Why I am doing this?
First of all, by selling my TG-SP II, I got back some cash together with this Mark-X, but even if I inject 1/3 of the original cost of my TG-SP II, I would be able to get back a fully operable mount, so it's a real bargain, indeed.
I've a plan to remove the slow motion control of this altazimuth mount and re-fit it to the Mark-X as the DEC axis. This will facilitate high power imaging. In addition to that, from what I've seen, this part should be motorized rather easily, so I will have a dual axis mount for higher power imaging.
For the other axis, maybe it could be used to aid polar alignment? I don't know...
That's the first time I bought stuff from www.taobao.com, see how it works out. The pricing is definitely attractive.
