Can't seem to find a 28mm Pretoria eyepiece, tried AM etc. Anyone got one for sale or know of any leads??
Also, need a 90 reflection/ 10 transmission beamsplitter about 20 x 20mm will pay or swap for a 50/50 type.

I know you want a ready made beamsplitter, but if you ever want beamsplitters, etc to make a custom device, there are often good toys to play with at www.surplushed.com (http://www.surplushed.com)

Their address is actually www.surplusshed.com (http://www.surplusshed.com) ( note two s's) Use them all the time, fanatastic collection of bits and excellent service. Highly recommended.

Does anyone have/ use the Pretoria? Love to hear a comparison between say a Nagler/ Wide view on a 10 - 12" fast telescope ( <f5)

So far so good ( But I think the Captain of the Titanic said the same thing about 11:23pm!!)
Does ANYONE have a Pretoria eyepiece??? I've tried unsuccessfully on AM etc but I'd love to hear from someone who has experience using it on a fast (<f5) system. The original write up in ATM mag makes it sound like it really is the answer to a maiden's prayer.
Any comments.
