Description

Introducing the Stellarvue Optimus eyepiece series. This eyepiece is ideal for higher power work on planets and double stars since it is very sharp, contrasty and has an extreme 110 degree field of view. The 3.6 mm is ideal for those steady nights when you want to boost the power up on planets and observe fine details like the festoons on Jupiter. This eyepiece will do it while maintaining the high contrast that Stellarvue telescopes are known for. 

A 110 degree field of view provides the user with almost 2 times the area of an 82 degree eyepiece. When using hand driven alt-azimuth mounts this generous field will be appreciated. The eyepiece offers a generous 15 mm of eye relief and has a standard foldable rubber eye cup. Each of the eight elements are fully multi-coated, edge blackened and the lens barrel and baffles are similarly dark black. All of these factors add up to create an extremely contrasty eyepiece that is free of unwanted reflections, flaring or ghosting. 

We recommend this as the ideal higher power lunar, planetary and double star eyepiece.

Miles ★★★★★

That 110° field of view is just incredible for tracking Jupiter across the sky without constantly nudging the mount. The image stayed perfectly sharp right to the edge, even with my f/10 scope.

Edward ★★★★★

The 3.6mm focal length gives me enough magnification to resolve Cassini's division cleanly on Saturn. Sharpness right to the edge of that massive field really surprised me.

John J. ★★★★★

Was blown away by the 110 degree field on Jupiter last night—the view is incredibly sharp and contrasty, with none of the edge distortion I've seen in other eyepieces. Perfect for splitting tight double stars at high power.
