Telescope Camera Adapter, T2 T Ring and T Adapter M42x0.75 Male Thread to 1.25 Inches Telescope Photo Adapter, T-Mount Telescope Astrophotography Accessories for Canon EOS SLR/DSLR Camera

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 :)

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.

Very sturdy construction, feels machined and anodized, no issues with it and pictures came out great

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

Not Quite Right. . I can get it on, but it takes some wiggling. I finally bought one from directly from Agena Astro and it works perfectly, so I studied them carefully to see what the difference was. I found that the two (lets call them) "retaining clips" that grasp onto the camera were placed about 5 mm too close to the red dot so that it was almost impossible to screw it onto the camera. I ground off about 5 mm of each of the retaining clips and it works perfectly now. In the pictures the Agena Astro ring is on the bottom, and this Astromania is on top. Blue tape with an ink mark shows where the retaining clip begins on the Agena Astro T adapter, and where it should be on this one, and a little blue tape sticking to the inside shows where it actually starts on this T adapter. The difference is about 5 mm. In the second photo with the rings on top of each other, you can see the shiny spots where I ground off about 5 mm from the two rings closest to the red dot. If you are having trouble getting this ring to attach, get out the Dremel and carefully grind off a little off the retaining clips.

Great item fits well

I havent had a chance to use this yet because of all the storms, but hopefully I'll get some good pictures to post here in a few days.

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
