Comments about Pro Optic Pro Optic 2", 90° Mirror Diagonal with Dielectic Coatings:
Great unit that is well made. Excellent price compared to others out there on the market.
I like the fact that the barrel tapers towards the mirror housing as this further inhibits the unit from potentially falling out of the drawtube when the temperature drops.

This 2inch dielectric coated star diagonal can not be beat for the price. The fit and finish is great and optically provides exceptional views.

Comments about Pro Optic Pro Optic 2", 90° Mirror Diagonal with Dielectic Coatings:
I purchased this unit to replace the stock 1.25" diagonal that came with my Orion 100mm f/6 refractor. I spent a few weeks researching all 2" dielectric diagonals that are out there and this one totally fit the bill in both form and function and price as well. This diagonal rivals others that are as much as twice the price. I was able to use it immediately and the increase in image brightness and resolution was very obvious. I do exclusively DSO viewing and with this diagonal it really helps squeeze out the finer details in especially dim objects. It came very well packed and the 1.25" adapter that came with it is also very nice. Again for the price, this is truly a deal to be had and will certainly increase the performance of any scope for which it was designed.
