Review Summary

Rated 2 out of 5

Scope great - manufacturing horrible.

The scope itself works great... Once you get it aligned properly and fix the manufacturing issues. Mine arrived with a loose secondary mirror, as well as none of the screws for the truss being uniformly installed or tight.. one set of them was about 5 mm above flush, one set was flush, and one was counter sunk 3 or 4 mm. Additionally, the collimation was such that only 1/3 of the primary mirror was visible, the rest of it was telescope wall. After buying a collimation eyesight and tightening the loose bolts, it works great for planetary astrophotography.

A telescope worth owning.

The optics are great, the mount is solid, and it tracks well. My only significant complaint is the lack of adjustable feet to level the scope on uneven ground. Minor gripes are the eyepiece holder is too shallow to hold the large eyepieces I use (Baader and Celestron), and the secondary adjustment screws are hard to see in the dark. Overall I'm pleased with the telescope, but 5 stars are not warranted.
