This is my November (Fall) 2012 Davis Mountains astronomy pictures page. This was a fairly cloudy trip so it's heavy on moon, daylight, and time lapse stuff. In fact this trip saw my first efforts creating some time-lapse videos with my DLSR cameras. Be sure to watch the HD versions, full screen, to see all the detail. Shooting details are on the YouTube pages.

See details on my PacMan Nebula page here. Ha = Red, O3 = Green & Blue, Red blended into the luminance. 28*5 minutes Ha plus 28*5 minutes O3 = 4.7 hours total exposure
Check my Flaming Star Nebula picture page for details, and the monochrome H-alpha component of this image.
You can make out a bit of earthshine as it sinks into yonder ridge ;-) Astronomer info: Shot at 6:41 p.m. central time 11/14/12; 1.88% illuminated and about 26 hrs 40 minutes old. Skies were favorable for catching it way before it set. Nikon D7000, Nikon 300mm f4 lens at f4, 1/8s, ISO 1600.
This yellow moon was around 50 hours old and 7% illuminated on 11/15/12.
