M48 is quickly becoming the more popular choice for thread size on telescopes and accessories as it can accommodate up to Full Frame size camera sensors without any vignetting like T-threads/M42. M48, on the other hand, is a slightly wider thread, hence why you may see the term Wide T-Ring. This size T-Ring is most common, and can accommodate up to APS-C size DSLR and Mirrorless cameras. However, many manufacturers often interchange the two labels, and it's generally safe to assume that T-Rings that say M42 will thread into T-threads.

Technically, T-threads have M42 x 0.75 threads and pitch, whereas M42 threads are M42 x 1. This is usually listed in the specifications or manual. You'll need to find out which size threads the telescope/accessory you're trying to attach your camera to has before deciding on a T-Ring. First are T-Threads, which are 42mm in diameter, and second is M48, which is 48mm wide. There are two main sizes of threads featured on the telescope side of T-Rings. What do T-Threads (M42) and M48 (Wide) mean?

To be sure, check the specifications or manual for your specific telescope/accessory you're trying to attach your camera to. If you're using an optical accessory like a focal reducer, it may also have standard threads to attach a T-Ring already. Do I Need A T-Adapter if I Have A Focal Reducer or Other Accessory? T-Adapters are often specific to your telescope, so be sure you get the right one. In most cases, you will need both a T-Adapter and a T-Ring to be able to attach your DSLR or Mirrorless camera to your telescope. A handful of telescopes, however, come with the right threads to attach a T-Ring already on the back so you don't need a T-Adapter. What Is A T-Adapter?Ī T-Adapter is a device that adapts the telescope side connection to threads you can attach accessories to on the camera side. On the other side, it is threaded to attach to a telescope or accessory behind a telescope, which are usually T-threads or M48. A T-Ring is a simple adapter that allows you to connect your camera to a telescope or accessory to do astrophotography. On one side, it has a bayonet mount to match your specific camera, just like a lens would attach to.
