Attaches Nikon F-mount SLR/DSLR cameras to telescopes Enables prime focus and eyepiece projection astrophotography Standard M42x0.75 female threads accept universal T-adapters Durable, all-metal construction ensures a secure connection Replaces the camera lens for direct optical train coupling Description FAQ Specifications In the Box Downloads Warranty Celestron T-Ring for Nikon Camera The Celestron T-Ring for Nikon cameras is the fundamental accessory for connecting your DSLR or SLR camera body to a telescope, turning your high-powered optics into a massive telephoto lens. This simple, rugged ring replaces your standard camera lens and provides the universal T-threads needed to connect to a range of telescope-specific adapters. This connection is the first and most critical link in the chain for capturing high-resolution images of the Moon, planets, and deep-sky objects, all backed by a 2-year warranty. The Essential First Step for Nikon Astrophotography If you own a Nikon camera, this T-Ring is the non-negotiable starting point for imaging through a telescope. It attaches directly to your camera's F-mount bayonet just like a lens, providing a secure, rigid platform. The interior of the ring features standard M42x0.75 threads, the universal interface for astronomy camera adapters. This threaded connection prevents the flexure, vignetting, and potential light leaks that can occur with less secure, universal camera mounts. By creating a solid metal-on-metal link, the Celestron T-Ring ensures your camera sensor remains perfectly aligned with the telescope's focal plane, a critical requirement for sharp, focused astrophotography. Connecting to SCTs, Refractors, and EdgeHD Systems Once the T-Ring is on your camera, you need a T-adapter to bridge the gap to your telescope's focuser or rear cell. The specific adapter depends entirely on your optical tube. Celestron offers dedicated adapters to ensure a perfect match and optimal image quality for various telescope designs. For Schmidt-Cassegrain Telescopes: The #93633-A T-Adapter threads directly onto the standard rear cell of most SCTs, making it the ideal choice for prime focus lunar and planetary imaging. For Refractors & Spotting Scopes: The Universal T-Adapter (#93625) features a 1.25” barrel, allowing you to slide your camera into any standard 1.25" focuser like an eyepiece. For EdgeHD Optical Systems: To maintain the flat field of an EdgeHD, specific adapters are required. Use the #93644 for the 8-inch EdgeHD or the #93646 for the 9.25-inch, 11-inch, and 14-inch models. What do I need besides the Celestron Nikon T-Ring to start astrophotography? The T-Ring is the first piece. You will also need a T-Adapter to connect the T-Ring to your specific telescope. The correct T-Adapter depends on your telescope's model (e.g., Schmidt-Cassegrain, Refractor, or EdgeHD). How do I attach the Celestron T-Ring to my Nikon camera? First, remove the lens from your Nikon camera body. Then, align the mounting indicator on the T-Ring with the one on your camera's body and twist it into place until it clicks, just as you would with a standard lens. Will this T-Ring work with any Nikon camera? This Celestron T-Ring is designed for Nikon SLR and DSLR cameras that use the Nikon F-mount. It is not compatible with Nikon's newer mirrorless Z-mount cameras, which require a different T-Ring. Can I use my eyepieces with the Celestron Nikon T-Ring attached? Not directly. This setup is for "prime focus" photography, where the telescope acts as the camera lens. To take pictures through an eyepiece (eyepiece projection), you would need an additional adapter, like a universal camera adapter that holds both the eyepiece and the camera. What's the best way to use the Nikon T-Ring to photograph the Moon with my 8" SCT? For an 8" Schmidt-Cassegrain, you would pair this Nikon T-Ring with the Celestron #93633-A T-Adapter. The T-Adapter screws onto the rear cell of your SCT, and the T-Ring on your camera then screws onto the T-Adapter. This setup positions your camera sensor at the telescope's focal plane for a crisp, high-magnification shot of the entire lunar disc. My telescope has a 1.25" focuser. Which adapter do I need for my Celestron Nikon T-Ring? For telescopes with a 1.25" focuser, such as many refractors or smaller reflectors, you should use the Celestron Universal T-Adapter (#93625). Its 1.25" barrel slides into the focuser, and your T-Ring/camera assembly then threads onto the back of the adapter.
