U.O. Orthos

Can anyone shed light on the U.O. orthos? I've heard them referred to as "Kasai", "Tanisawa", and "Kokusai Kohki". I tried the email address for KK on their site and it won't go through.

Thanks.

James,

If you're looking at buying some check out Helix Observing Accessories (on the main Astromart page). I bought two not too long ago and I love them. They're definitely a winner in my book. I haven't heard much about the new HD orthos but if they're as good as the regular ones then you won't be disappointed if you try them. And btw the people at Helix are a pleasure to deal with.
