I do have to second about what Roland says about the basic accuracy of the 1200.
I've a 1200 in a dome supporting an 8.75" F12 achromat with some nice Parallax rings. When first installed, I did two daytime alignments with the sun. I followed that up in the evening with a few SkyX/T-point models to get my polar alignment miss (very carefully the old fashioned way with a 20mm X hair eyepiece, 10 stars on each side). After the third model, my altitude adjustment was called "excellent" and my azimuth adjustment "good enough". But I'm a firm practitioner of going against the principle of "the bitter enemy of good is better" so I disconnected the SkyX and did a drift on a star low in the east. After about 40 minutes, I had it down to where the star stayed put on the x-hairs at ~135X, for a good 10+ minutes (I slightly defocus the star).
I then used the hand paddle to slew to and sync on a star close to the equator and meridian. Now slews typically put the object within 3 or 4 arc minutes of center at the worst and typically nails the planets.
That's pretty good in my book, especially with no model!
BTW, what are the symptoms of a dead hand paddle battery?
