Pros: Cons: Comments:I have been buying Baader accessories for many years and I have always found them to be of superior quality to others on the market. I know that if I buy a Baader accessory it will be much more than just satisfactory.

Dec 27, 2017Another fine Baader T2 item
Pros: Cons: Comments:Solid quality as we have come to expect from Baader and their T2 systems. This extension was required to add height to the 29mm Baader Budget 1.25" eyepiece holder. Certain eyepieces, most notably the Nagler 2-4 Zoom, have such long barrels that they contact the prism surface of the T2 Baader Zeiss prism diagonal part when used with that Baader EP holder.

Jun 19, 2017Baader Modular Extension Rings
Pros: Cons: Comments:Investing in rings, Change Locks and extension tubes can save you a lot of money on more eyepieces by varying your magnification intervals with a 1.25x, 2x or 3x barlow lens...in fact I only use one pair of excellent 25mm Zeiss eyepieces.

May 24, 2017Does the Job
Pros: Cons: Comments:Afocal projection for my revolution imager was easy with the purchase of this adapter, the /T-2 Budget Eyepiece Holder, and the T-Adapter HTA43/T2. Just screwed them on top of my Hyperion 17mm and popped in the video camera. Worked great for showing moon images at a star party.

Jun 26, 2015A helpful part...
Pros:No
Cons:No
Comments:I use several of these spacers (in two lengths) to achieve the proper back focus on one of my SCTs, in conjunction with a reducer/corrector. This, and the shorter spacer, working together, allowed me to achieve exactly the back focus I needed, and the total system works perfectly. Doesn't get any better than that.

Aug 8, 2013Nifty Extension Tube
Pros:Easy to Use,Compact

Aug 2, 2013Simple accessory that just works
Pros:Lightweight,Easy to Use,Accurate,Strong Construction
Cons: Comments:This is a basic, no frill item that provides the correct spacing for your T thread imaging train. The connections are solid and well machined. Although simple, these spacers have a very good "Bang for the buck".
Bottom Line: Would you recommend this item? Yes
If you need this type of spacer, look no further.This review was provided courtesy of AgenaAstro.com
