Celestron 93625 Universal 1.25-inch Camera T-Adapter, Single

For my Powerseeker 70az was looking for a TAdoper and T-Ring to go with my Canon EOS D-600. Enquirers with camera accessory dealers turned out to be non-productive. Decided to try this. and it works like magic. You would need a TRing to go with this. I would say a must have accessory if you are a nightwatcher and own a DSLR

Nice attachment.

This is a quality product from Celestron - goes about doing its job perfectly, i.e., sits nice and square between your telescope and your camera. All metal and along with T-ring, this is the one that keeps your camera hanging on to the telescope.The package from Amazon was good - although the bubble-wrap further wrapped in celo-tape cocooned the product very well from any kind of bashing during the shipping, it's slightly messy to unwrap (need multiple cuts using sharp knife - on the bubble-wrap of course).

Good product, works as required

It is as good as you expect from Celestron.

This product is unnecessary and it's unfortunate that it's being sold by the name of Celestron. All you need is a t-ring which allows the camera threads to sit on the Celestron scope. Don't buy this. No issues with the seller as they are usually unaware of this.

Very poor quality and performance

Purchased along with T ring. Could not focus after attaching camera to telescope. Could focus after replacing this with my 2x Barlow lens from telescope kit.

El dispositivo debe ser adquirido junto con el anillo en T para la cámara específica que se tenga. Para el caso de un telescopio Celestron Astromaster 130 es importante mencionar que no se logrará hacer un enfoque con una cámara DSLR o SLR a foco primario (la cámara sin objetivo conectada directa al telescopio con el adaptador universal y el anillo T), ya que hace falta distancia para lograr el enfoque con la recámara de enfoque del telescopio.Una solución es conseguir adicional el Adaptador T universal Barlow modelo 93640. Aunque se tendrá el doble de aumento, es posible lograr el enfoque de la imagen.

At first I thought it only works with Celestion scopes because the focal plane is closer than I could get with this and the canon ring. I have a case with a bunch of Celestion lenses that all work wonderfully. So I didn’t imagine this not working. Off to the forums I go, where I learned that I should try the Barlow lens with it. That works great. Only thing, it is probably close to a 2000 mm equivalent and that is a very small field of view, and hard to keep steady. Must use timer or remote.

I guess the designer of this product wanted, for some reason, to allow eyepieces to be used inside it. Or perhaps a barlow lens. But the result is an adapter that is longer than it needs to be, and that moves the camera more than an inch farther than necessary from the image plane of the telescope's primary optic. This makes the adapter unusable with most Newtonian reflectors built for visual use: the film/sensor plane of the camera can't be brought close enough to the objective to bring an image into focus. Even on a refractor of catadioptric telescope, the length of the adapter needlessly increases torque around the point where the focusing tube enters the focuser. I'm not sure whether Amazon carries any, but there are low-profile adapters that minimize this effect, and are better for most prime-focus astrophotography.UPDATE: After using this product for almost a year, I've decided that it warrants one more star than I gave it at first. The product has held up very well in fairly heavy use. I've also found that the space inside the adapter is more useful than I initially realized. I did have to purchase a shorter adapter from another source to get my camera sensor to prime focus of my Newtonian's primary mirror without a Barlow lens. But since I do have a "shorty" Barlow from which the lens can be separated, I have found that slipping that separated Barlow element into the empty space in this adapter, and securing it there with the setscrew, does make for a nice, moderately amplified image. Amazon does also sell a similar Celestron product,  Celestron T Adapter/Barlow 1.25 Universal (Req. T-Ring) that puts a Barlow at the front of what appears to be this same adapter. All things being equal, however, a Barlow lens closer to the focal plane of the camera causes less amplification, requiring less of an increase in exposure (and hence less tracking accuracy).

works good and good quality except a little bit pricy
