66SD + Modded D60 + Byers Cam-Trak = good idea?

- Modded Canon D60
- WO Zenithstar 66SD
- Byers Cam-Trak mount
For those unfamiliar with the Cam-Trak, it's a very accurate, tiny GEM for camera tracking and can carry a 10 lb load. It is rumored to have < 10 arc-seconds of PE. More here:
Because the 66SD is so light, the Cam-Trak will be able to carry it with the D60 camera attached. I realize that my exposure times will be limited at 388mm focal length, but it was the cheapest route ($250 for the 66SD vs. $1000 for a nice Canon lens).
Does this make sense? Is 388mm too long a focal length for unguided imaging?

3 free things I can suggest to help if your not already doing them is , Polar alignment(drift if you can) , Bahtinov mask (if you cut your own) , Deep Sky Stacker.
Hope to see some shots from you soon.

He found that it was important to get a good weight balance using the heavier lens (the 500mm is some 5 lbs and the 250mm are about 1.25 lbs)

Nice mount! Where can you buy this?
An ad in the wanted classifieds on CN and AM could bring some lightly-used Byers Cams out of the closet. They're top-notch mechanical quality Ed Byers is known for.
