Sky-Watcher Variable Extension Eyepiece Projection Adapter (1.25\")

Use a variable extension eyepiece projection adapter anytime greater magnification is required for astrophotography. Ideal for shooting the Moon or planets.

Simply insert an eyepiece into the adapter, and screw on a T2 ring adapter (sold separately). Adapter accepts eyepieces 38mm outside diameter or less. May require an extension tube for long eyepieces.

The built-in telescopic extension makes it possible to use long eyepiece designs which tend to stick out of fixed-length projection adapters. Increasing the extension length also increases the projection power, while reducing the image brightness.

The 1.25" nosepiece detaches and is threaded to accept a T2 ring, so it can be used as a prime-focus adapter as well. Some Newtonian reflectors may require a 2x Barlow to reach focus when used in this fashion.
