Excellent condition. Superb planetary & galaxy views. High-quality PYREX mirror. Limited use. Kept in 1st floor room.

Selling because have too many scopes…

Selling it for less than the shipped Discovery price, yet you get over $400 worth of extras!


1. PYREX mirror.

Helps viewing in cold. Gives good images faster than plate glass.

2. Enhanced coatings (94%), for brighter images.

3. 2" Crayford focuser with 1.25" adapter.

JMI—DX-3, metal, high quality—smooth precise. Better than rack and pinion, especially in colder weather.

Mirror center spotted, but holds collimation well.

Manual, original boxes. No eyepiece.

Pick up only, Binghamton, NY. Avoid shipping delays & problems (& auction site bidding wars).

Only $680. Bank check or U.S. postal money order.

OPTIONAL: have scope be digital setting circle ready.

For only $100 more, I will reinstall the Discovery mounting brackets and provide the U.S. Robotics encoders, Discovery tangent arms, and cable (worth $160 shipped & saves you installation trouble). All you need is a DSC computer box. Works well with Sky Commander and standard DSCs from Celestron, JMI, Lumicon, etc.
