Would love do some starry night landscapes. Looking around now for a reasonably portable tracking device for several minute star exposures to composite over static landscapes.
The astroTrack TT320
seems to be a very good device, with excellent tracking accuracy and very compact to transport. The price seems reasonable for such a specialized piece of equipment, but perhaps there are also local possibilities to rent such a unit for a limited period of time.
It looks like the fastest way of working is by mountiing it on a geared tripod head, to assist with alignment with the celestial axis of rotation, and use a ball head on top, to position the camera for the best angle of view.
Of course, the landscape features will be blurred, but the long exposures will help to get also faint stars to build up a reasonable exposure level. A composite of the landscape with a relatively short exposure, and the longer tracking exposure could produce some stunning vistas.
