Provides nice views with my PSTPros: Cons: Comments:
I purchased this to provide a higher power image with my Coronado PST than the stock 18mm Plossl supplied. While I have not compared the 12mm CEMAX to a comparable focal length eyepiece, I'm happy with the views this eyepiece delivers.Bottom Line: Would you recommend this item? Yes

Lightweight,Strong Construction,Compact,Quality Lenses,Easy to UseCons: Comments:
I don't really see a huge difference in useing this in my PST over a good general purpose plossl, say a TeleVue. However it performs well within the limits of the PST's limited 40mm aperture. Maybe in a larger solar scope the difference would be more noticeable.Bottom Line: Would you recommend this item? Yes
However they are fairly inexpensive so I have no regrets buying this.
