BAADER CLICKLOCK 2INCH /T2 Adapter #2956242

[paulastro]

I purchased this to be able to use my new Celestron Ultima Edge FF 2inch fit, 30mm 70 deg eyepiece with my Baader T2 90 deg BBHS Prism #2456095.  

As all Baader equipment I have ever used, it works perfectly.  Firm grip, easy to use and no vignetting at the edge of the field.  Even better, I think it looks cool too 😅.

The scope in the pics is my Altair Starwave 80 ED-R fpl53 doublet, on a Scopetech Zero altaz

Price for 2” T2 adaptor is?

It's £86. Quite a lot, but nothing will ever come detached from it when you don't want it to 🙂.

Thanks Paul. I ordered mine yesterday as you know, but some sneaky, inconsiderate person bought the last one only minutes before. Anyhow, mine is due to arrive sometime next week. 😁

Sorry Mike.  If I'd known you wanted one, I would have stepped aside, and let you buy it.  🤣

What is the clear aperture of the BBHS prism Paul? Is it the 34mm one? and you say there is no vignetting with the 2" 70deg eyepiece, do you know the field stop diameter? Lovely set up!

Franklin, here is details of the prism, from Baaders info sheets.

The field stop diameter of the 30mm is 30.4mm.  That's correct, no vignetting with the Celestron 30mm Ultima Edge FF 2inch 70 degree eyepiece.

Thanks for that Paul. I have the basic T2- 32mm Baader prism and with my 30mm 2" there is a touch of vignetting, not much but it's there, and I've just realized the 32mm is the prism size, it's clear aperture is more like 28mm so that explains it. Shall have to start saving for one of the larger Zeiss spec prisms!

You're welcome Franklin.  I'd suggest you look out for a used prism, but alas they don't come along very often, I think people tend to keep hold of them.  The best of luck to you.
