  • Attaches to a variety of camera adapters and accessories via standard T-Threads

Description

A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you. To use the Canon EOS T-Ring, remove the lens from your camera, and attach the T-Ring in its place, just as you would if you were mounting a lens. The telescope side of the T-Ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do. You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The 93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor, the Universal T-Adapter (93625), with its 1-1/4” barrel insert, is available. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (93644) and one for the 9.25, 11, and 14-inch EdgeHD (93646). Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you need extra magnification beyond that which your Schmidt- Cassegrain telescope provides, a Tele-Extender (93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.

  • Works perfectly
This is a solid T-Ring that screws into to a Canon EOS camera on one end in place of a lens. You then screw a 1.25" camera t-adapter into the t-ring and voila, you can begin your journey in astrophotography. The item is metallic and feels very solid and attaches to the camera just like a lens would. It takes seconds to attach and detach and is well worth the cost of entry. Highly recommend! ... show more

  • Exactly what I needed to adapt an inherited lens to my Canon EF bodies
I inherited a 500 mm telephoto lens that was set up for a Pentax K mount via an adapter. The native mount on the lens is T mount, i.e. M42x0.75. I simply unscrewed the K mount adapter and substituted this one. Super easy.

  • Dust off those old lenses!!!
I have an old old Spiratone 400mm lens that was fitted with a T-Mount for my old old Minolta SRT-101. It had been kicking around for ages and recently I thought "whoa ... T-Mount, I wonder?". Fact is that this little gem of a mount mates the thing to my Canon EOS. It took some fiddling to get setting right ... you set the aperture and the camera sets the shutter speed. If you read manuals, which I refuse to do, you would have been up an running in seconds. It took me minutes. The picture of the palm tree is from about 400 feet away, hand held. Seems to me that this opens up a world of cheap thrills, old lenses at flea markets and on ebay abound. Anyway, I am very satisfied. Buy one and fool around. ... show more

  • Fit on a Canon EOS T7i and a telescopic lens with T connector.
The adapter inner ring was loose. It requires an Allen Wrench (1.25mm) to tighten the 4 set screws. I was able to tighten 3 of 4. I think the 4th set screw is missing. It works fine with the screws tighten. There is an extra ring which does not fit on to the camera. It may be another adapter ring that is not described on the product. There is no documentation. I kept the adapter as it is working with my old telescopic lens. ... show more

  • i can only say -- it is the best
before buying this ring i was afraid that it will not be made from good materials specially after reading some reviews saying that it dont have the ability to lock on the body of the camera ... what i received whas really a great product and together with the Celestron t-adaptor that i ordered it is doing the job in perfect way...the ring is locking well in the body but you have first to insert it in the right way like the EF lens there is a small hole in the side of the ring that it should face the red dot in the body of canon camera then whenyou turn the ring clockwise it will lock witout any problem.. my camera is Canon600D my telescope is Celestron skyprodigy 130 . The only problem is that i am not able to focus the image even after removing the ring and the t-adapter nd the eye piece holder from the telescope focuser the focal point in my telescope is still far away from the sensor of my Canon .. i knew from the begining that it will happen and that can be resolved by placing a Barlow lens between the telescope and my camera but as i am still waiting my barlow lens to be released from the customs i cannot give you a full rview but if your telescope is montinned to be an astrophotography scope this is the best and chippest t-ring to get from the market dont hesitate ... show more

  • Sweet Piece
The item is exactly what you see in the picture. Straight forward, simple and it has a demarcated spot just like a lens to make installation easy and not have to guess or play with it as you install it on your camera and potentially damaging a sensor. You want to connect your EF Canon to your telescope? You need this. Made out of metal so it’s durable. Highly recommend it. ... show more
