Flame & Horsehead Nebula (Orion)

(fritz kleinhans)


Flame and Horsehead Nebula:
March 6, 2010, from Prairie Grass Observatory, IN

500 mm f4 AIS Nikkor at f4.8, Canon-Hutech 400D @ ISO 400  (800 now prefered)
Probably on GM-8 mount.  Good sky for PGO, high transparency.
Some cropping; full scale image.  2.4 arcsec/pixel.

15 x 6 min subs = 90 minutes, 3 darks, temp in 20's F; camera very happy.


(Note the previously undiscovered blue nebula at bottom center.  It is probably an internal lens reflection of zeta Orionis.)
