I got this as a gift with a bunch of astronomy stuff. It looks like a telecompressor.
Very well made. No identifying marks at all. It just smells like a Astro-Physics product, but I cannot tell for sure.
Threads do not fit my ED-80. Large lens side is 2 3/4 inches at the threads. Small lens side is 1 7/8 inches. It comes apart as shown in the photo's.
Any guess??? It is probably a product of the late 80's early 90's judging by the other stuff. It was just in a box.
Red cap plug says ED-40 on it. Also has number NAS-813-40. I am NOT certain that this belongs with the item.
I have a couple more pictures on the classified site.
Thanks...all guess are welcome and will be treated with respect.
