Televue 2" to 1.25" Flat Top Adapter
Do you need to step down your 2" focuser or star diagonal to accept your 1.25" eyepieces? In certain telescope styles such as SCTs, or catadioptrics, there's only a minimal amount of clearance when the eyepiece swings through the drive base and clearance can become an issue. That's why Televue created the Flat Top Adapter.
This low profile adapter is designed to provide a shorter light path than the standard TeleVue adapter and provides extra clearance. What's more, the Televue Flat Top Adapter also has a special safety groove machine right in. This deep channel allows the focuser thumbsrew to act as an extra safety guard and reduces the chance of the adapter falling out of the focuser should the thumbscrew loosen. But that's not all... You value your eyepieces and so does Televue. The Flat Top Adapter incorporates a non-marring soft brass clamp ring instead of a thumbscrew to keep your eyepiece barrels looking like new. It's also fixed internally so it can't fall out of the adapter. Good news for those of us who have spent one too many observing nights searching through the grass for a dropped set screw! Back that with a five year manufacturer warranty and you see the Televue Flat Top Adapter is quality through and through.
Televue Product Number: ACF-2125
NOTE: If you have a Newtonian reflector, or plan to use the Tele Vue Paracorr, 2" Powermate or 2" Big Barlow, you will benefit from the "Flat-Top" Adapter, which allows closer placement of the eyepiece.
