Hutech 5mm Orthoscopic Eyepiece
Absolutely the finest Broadband Multi-layer Coatings available have been applied to all surfaces. Reflectivity of less than 0.2% at each air-to-glass surface results in maximum contrast, light throughput, and freedom from ghost images. Or how about Superb Lens Polish? Hutech Orthoscopics are polished to a high standard for maximum clarity and contrast. A surprising number of premium commercial eyepieces suffer from roughness, excessive pits, or sleeks left in the lens surfaces. These tiny defects can hamper short focal length planetary eyepieces, where even the smallest imperfections scatter light and reduce contrast.

- Chrome plated barrels are threaded for standard 1.25" filters.

5 stars for optical performance, I have compared this eyepiece against an Orion Epic 5.1mm and a combination of 2.5 Televue powermate with 13mm Nagler T6 (resulting 5.2mm and the Hutech 5mm shows clearer and sharper images.
It shows great detail on my Unitron 75 f/16, on a friend Televue 76 (using a 2.5 powermate,and even more detail on a friend TMB 80mm f/6 apo Signature series, all at 240X!.
This is a great eyepiece.
The only downside is the little tiny hole where you observe, but I guess that is the price you pay to get the sharpest view.
It may be the sharpest eyepiece under $300.
I think I will buy also the 6&7mm.
