June 22, 2020: NGC 7000 and first light of new imaging set

[michael.h.f.wilkinson]

Just finished stacking 27 5 min subs of NGC 7000, taken with the ASI183MC with my new Optolong L-eNhance filter and Carl Zeiss Planar 85mm F/1.4 on the EQ3-2 mount. Stacked and processed entirely in Astro Pixel Processor, with darks, flats and bias frames.

I stopped the lens down to F/2.8 for better star shapes in one of the corners, suggesting the lens might not be entirely square on the chip, probably due to the Contax/Yashica - Canon EOS adapter having a little play.

I could easily get 5 minute subs without guiding at this short focal length. Star colours are bit weird, due probably due to the dual-band filter in use, and some red bloat is showing around stars. Still pretty chuffed at the new set-up. I might have a go at the Veil tonight.

I think it came out very nice, it would be nice to have a clear sky, 6 weeks, terrible here.
