Don`t let the plastic design and basic optics put you off. I have tested on my own 10" dobsonian, where I got acceptable 

results through both an eyepiece, and through my SLR body for prime focus observations (t-adapter + t-ring needed)

As always with our products, the results you get will depend on the quality of eyepiece / telescope used, seeing 

conditions and observing techniques
