  Orion Wide Field:
Feb 16-17, 2009; Crawford Cemetery, near Oak Ridge, TN


50 mm f1.8 AIS Nikkor at f3.5, Canon-Hutech 400D @ ISO 400, Kenko SkyMemo Tracker mount, unguided.

49 x 1 min subs = 49 minutes, some darks, sky fog subtraction by gaussian blur of image.

This pic illustrates why a cross hatch filter is so desirable for constellation photography.  The bright stars here do not stand out enough.
