Very good value
Pros: Cons: Comments:I use this eyepiece in a 102mm f/9.8 refractor to give wide field views of M42, M45, Double Cluster and similar targets. Actual measured TFOV is 1.76 degree in this telescope. Views are sharp over 90% of the field with just a little softness near the field stop. Size and weight do not overpower the scope on an equatorial mount. Build quality is very good. I am quite pleased with this eyepiece and would recommend it for f/10 scopes. The only shortcoming was that it did not come with end caps, just a "bolt" enclosure.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com
