Televue 1.25"/2" 3.7 Ethos-SX Eyepiece


Televue 1.25"/2" 3.7 Ethos-SX Eyepiece

This is a PRE-ORDER product. The price is based on R8.60/$ and an international selling price of $650.00.

With 110°, the Ethos-SX has 21% more AFOV area than the 100° Ethos design. This permits a nice 62% power increase from a 6mm Ethos, while retaining 68% of its TFOV. The 3.7mm actually has more TFOV than our 8mm Plössl, 6mm Radian, and 5mm Nagler Type-6!

While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element. The field area of this new eyepiece is more than 50% larger than an 82º field.
