Your cart is empty.This sturdy, high-quality adapter provides a solid connection between your Schmidt-Cassegrain or Maksutov-Cassegrain telescope and 2” accessories without any special threaded 2" diagonal. This accessory makes it possible to maximize your views through your telescope with your standard 2” diagonal, eyepieces, and other accessories (like photo adapters) allowing you to connect a camera for astroimaging. The adapter offers an ultra-secure threaded connection to your telescope. On the other side, a brass compression ring provides a strong grip on eyepieces accessories without scratching or denting their barrels. To tighten the ring around the accessory, just adjust the set screw. With its precision machined aluminum construction and black anodized finish, this adapter will resist corrosion and wear, providing you with years of use. The black interior also reduces the internal light reflections, enhancing your view.

hoping to turn a one and a quarter inch image train into a 2 inch image train on my XLT Omni 127. It worked.This fits in place of the visual back and allows a 2†image train

It can replace 1.25" back and allow use of 2" eyepieces.

Wow arrived allready, even before says was delivered. Well built and soild. One issue I have had is I have a Williams 2" diagonal and was very tight getting in. Think thr copper ring has a slight issue, but got the diagional in.Not such a big concern to drop down a star.Very good quality.

I have used a Tele Vue 2" SCT adapter for a couple of years. Tele Vue's adapter has two clamping screws that secure against a brass ring to hold diagonals or other items that are inserted. Celestron's adapter is nearly identical, but has one clamping screw that secures against a brass ring, but it holds everything securely. I attached the adapter to a 9.25†SCT tube, then inserted a 2†extender and tightened the clamp screw. I was able to lift and shake the scope just holding on to the extender; the assembly was very tight and did not move or loosen at all. The Celestron adapter is also less than half of the price of Tele Vue's adapter. I suppose that Astromania, Gosky, or Solomark might have similar adapters for less, but I have had issues with some of the brass compression ring technology on some of the devices offered, and Celestron has a great return/replace policy, even if you didn't buy directly from them. It was worth the extra $2 for the unneeded replacement policy.

Wer mit dem Planetenjäger ein weites Feld für Deep Sky erzielen möchte, sollte sich einen 2" Adapter an den Tubus schrauben und mit einem 32mm 2"Okular beobachten. Das macht das Gerät schon fast zu einem Allrounder. Der Adapter passt hervorragend und ich hatte den Eulenhaufen in der Kassiopeia mittig im 32er Okular nadelscharf stehen, Wunderbar. Dieser hier passte anstandslos.

I attach a Sony a6500 to my Celestron C5, and the 1.25" visual back is just "okay". This converts the visual back to a 2" and it now feels as sturdy as a Hulk. Worth it, in my opinion.

It fits right on my 30+ year old C5 Spotter.The compression ring is nice too.You will have to provide your own 2" to 1.25" adapter.
