- *(Quick Tip 1: No mirrorless here, folks. Remember to flick off that DSLR autofocus and fine-tune your spotting scope's focus knob for those jaw-dropping, crystal-clear shots.)*
- *(Quick Tip 2: The bundled T-Ring won't snug up to full-frame cameras. If you're eyeing a full-frame connection, you'll need to snag a separate T-Ring crafted specifically for those beasts.)*
**How to Use:**
STEP 1
- First, connect the end of the camera mount with an M42 thread to the T-ring.
STEP 2
- Next, attach the T-ring with its M42 thread to your SLR camera.
STEP 3
- Then, connect the camera-mounted support to the eyepiece of your spotting scope. Use the plastic screw on the camera mount to secure it to the eyepiece.
- Finally, turn on your camera and disable the autofocus feature. Use the focusing knob on the spotting scope to get a clear image for shooting. Your spotting scope can now serve as a telephoto lens for your DSLR.

I have used these before for my telescope with a Nikon camera, but It took me a while to find the correct adapter for my canon camera. This was the perfect solution, and it fits well. You will need a t-adapter to use this T-ring with SCT telescopes, but I already had one. They come with the m43 threads just like a vintage lens, and all you need to do is screw them together. I have used this adapter both with my 5d mkiii and my eos R (with ef-rf adapter) cameras, and it works perfectly for both. You could also use this to adapt vintage lenses to modern bodies, but my main focus was astronomy. This adapter is made of metal, so the materials are up to my standards. You get everything you want at a price you can afford.

Easy application, but the lense is open so be careful with use, especially for higher end cameras

This M42 T-ring adapter is a solid choice for anyone getting into astrophotography with a Nikon camera. Right out of the box, it attached smoothly to both the camera and telescope without any issues. The fit is secure, with no alignment problems or light leaks.Build quality is excellent—this adapter feels sturdy and well-made, with no flimsy parts or loose connections. When in use, it maintains sharp image quality without any distortions. Focusing was smooth, and I had no trouble dialing in a crisp image.For beginners looking to connect their Nikon to a telescope, this adapter delivers exactly what it promises. It’s easy to use, well-constructed, and performs reliably. Given its quality, the price feels like a great value. If you’re just starting out in astrophotography, this is a smart addition to your setup.

Starboosa M42 T-RingGood build and fits perfectly on a Nikon D5600. Worked great with a gifted T-adapter on an older telescope. No issues with the threading, making mounting super easy. It comes wrapped in a simple white cardboard box and has a red alignment mark on the ring. Three evenly spaced screws around the mount keep it secured to the threads, and an Allen wrench is included for adjustments.Note: The "T" in T-mount stands for Tamron. They devised the system in the 1950s-1960s to sell their lenses to fit other makes of camera bodies.

This Canon T-ring is beautifully machined and fits my Canon 5D Mark II DSLR, and my Celestron T-adapter perfectly.If you have a telescope that uses 1.25” eyepieces, you can use this T-ring, along with a T-adapter, to attach your Canon DSLR to your telescope.Just remove the lens from your Canon DSLR, and replace it with this T-ring. It even has the red dot to help you align it. Next, attach a T-adapter, which you need to purchase separately. I use a Celestron T-adapter meant for a Schmidt Cassegrain telescope. (See pictures). Finally, remove the 1.25” eyepiece from your telescope, and insert this set-up in place of the eyepiece.Now your telescope is basically a giant telephoto lens for your camera. You can get wonderful pictures of the Moon, and take videos of planets, which can later be stacked, for terrific images.Note that T-rings are .made for specific brands of DSLR, whereas a T-adapter should work with any T-ring.

If you have a spotting scope or telescope already, this is a great bit of kit. It is well-made and fits easily onto my Cannon DSLR. Whilst not cheap, it is pretty good value for money, as a separate camera lens would cost a lot more.The screw in fittings make this very versatile.It might be obvious, but tripods are a must.

This adapter feels well made and lightweight. It is constructed from aluminium alloy and has some plastic screws which initially I was dubious about but they seem to get a good grip and work well with my Celestron scope.It’s a good alternative if you don’t have a telephoto lens and makes better use of a spotting scope or telescope.It’s a snug fit, and is a nice useful addition to my bag.In my opinion it’s fairly priced, ideal for wildlife, cityscapes, and the like.I hope you find my review helpful.

In theory, this is a great product, but there are a few issues. First, it does not quite fit my older (20+years) mid-level Kowa Scope. It is just a few millimeters too short at its full extension to grip the eyepiece above and below the rotating zoom ring. I can still turn the zoom, but it's tough and the locking screws drag on the knurled part of the zoom ring. Second, and more importantly, it has a bit of wobble when connected wither to my EOS7DmkII or my EOS 5DmkIV. This results in considerable wobble when adjusting the view or even when taking the shot. I set the camera on 10 second delay to allow it to settle down before shooting, but you need a patient bird for that, and even then the mirror slap would prevent you from taking a quick series of images. Third, you have to be sure the mount is exactly centered on the eyepiece or you get a round glare across part of the image (see photos). Supposedly you cannot use the adapter on full-frame cameras. Here's the deal on that. It works on the 5D, which is full-framed, but you see some vignetting at the corners; this is worse at low zoom (20x on my scope) and id gone at higher zoom (60x). The worst of it could easily be cropped out. On the 7D with a crop sensor it's fine since the corners of the image coming from the scope fall outside the sensor area, i.e. it's cropped off in the camera. In the photos you can see the adapter, a image of pine needles showing the streaking, 2 images of ornaments, one showing vignetting, and a picture of a bird. I had to use high ISO's (cloudy day) and the resulting images had a lot of noise, so these are all processed with camera RAW and then with Topaz to sharpen and reduce noise.
