Excellent widefield of this one. Your guiding/tracking is great.

The APOD image is amazing, I like the faint galaxy(IC 1296) that appears at the 2 o'clock position. Interesting what adding H-alpha filtration exposures and shooting it with two separate, very nice scopes and plenty of aperture can do with these faint gems. The guy or guys that shot this have an awesome gallery, worth a look.
