Comments about Pentax SMC XO Telescope Eyepieces:

While many will use this eyepiece for detecting fine lunar and planetary detail, I have used this ocular in a 15 inch reflector to resolve challenging multiple stars and for detecting extremely faint galaxies. Both of these operations require very high light transmission and excellent contrast. Recently, I was pleased to see Saturn's Cassini Division with this eyepiece.

I have field tested the Pentax 5mm XO against another high end 5mm EP (albeit one with a wider field of view)--the Pentax was the clear winner each time.

This eyepiece is considered the gold standard at its focal length by many discriminating observers--I can see why!

Highly recommended.
