Scope is well constructed, currently using as a finderscope, objects are much brighter than the default 30mm finderscope that my telescope came with. Note that the scope as straight thru for eyepiece only, I could not get it to focus with a star diagonal. The scope also gives me flexibility to use it as a guidescope in the future. The focusing system is precise but I found the dual focusing to be a bit tedious and focus locks do not work that well, I could still adjust the focus after tightening down the focusing lock screws. In all, a great scope, great value, good versatility.
