for connecting your digital camera to a telescope

The Photosolve Xtend-a-Scope 49T telescope adapter lets you attach your digital camera to your telescope.

The far side in this photo is threaded for standard T-mount (telescope mount) connections, while the near side incorporates 49mm threads for attachment to your camera or lens adapter. The Xtend-a-Scope 37T and 28T scope adapters are very similar but provide 37mm threading and 28mm threading respectively.

Using the Xtend-a-Scope 49T with an Xtend-a-Lens 4800, X04 or CLA-1 lens adapter (all of which have 43mm threads) requires the use of a 43m-to-49mm step up ring. The ring is placed between the Xtend-a-Scope 49T and the Xtend-a-Lens. You can connect from 37mm or 28mm lens threading using the Xtend-a-Scope 37T or 28T adapters instead.
