One of the best planetary eyepieces around for only $50.00?
Tis true! See my write up on weatherman dot com, here is an excerpt:
"I recently (June, 2001) had the opportunity to match the 4mm UO
orthoscopic against fierce competitors.. the 4mm Radian (televue),
the 3.8mm Pentax XP, and the Takahashi 4mm
Hi-Ortho. The hi-ortho had the best eye relief, and the XP was
perhaps ever so slightly better, the Televue had more off axis
color. Overall, the 4mm UO ortho is the best buy! Detail on Mars
was fabulous using a 6" Takahashi."
By the way it is MINT. It is a 1.25" eyepiece with threads
for filters. Unbelievable on Mars, as I indicated on the page
$50.00 plus $5 shipping, or nice trade.
