagues us mad nutters trying to get F5 newtonians to operate at F3.3. However, I was pleased to get the nebula, and also happy to be able to see it on the laptop screen whilst imaging to top half. I was not expecting that! I could see nothing on the screen whilst imaging the bottom half, but I decided to try anyway. I'm afraid the full depth of this nebula is beyond either my abilities or equipment.
Location: Curdridge, Southampton, UK. 51N 15W.
