Astromania T2 T Ring and T Adapter Compatible for Canon EOS SLR/DSLR Camera | Black Anodized Aluminum,With Hex Wrench,Adapter Set-Mount Camera to Telescope,Achieve Astrophotography,12.3mm Optical Length

Great product and good quality

Fits snugly. Precision measurements for great fit. Sturdy construction, you can tighten retention screws without damaging lenses or stripping threads from the body. Adapter does not utilize focus as designed. Adapter is functional when using lense filters and does not prevent you from attaching a lens filter.

Mine out of the box was quite sloppy when attached to my camera. The problem was the tiny hex key set screws were too loose. To fix this you need a 1.5mm hex key to tighten down the screws. The hex key is not included. If the eyepiece spins too easily or wobbles that means those screws need to be tightened. As far as connection to camera body is fine, just line up the tiny red dot with the camera body white dot for lens attachment. Works fine on my D800e. The 1.5 hex key should have been included. Luckily I have a comprehensive set of sae and metric hex keys.

I have Canon DSLR professional cameras and this unit allows me to connect them to the telescope and take photos instead of using my mobil phone. The unit mounts to the cameras just like one of my lenses and slides easily into the Barlow 1.5inch holder.

Unit does not have any ridges for fixing screws to catch, it is a smooth cylinder and is only held by pressure where it attaches. Camera can fall if you loosen one of the screws, like mine did. I now have to replace the lcd screen on my Nikon

The construction of this products is pretty solid with it being all metal and no plastic. I bought this adapter because it was cheap and readily available. I attached this to a Nikon D3400 and the fit is perfect. There is no play whatsoever between the camera and the adaptor. This adapter then fit into my 1.25" adapter on my telescope with no fitting issues. With the lack of play from this adapter, I am comfortable with attaching this to other telescopes in different locations (on the telescope, depending on the telescope type). I also tried out some filters and the threads work out just like any other name brand product. Just know that depending on the telescope you have you my need an extension tube to focus, or you can use a barlow lens and be fine depending on what you are trying to shoot. Those crazy laws of physics :)

Good value, worked great on my 35mm Cameras, please school.

Great item fits well

Does what it says

Tried it out on the camera and telescope last night photo was crap but the TRing did its job.

Perfect fit for Nikon
