Colimation is difficut
If this telescope leans a body tube, Optical Align will shift greatly. A wonderful image is shown if collimation is perfect.
It has Polar scope well. However, tips go into exact Polar Alignment.
Tracking is Good. RA is liable to delay a little. A check and adjustment are sometimes required for the Dec direction.
Mastery of knowing the bundle condition of various screws is a required telescope.
Movement was not difficult for me.

Optics excellent, mechanics a work in progress
The NOVA optics are quite good, but cannot see their best use in this instrument. Collimation is an order of magnitude more difficult than with a non-rotating nose Newtonian, and cannot be made exact for more than a single point of rotation. Support from JMI is poor to non-existent (they are defensive at best), and accounts for some of the poor rating. RA tracking is smooth and accurate, DEC slow motion is erratic. Setting circles work quite well. Weight is almost unmanageable for one person.
