D & G OPTICAL is a full-time business devoted to offering the highest quality lenses and components at reasonable prices. All D & G OPTICAL lenses and mirrors are manufactured by us at our facility and are of the highest quality obtainable. We have recently tested, and in some cases corrected, poorly performing lenses and mirrors costing two and three times as much. Remember, high cost doesn't guarantee high quality. We feel certain you will be pleased with any optical or component purchase from us. If not, simply take advantage of our guarantee, which can be viewed in the “Terms of Sale” section of this website.

We, at D & G OPTICAL, were pleased to see the positive comments of Mr. Bob Matthews, owner of R. Matthews Optical Works in Seattle, WA. concerning an 8" objective lens, which was sent to him for testing by one of our customers.

His comments and a description of the completed telescope appeared in the Amateur Astronomers section, page 657, of the June 1989 issue of Sky and Telescope magazine.

Our pledge continues to offer the HIGHEST quality optics at reasonable prices. As always, should you have any questions concerning our products, feel free to call or write us anytime. We look forward to serving you.
