No the lens itself is like any lens but it does end in an M48 male threaded end. You attach your T ring and mount it in your camera.
I have bought a tilt/tip adapter for it from Teleskop Services and will be adding it to before the T ring. I think I'll get one of those new copper T Rings William Optics are selling as well for even stronger and more accurate attachment. This type of optic is going to be sensitive to tilt and also its quite long and slightly heavy so that will put pressure on the mount.
On my ML16 I have it fully corrected and supported so round stars to the corners there.

That's interesting to note. I've usually been dealing with 10-15% overlap myself and found that tilt leads to irritating registration errors when merging the panels together. An external tip/tilt adapter will certainly help
The focuser on my Sky Rover has 3 screws on it that allow for the change of focuser collimation. They're fiddling and don't fine tune well out in the field but I've found doing it inside with a 2" Glatter and circular holographic a quick and easy way of getting it bang on at F/5.
