T-adapters can turn your telescope into an amazing telephoto lens and this one will work with any that have a 1.25" visual back. This piece has a 1.25" inserting slip connector which replaces the Star Diagonal on your telescope and the title given by Celestron is entirely misleading, it refers to a generic measurement of an inch (actually 1.25"). The faulty description continues in the product description: it WILL NOT FIT .96" visual backed telescopes such as the Celestron C90, or the Nexstar 4GT. In that case you'll need this part Celestron 93635-A T-Adapter for NexStar 4GT Those telescopes have a .96" visual back and the T-adapter has a female ring which screws over the visual back.

In either case you still need a T-Ring to connect to your camera, be careful there too as there are now ones for 58mm digital cameras that are larger than the older 35mm.

Getting Amazon to change these descriptions is difficult so hopefully this review can correct it.

The description for this product does not mention that using this T adapater will not allow the camera to focus on many Newtonian reflectors because the adapter basically extends the focuser and will not allow it to travel in far enough to achieve focus with the camera.

There are a few fixes for this. First, check the focuser on the scope to see if the eyepiece holder will unscrew and allow you to screw the camera's adapter directly to it. If not, you can purchase a 2x barlow (Celestron item # 93640) that includes a T-adaptor on it or a zoom lens with threads for a filter that will also allow you to directly attach your camera adapter such as Celestron's 8mm - 24mm item # 93230. Obviously, including a lens in the equation magnifies the image which you may or may not want.

The most expensive and intrusive is to replace the focuser with an aftermarket focuser that will allow this to work.

Other than the fact that it was not directly compatible with my scope, the quality of the T adapter was very good which is typical for Celestron products.

So I was having the same issue that the other people with poor ratings were stating, couldn't get the telescope and camera to focus. Basically waiting for a non-cloudy night where I could see the moon, something to focus on. 1st attempt I hooked it up, but could not get the moon to focus. Thought that I couldn't get everything to go close enough. Then I tried it one night without the camera just the adapter and the telescope, realized that it needed a lens in the adapter. Now was figuring how is this going to work. That's what the little screw on the side is for, to hold a lens in the neck of the adapter. Also however my lens inside the adapter makes the lens protrude inside the camera body. So I didn't end up screwing the adapter fully onto the t-mount. Just enough to get it to hold. Then pictures galore. Simple product just a tube to allow you to attach the camera to the telescope, like the option of changing lenses as this lets me have different magnification shots of the sky.

I ordered the Celestron 93625 Universal 1.25-inch Camera T-Adapter for use on a Celestron C90. It works as advertised and I am pleased with the photographs I have gotten with this combination. Some of the reviews suggested it does not work on this model of telescope. The proper mounting of the item on a Celestron C90 requires the use of the erect image diagonal included with the telescope. After my success I am presuming others were expecting the adapter to fit directly to the optical tube which requires the Celestron 93635-A T-Adapter for NexStar 4GT instead. The adapter seems to be solid and supports my heavy Canon 5D well.

This product screws into the T-ring and hooks to my Canon Rebel-XTI as expected. The product attaches to my telescope as expected. Unforunately, I could not focus as is. The telescope required adjusting the mirror position to perfect the focus. So I learned something. Connected to a Tasco Luminova telescope.

I got this working with my Orion XT8 Dobsonian. But you need some more things with this. Of course you'll need a T-mount/ring to attach to the camera. I bought the Opteka mount for my Olympus E-500. You'll also need to add a barlow lens to the end of the adapter or else you won't be able to focus. Celestron has a package that bundles the adapter and barlow together if you don't already have a barlow.

Highly recommend this as a cheap way to venture into astrophotography.

Once you realize that you have to put a lens inside this before you attach it to your camera, it works great! If you didn't realize that, or didn't realize that there should be directions included (Gee, there's a concept), than you would think this is a horrible investment. Now that I figured out I needed to put a lens in there before attaching it to my camera, I'm very happy!

Bought this to use with the "EzFoto T/T2 Mount Lens to Nikon" and they match up perfectly.

Using this for a Nikon D3200.

Build quality is very good.

Using this product with a tall telescope eyepiece is a little cumbersome, but I knew this before ordering.

My 5mm eyepiece fits without any issues. 12.5mm eyepiece fits when I screw out the T Mount about half of the thread length and the 25mm eyepiece just barely clears the camera's mirror when I screw the T Mount all the way out and leave about a half a turn of thread to hold onto the T Adapter.

So overall, it functions very well for what I intended to use it for!

My first impression is that this is a sturdy, well-built piece. The main purpose of this review is to let other potential buyers know that it is, in fact, threaded for use with filters. I wanted to use a skyglow filter with my dslr and schmidt cassegrain telescope. Threads are nice and smooth for both the filters and the t-ring. Focusing the SCT with the rear cell adapter and even a f/6.3 focal reducer was fine. So, I anticipate no focus problems with this.

Of course you're going to need a T-ring (specific to your camera's model) in addition to this T-adapter so that you can connect your camera to a telescope. Another really important feature is to get a counterweight kit so that your camera's weight doesn't throw off the alignment of your telescope's motor. Works fine on my Celestron Nextar 8SE.
