OK, well that particular function of star-mate would work a treat, but I think you would baulk at the price
Are you coming out to Astrofest? If so you could borrow one of mine and see if you can work with it. Unfortunately you would have to keep the camera and control box together some how, attach it to the mount possibly.
Have a think about it and if you aren't coming to the astrofest we might be able to work out some sort of get together and look at the feasibility of using it.
I'm coming down to the Bot Gardens for work but I don't think it is until mid August though.
