Customer reviews

Touchy performance, not a hassle-free mount

Review by mxpwr on 30.04.2023 19:33:58

( 3 / 5 )

The mount has mostly a good build quality, with some exceptions (such as a somewhat lose USB jack). The design is pretty well thought through, though the tripod mounting screws are really fiddly.
The USB connection is really touchy, only works stable with certain cables and PCs; be prepared to test around a bit.
Telescope alignment is a breez, very easy to setup.
The main issue of the mount is with the tracking/guiding which is a big hit and miss. Not what i expect from a mount on this price class. Some intrinsic backlash (probably in the meshing) causes lots of issues with the slightest misalignment, sich as increased Ra jitters and oscillations, which need to be dealt with carefully. On a good day rms of 0.5" can be reached.
(The Astroshop customer service was kind enough to check for mechanical errors, but none could be found.)
