Product Info

Manufacturer Description

Standard 1.25" Prime Focus T-adapter fits on any telescope that uses a 1.25" eyepiece focuser for prime focus photography.

To use, insert the 1.25" barrel into your diagonal or telescope, attach your D/SLR camera to the male T-thread (via a T-ring that is specific to your camera; not included), and you are ready to take photos as prime focus with your telescope or spotting scope. In this set-up, the optical chain will be:

Telescope/Diagonal > Prime Focus T-adapter (this item) > T-ring > D/SLR camera

The 1.25" barrel of this adapter is threaded to accept standard 1.25" filters so you can use your favorite photography filters as well. Precision machined from aluminum and black anodized. The adapter weighs 0.9oz and its total length is 1.34" (34.1mm).

The use of this adapter is not limited to D/SLR cameras. It can also be used to image with webcams and video cameras. For this, you will need to attach your webcam to the male T-thread on the adapter via a webcam-to-T thread adapter. Similarly, you can connect a video camera via a C mount-to-T thread adapter. This adapter cannot be used with point-and-shoot cameras.

      5.0 Connect Nikon 1 - J5 to small Newtonian telescope

      Pros:

      Cons:

      Comments:

      Very nice, allows you to freely rotate the camera around to obtain the desired orientation rather than a straight screw on t ring connection which when snugged down arrives at a random orientation.

      Pros:

      Cons:

      The barrel of this T adapter allows me to mount my camera as close as possible to the eyepiece tube of my telescope and achieve prime focus without the use of a Barlow lens.

      5.0 Quality Product

      Pros:

      Strong Construction,Well Made,Lightweight,Easy to Use

      Cons:

      None

      Comments:

      This is a quality product. The camera adapter part exactly fitted my Nikon D80 and the part that fits into the telescope exactly fitted into my old scope. The only problem I had with it was tightening the screws on my scope to hold it into position. This is a problem with my scope NOT the adapter. This is a well made piece of equipment and great value for money.

      Easy to Use,Strong Construction,Lightweight,Accurate

      Cons:

      Comments:

      I purchased this to attach a USB filter wheel to my 2" focuser. I needed something simple that did not add to an existing back focus limitation. This adapter is well machined and anodized and works perfectly for my purposes.

      4.0 Superb, with a catch

      Pros:

      Easy to Use,Strong Construction,Compact,Lightweight

      Cons:

      Clearance

      Comments:

      I chose this T-thread adapter because it is nice and compact, without the unnecessarily long barrel of certain other T-thread adapters.

      The aluminum construction feels very strong, yet it is lightweight, and the black paint job looks very sharp. The paint hasn't flaked or peeled yet after a dozen uses. The threads mate with the T-ring threads precisely.

      One con for users of certain diagonals such as the one provided with Nexstar SE telescopes: the thumbscrews on these diagonals may not fully clear the flange of this t-thread adapter, preventing it from sitting flush against the diagonal.

      Pros:

      Compact,Easy to Use,Lightweight

      Cons:

      Comments:

      I knew I didn't have much back focus, so I chose this adapter. It works fine, but I was right about the back focus; I don't have enough, even with this piece, but it didn't cost much to find this out.

      Pros:

      Strong Construction,Compact

      Cons:

      Comments:

      I use this adapter with my DSLR camera for both Solar astrophotography (with my Coronado PST also bought here in AgenaAstro) and also, to use a difracting grid I got to get stellar spectra with my 8 inches reflector (also bought here :-) )

      It is simple, inexpensive and does its job well.

      5.0 Quality T-adapter

      Pros:

      Compact,Accurate,Strong Construction

      Cons:

      Comments:

      This adapter is professionally-made with excellent fit and function. I use this adapter for my Baader T-mount diagonal system (I previously had used only a 2" Baader T-nosepiece on the 2" diagonal). Now I can use my 2" diagonal in my refractors which only have a 1.25" focuser barrel. I suspect it would also work perfectly for prime-focus astrophography.

      Pros:

      Accurate,Strong Construction,Compact

      Cons:

      Comments:

      Anytime you use a telescope and want to preserve what you saw with your camera, you simply must have an adapter like this one. On my Meade 'scope, this inch and a quarter adapter slides nicely into my eyepiece tube, and with the matching ring to fit my Canon camera, lets me take pictures some people wouldn't believe.

      5.0 Just like an eyepiece

      Pros:

      Strong attachment

      Cons:

      Comments:

      This is all you need to connect any reflex camera (with their respective T ring) to any 1.25 focuser, I have use mine a lot, I like to take pictures of the moon on the focuser of my dobsonian, and the results are great.
      The chips of the modern cameras are so small that you do not need a 2"
