Severe Vignetting for 35mm Full Frame Cameras
By Technology Guy
The Celestron 93635-A T-Adapter connects the rear cell of a NexStar 4 or C90 scope to a T-ring (sold seperately) which is designed to fit your specific camera. There isn't much to the adapter -- just a threaded metal tube with a metal screw-on ring on one end. Note that you will need to use your camera in fully manual mode though the camera's internal light meter will probably function normally allowing you to set the shutter speed for a proper exposure during daylight hours.
While the T-Adapter does function as advertised, it suffers from a design flaw -- the connecting tube is too narrow causing severe vignetting (i.e., the corners of phtots are cut off and appear very dark or black) at least for a 35mm full frame camera mounted to a C90. I have not tried it with a C-sized digital camera yet. Due to the severity of vignetting, you might want to consider an alternative model of T-Adapter or, better yet, a Tele-Extender designed for Schmidt-Cassegrain telescopes such as the Orion 1.25" Standard Tele-Extender which can be used in place of a T-adapter on the C90, doesn't suffer from these sever vignetting problems and is much more versatile.
Note: A tele-extender is similar to the T-adapter but is designed to optionally allow you to place a telescope eyepiece inside - between the scope and the camera - for even higher magnification. For example, with the T-adapter, a C90 can function as a 1200mm manual camera lens. With a tele-extender, it can do the same or, by adding a 18mm eyepiece, act as a 5000mm or greater lens.

Perfect. Better than expected
By Jeff®
I got this to mount my Sony á300 to my Celestron C-130 Mak. It is just perfect for prime focus. I expected it was going to be plastic like the crappy 45° visual back eyepiece holder Celestron supplied, but it is a very well made black anodized machined aluminum piece. The camera is mounted to the scope like a rock. (A big heavy rock LOL). For less than $25 and the second to none service from Adorama, you can't go wrong.

Celestron T-adapter
By W. Dyer
This T-adapter allows your film or digital SLR to attach to your telescope and take photographs. It is well constructed and easy to use. You will also need an adapter that fits on you camera, the two then link together. This adapter does not allow autofocus, but it didn't claim to do so. You focus via the focus device on your telescope.
