  • Description: 

I bought this part to attach to my planetary scope, but I found out after buying it that I could not use it in my set up, which is very much "space restricted" (see in PICTURES OF MY SETUP), so it has been resting for a 3 or 4 years now in a pelican case!)

It allows to have a guider scope AND an additional "upper" port in your optical train. With this device, you can get 3 optical pathes out of your existing viewing port:
1) 2" Normal viewing "straight port" (as the one you have).
2) 1,25" Guiding port (it has a little mirror that can be precisely adjusted for a guiding camera).
3) 2" "Up port", that allows you to use another camera or an eyepiece there (you slide a big 45º mirror "in" ("up port" usage) or "out" ("straight through port" usage))

Given the out-of-business nature of manufacturer, I am selling this superb adapter at a higher price than original price. But market rules. Please, SEND IN YOUR OFFERS IN CASE YOU ARE INTERESTED.

  • A WARNING WORD HEREMy descriptions are faithful. If I say an optic is clean, then it is clean. I am NOT a cold Corporation thinking up just in numbers and my selling here is a long term responsability activity. I want you to be sure you are paying for what I am describing. In fact, most of my items are over-described (I tend to look specifically for problems instead of overlooking them). If for some reason you think I missed it up, get back to me. I don't tend to mess around with people. Like most of you, I work out my life with others "Quid Pro Quo" style, which means that I TRY TO DO OTHERS WHAT I WOULD LIKE THEM TO DO WITH ME.
