shot 41 Dra and Saturn (Toronto)

Last night's imaging run highlights.

		Um. Didn't see anything at first. Was off target...
		Thar she blows! Wiggly!
		That's better. 41 Draconis (A and B). Headlights in the night. That's SAO 9002 (the C component) off to the right. North is bottom-left; east is bottom-right.
		Focusing with the Bahtinov mask.
		Single star, focused. ζ (zeta) Ursa Minoris, I believe.
		Back to 41 Dra.
		Long exposure to check drift angle.
		Drift angle made parallel to long axis of camera frame.North is down; east is right.
		Imaging run of 41 Dra begins.
		Over 130 images captured. 0.5 or 1.0 second exposures.
		Spotted Saturn through the trees. And moons! Left to right: Titan, Tethys, Saturn, Enceladus, Rhea, Dione. And I think Hyperion! North is up; east is left.
		Saturn, focused, at 1/20th, 1/30th, and 1/60th. Captured about 20 frames.
		Darks, for stacking and noise reduction.
