Description "High-hat" model The "high-hat" adapter is specially designed with a high rise head to keep TeleVue Barlows and Powermate™ amplifiers away from the diagonal mirror. "In-Travel" model This 2" to 1¼" adapter allows more in-travel for 1¼" eyepieces than our "flat-top" or "high-hat" adapters. This adapter is designed to attach to the 1¼" eyepiece barrel and convert the eyepiece for use with a 2" focuser or diagonal. The main application is for 1¼" eyepieces that may need more in-travel due to limited focuser range of your telescope. "Flat-top" model A flat-top model allows closer placement of the eyepiece. Use with Newtonian reflectors, Tele Vue Paracorr, 2" Powermate and 2" Big Barlow. "Equalizer" model A heavy solid bronze version called the "Equalizer" adds 12-ounces to help equalize the weight when switching from heavy 2" eyepieces to light 1¼" eyepieces. Features exclusive anti-reflection angle that prevents reflection back to the objective.
