Discovery Telescopes 15" f/5 Premium DHQ (PDHQ) Split-Tube 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 Split Tube 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 Split Tube 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 Split Tube Dobsonian Telescopes come with a 2" Crayford focuser with 1.25" adapter, dust cover and Telrad viewfinder.

Ask a Question
  • What is the height of the EP at zenith?

    The EP height at zenith is approximately the same as the focal length with Discovery scopes, so that would place it at ~75"

  • Can Discovery telescopes be purchased without the Split-Tube Design(solid tube.)

    Hello, All PDHQ scopes 10" and up are a 2-piece "Split-Tube" design. Anything less than 10" will be solid. We may be able to special order a solid tube version, but the shipping costs would be higher due to the tube's length. Please contact us if you ha

  • Are the split tube Dobs made of metal or Sonotube?   Could the 15" be ordered with a curved vane spider?

    The split tube dobs have sonotube tubes with metal brackets on the outside. Bill at Discovery says that he can substitute a curved spider at no additional cost if specified at time of order with OPT.

  • Can Discovery telescopes be purchased in Canada

    Yes, although there is no free shipping outside the lower 48 contiguous US states so a shipping quote would need to be figured. Please call us if you have any additional questions.
