Double cluster between Cassiopeia and Perseus

When I was planning out my photo of Comet PanSTARRS within 2° of the Andromeda Galaxy I found this great double cluster between Cassiopeia and Perseus. The top left cluster is NGC 884 and the bottom right is NGC 869 (they are both toward the center of the image). According to Stellarium, they are both magnitude 4.0 and about 0ยบ30'00" in size.

68 subs, 10 dark, 10 bias; subs at ISO 1600, f/5.6, 300mm, 1.3 sec
About half of my images came out blurry or with a little trail, so I should probably run this through DSS again and omit a higher percentage of the bad frames. The brightest 'star' in the center is supposed to be two individual stars and not a horizontal smear.

In any case! The stack does deliver a bounty of stars in two distinct clusters, which makes this a very cool target.
