Thor's helmet OIIIRGB, yeah another one
Here's my version of this elusive target. Captured with the WO FLT132 with Flat68, EQ6, and unmodded 400D. I took this over 7 nights from 30 Dec to 11 Jan, but only got to process it now.
8hr 40min of OIII at ISO800, 10min subs
8hr 30min of RGB at ISO400, 10min subs
I couldn't get any of the Ha extensions, they were just too faint for an unmodded dslr, perhaps I'll visit this again later when the equipment changes.
The heat did no good to the DSLR, I did take darks at approximately the same ambient temperature (+-3degC), but obviously have no idea what temperature the camera is actually at. Flats were taken at the end of each session with a lightbox.
Thanks for looking
George
