Product Info
Manufacturer Description
This popular eyepiece adapter allows 1.25" eyepieces and accessories to be used in 2" focusers, diagonals and barlows. It includes a brass compression ring that restrains the eyepiece and prevents marring of the eyepiece barrel by the metal set-screw. It is precision machined from aluminum and anodized black.
With an optical length of only 4mm, this adapter will give you some additional in-focus travel compared to standard 2"-to-1.25" eyepiece adapters. It might be just what you need to bring an eyepiece to focus in your telescope.
Threaded to accept standard 48mm filters so you can use your 1.25" eyepieces with your 2" filters (be careful not to let the eyepiece barrel hit the filter though).
Specifications:
- Total height = 1.1" (28mm)
- Optical length = 0.16" (4mm)
- Weight = 3.1oz
Important: The thumbscrew on this model is on the side of the adapter body (see photos), so it is perfect for use with "low profile" focusers that have a side notch to accept this screw. Otherwise, you will not be able to slide this adapter completely inside a focuser as the thumbscrew will get in the way of complete insertion.

Oct 17, 2014Excellent product
Pros:Very Good Fit And Finish
Cons:None
Comments:I bought this adapter for my Mak-Cass. Fit in the scope is excellent, as is the fit of the diagonal into the adapter. Nice touch is the non-marring compression ring. Holds diagonal with heavy binoviewer securely. Finish is nicely polished and black annodized. Excellent product, as with all other Blue Fireball adapters and extensions that I have bought.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com
Mar 22, 2013Blue FireBall Low Profile Adapter
Pros:Strong Construction
Cons: Comments:If you need a little more in focus travel this adapter can provide that. But keep in mind the eyepiece locking screw position may be inconvenient.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com
Mar 22, 2013Made to work even better
Pros:Easy to Use,Strong Construction,Compact
Cons: Comments:I needed a very low profile 2" to 1.25" adapter and this fit the bill. I achieved an even lower profile by replacing the side screw with a set screw. Worked great and gave me more of a focusing range.

Feb 25, 2012Well made adapter
Pros:Lightweight,Pressure ring is nice,Strong Construction
Cons: Comments:Tre pressure ring, tightened by the screw, is much nicer than just a screw by itself. This prevents marring the eyepiece.
Bottom Line: Would you recommend this item? Yes
The adapter does protrude a bit on focusers that don't have a cut out for the tension screw (like my Celestron focuser).
This can make the adapter a little unstable. I often use mine without the tension screw so it seats better.This review was provided courtesy of AgenaAstro.com
Feb 11, 2010Inexpensive solution for 1.25" to 2"
Pros:Strong Construction
Cons: Comments:I bought two of these adapters to go with the GSO Superview 15mm and 20mm eyepieces.
Bottom Line: Would you recommend this item? Yes
By keeping the adapters permanently attached to each, it allows me to quickly change between eyepieces all using the native 2" GSO mirror diagonal.
If you want to make the step-up from 1.25" to 2" optics, this is a good way of reusing your older eyepieces with a minimum of hassle.
Note that this is a low-profile adapter, so to use this in a 2" diagonal that diagonal to have a notch for the retaining screw.
If your diagonal doesn't have such a notch, you can easily replace the thumbscrew with a grub-screw from local hardware store, for semi-permanent attachment.This review was provided courtesy of AgenaAstro.com
