Reviewer: Joseph Guzman
I own the complete set, for their cost, they deliver great and crisp clear views. Their good construction will make them last a long time. It was a good investment.

I recently used the 9mm #8921 EXPANSE wide field eyepiece with my f5 8" reflector and the performance was outstanding. Views of the moon and Jupiter were breathtaking and the clearest I have ever had. The eye relief, wide field and large lenses work great for some like me who must use glasses. It sure beats looking thru those pinhole lenses on other manufactures 9mm eyepieces

I have the 15mmExpanse, and absolutely love it! The views are sharp as a tack and crystal clear. The AFOV is excellent, and this EP also barlows quite nicely with no loss of detail or contrast. The 15mmExpanse has become my favorite EP so far, and is the EP that gets the most use, for everything from casual observing to sketching.

For the price these get 5 stars. I bought (2) 6mm and (2) 9mm for use in my bino viewer. They work great. I have more expensive eye pieces and these might not be in the same league, but they are close for a fraction of the cost. Field of views are nice and wide.

Wonderful coatings makes this ocular a fast coming favorite. Bought to use on a Stellarvue SV 50mm scope and works well with it. Also allows 43x and 86x on my W.O. apo for a well rounded magnifications with my other eyepieces. Troy
