I don't get the chance to use my SkyTracker enough, I've only used it 3 times, so I'm selling it. Included is the iOptron ball head.
It works really well for widefield DSLR shots plus it's pretty good as a quick grab and go mount for the PST.
It's this model:

New price would be $568, I'm after $420 plus postage.
I've also attached a shot I took with it at IISAC.
