Hi all
Though Ive already got NGC 2032 I re-imaged it thismorning, this time re framed to fit in NGC 2014 and the strange ringlike NGC 2020.
6x15 minutes, ISO 400, Idas UV/IR and Baader UHC-S filters, MPCC , Modded 350D. 10 inch f5.6 newtonian, off axis hand guided.
Flats, darks, offset processed in Iris, then Photoshop. Resized in PSP4 (seems to give less compression artifacts then Photoshop.
Star Atlas Pro used to locate and correctly frame the objects
Sadly, upon locating a guidestar, it was a shapeles blob, the seeing was awful. Sky was reasonably dark for Newcastle, but very bad seeing. I knew no matter how careful the focus stars would never be pin sharp. The scope had been left out all night too, so scope would be temperature equalized. Also, the wirerd weather, it seemd to be getting WARMER, not colder as time passed and astronomical twilight approached. Also,warm dry wind gusts from the east were coming through, now that was odd as easterlies are always cooler and moise as the ocean is less then 10 ks away, but this felt warm and dry. Most odd indeed.
