Product Info

Manufacturer Description

This adapter allows you to attach 2" eyepieces and accessories to any equipment/adapter that has a male T thread (T2 mount). Common examples are telephoto lenses (which can be converted into excellent finder telescope with the use of this adapter, spacers, and an eyepiece), T thread adapters, off axis guiders, etc. Some Maksutov-Cassegrain telescopes use a male t-thread on their rear cell, so you can use this adapter as a 2" visual back for such scopes.

This high quality adapter has a standard T2 (m42x0.75) female thread on one end and a 2" eyepiece barrel on the other end. Eyepiece barrel features brass compression ring. Made of black anodized aluminum. Total length = 40mm. Inside depth of eyepiece holder = 35mm. Made in Taiwan.

      I needed this to add a coma corrector to a telescope that had a proprietary connection with a proprietary t adapter, but no 2 inch adapter and it worked perfect.

      4.0 Nice item

      Pros:

      Cons:

      Comments:

      The two inch cup could be a little deeper. Some eyepieces don't seat to their shoulder. Probably still fine but I'd like to see full penetration of the eyepiece.

      4.0 Excellent finish, but one thumbscrew

      Pros:

      Easy to Use,Compact,Lightweight,Strong Construction,Accurate

      Cons:

      Comments:

      I bought it to use with my Astro-tech field flattener (male m42), so I could put a 2" diagonal after that (and a bino).
      I regret it a bit, I would rather have bought the #C-01, with two thumbscrews instead of one, for only 3 dollars more, If I knew Agena had it for sale.
      But it was my mistake, I have to eat it up.

      5.0 Worked perfectly for my application

      Pros:

      Strong Construction

      Cons:

      None

      Comments:

      I bought this to replace the 1.25" EP holder attached to the blocking filter/diagonal on my Lunt 60 solar scope. Works perfectly. Allows me to use my 2" zoom EP with my solar scope and maintains compatibility with the 2" focuser on my astro scope.

      5.0 Works well with 2" eyepieces

      Pros:

      Lightweight,Accurate,Easy to Use,Strong Construction,Compact

      Cons:

      Comments:

      I am using this in combination with a Baader Vixen M43 Female to T2 Male Adapter (#T2-22 1508037). I removed the original 1.25" visual back and diagonal from the refractor. I replaced the visual back with the M43/T2 adapter. The T2/Eyepiece holder threads on the the M43/T2 adapter.

      This accessory holds my 2" eyepieces firmly. The 21mm, 13mm, and 8mm show no vignetting. Only my 35mm Kellner shows some minor vignetting at the edge of field.
