M45, the Pleaides
- 8 hours 30 minutes
click image for 50%
51 ten-minute subs. This
image was acquired, calibrated with both hot and warm pixel removal,
demosaiced and stacked using standard deviation in Nebulosity.
Post processing for color in Nebulosity with final amp glow removed
using layer masking, a series of curve applications, slight saturation
adjustment, and jpeg in PSCS3. I am pleased that the tiny
galaxy PGC 13696, mag 17.3, is visible about 1/4 degree west of
17 tau (Electra, the lower right star of the bowl).
There is also a bright astroid, (264) Libussa, that the standard
deviation stack didn't quite remove..
