What do you do when you have a 2" diagonal and most of your eyepieces are 1.25"?  Get yourself a 2" to 1.25" adapter! This inexpensive diagonal adapter simply slides into the barrel of the diagonal and locks in place.  Instead of a 2" opening, you now have a 1.25" opening, complete with thumbscrew for securing your eyepiece into the adapter.  Problem solved. 

Besides common diagonal adapters, the Diagonal & Eyepiece Accessories category holds replacement (or add-on) eyeguards for your eyepieces, eyepiece trays that attach to your telescope or mount...a kind of eyepiece butler, if you will, and even Tele Vue's Dioptrx adapters, which allow folks who suffer from astigmatism to choose their glasses prescription and correct the view through an eyepiece!
