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.
Discovery Telescopes 15" f/5 Truss Tube Dobsonian Telescope
All Discovery Truss 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 Truss 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 Truss Tube Dobsonian Telescopes come with a 2" Crayford focuser with 1.25" adapter, primary and secondary mirror dust cover (not cheap plastic, either), your choice of 7x50mm or Telrad viewfinder, a rip-stop nylon light shroud, aluminum eyepiece shelf and a truss pole bag.

- Questions & Answers
Product QuestionsHi, Thanks for your time. I've recently acquired this exact model. I t came how ever without eye pieces. It was suggested that I acquire 2 lenses to begin with but three would be even better. I was advised to use only 2" lenses, #1 32-36mm #2 12-17mm and #3 22-27 and also advised to stay with in these sizes for each lens and try to acquire lenses >80 degree AFOV and with at least 20mm of eye relief. I am on a fixed low income due to disabilities, this being the situation and $$ being scarce what suggestion as to brands and lenses would you suggest I purchase for use with this f5 Discovery15" Newtonian reflector Dobsonian. What filter/filters should I make notes of acquiring for this scope also. Thanks again for your efforts and time. Sincerely: Jamie TQuestion by: Jamie Tollefson on Feb 11, 2017 1:29:00 AMThose are good focal lengths for your eyepieces, but if you have long eye relief and wide fields, there is really no need to make every eyepiece a 2" version - it will be more expensive for no real benefit. Your lowest power eyepiece will usually be 2", but the medium and high powered eyepieces work fine if they are 1.25" Take a look at the Explore Scientific or Celestron 82 degree eyepieces, and l would recommend that you look into a UHC filter for nebulae and a neutral density filter for the moon.Answer by: Chris Hendren (Admin) on Feb 15, 2017 4:33:00 PM
