Discovery Telescopes 8" f/7 Premium DHQ (PDHQ) Dobsonian Telescope

When you talk about a Discovery Dobsonian Telescope, you aren't just talking about any run-of-the-mill, mass-produced dob... You're talking hand-figured quality and all American pride in workmanship. When you lay your hands on a Discovery, you'll discover what you've been missing.

All Discovery Dobs include the finest hand-figured optics available today and are custom made-to-order. Discovery optics are manufactured in their own state-of-the-art facility, not sold out of the country to the lowest bidder. Every set of optics is painstakingly tested until it passes Discovery's strict standards for "diffraction limited". They incorporate the use of Fizuea, Equal-plate and Scatter-path interferometers and documentation can be provided for your telescope for an extra fee.

You won't find any shortcuts or substandard parts in a Discovery Telescope. There are no design flaws. Every Discovery Dobsonian Telescope is fully assembled and checked for fit and finish before it ever leaves for shipment. All of their telescopes are handcrafted and masterfully built. You will never find a Discovery Telescope sold in a discount department store... Ever!

Will you pay a little more for a Discovery Dob? Yes. But you won't have to pay for extras that should be part of a standard package. All Discovery Dobsonian Telescopes come with a 2" Crayford focuser with 1.25" adapter, dust cover and Telrad viewfinder..

Ask a Question
  • Can the single speed crayford focuser handle the weight of a 2.7 lb load from a heavy eyepiece and barlow/accessory by focusing without backlash?

    This focuser holds 4 pounds. Please call with any questions.

  • which material is used for primary mirror , is it pyrex glass or soda lime glass ?

    Discovery does not specify, but they have usually used soda lime glass for 10" and smaller mirrors in the past.

  • can I buy digital setting circles and a computer for this scope?  Approximate cost?

    JMI does not have the specific measurements for the Discovery 8" Dobsonian, but a DSC computer and encoders could be purchased for approximately $500-900 depending on the database of the computer (~200 objects at the low end and ~40,000 at the high end).
