...featuring... Err... Starring M45 Pleiades open star cluster and some of its ghostly nebulosity.
Sad note: my camera got plagued by a good lot of red hot pixels. They are nasty.
Good note: Astronomik CLS-CCD clip-in filter for Canon EOS APS-C cameras is a light pollution killer :]
Acquisition time: JD2456984.32694 (22.11.2014 23:50:47 MSK).
Image orientation: something like straight.
Equipment:
Canon EF 70-200 f/4L USM backed by Astronomik CLS-CCD clip-in filter on Canon 60D (unmodded) riding #Polarie.
Aperture (effective) 40 mm
Focal length 200 mm
Tv = 120 seconds (risky business, trailing is apparent)
Av = f/5
ISO 3200 (overdone, perhaps)
Exposures: 40 (plus 22 dark frames, plus master bias from the library plus 100 flat-field images)
Processing:
