Tasco (also known as Tasco Worldwide) is a major international distributor of telescopes. Tasco mainly makes telescopes for amateur astronomers but has expanded into other optical products such as spotting scopes, microscopes, binoculars, and telescopic sights and other rifle accessories. Tasco sells via specialty outlets, catalogues, and online retailers.

Tasco is based in Miramar, Florida. George Rosenfield founded the firm as the Tanross Supply Company in 1954. It started as a distributor of fishing tackle and hardware. The name was later shortened to Tasco as inventory expanded to include binoculars and eyepieces.[1]


Tasco manufactures both a variety of optical equipment including terrestrial telescopes, microscopes, binoculars, telescopic sights, and accessories for each.

Three categories of telescopes are available from Tasco - Novice, Luminova, and Spacestation. Each family has several models. The Novice family features the most economical telescopes using manual focus and view finding, while the high end Spacestation utilizes fully automated sky-mapping, "GoTo" technology. Magnification ranges of the telescopes are advertised as between 25 and 675 power.[2] Both reflecting telescopes and refracting telescopes are available in each category.

Tasco's astronomical telescopes have a noted poor reputation as a usable instrument.[3][4] It is one of several companies that follows the deceptive practice of advertising their products based on claims of high magnification, far beyond any attainable usable magnification.[3] Tasco's astronomical products usually get lumped in with the whole series of telescopes pejoratively referred to as "department store telescopes", low quality and low cost instruments targeted at the impulse purchase market.[3][5][6]


Tasco makes binoculars with magnifications range between seven and ten power on a variety of models. They also offer Snapshot series binoculars, which include an ability to record video and capture still pictures as seen through the binoculars. Users can transfer images to a computer through a USB cable. Tasco provides software for viewing and printing.

Gun sights[edit]

Tasco makes telescopic sights for long rifles, rimfire rifles, and handguns featuring magnifications of 1 to 40 power. They also make non-magnifying red dot sights.

Terrestrial scopes[edit]

Tasco offers several models of spotting scopes. These scopes are designed for rugged outdoor use and feature rubber armour protection as well as optional camouflage. Models have magnifications between 12 and 45 times, and feature panoramic view finding.

Company history[edit]

Tasco was founded and owned by George Rosenfield in 1954. In March 1996, Rosenfield sold the business. At that time, Tasco employed 160 people at its Florida headquarters, and maintained a location in the state of Washington, which employed 40.[1] In June 1998, Tasco purchased Celestron, another telescope manufacturer which focused on performance optical equipment and the more serious observer. Celestron was second only to Meade Instruments Corporation in sales of telescopes.[7]

Early 2001, Tasco began searching for a buyer as profits sank. Meade Corporation begins negotiations for a merger, but the Federal Trade Commission blocked the attempt.

By June 2002, Wind Point Partners, parent company of Bushnell Performance Optics (BPO) purchased the Tasco brand and all the company's intellectual property.

In July 2007, Wind Point Partners sold Bushnell Performance Optics along with Tasco property and sales rights to MidOcean Partners, a private equity firm based in New York and London.[8]


On May 29, 2002, Tasco Worldwide initiated liquidation of all its assets.[9] after defaulting on nearly $30 million in loans.[10] The company had been searching for a buyer for several months, but after much interest by Meade Corporation, the Federal Trade Commission, on this day, sanctioned a temporary restraining order in federal district court to preempt any attempt by Meade Instruments Corporation, the leading manufacturer of performance telescopes in the United States, to purchase all, or certain assets, of Tasco Holdings, Inc. including Celestron, a child-company and number two performance telescope provider in the U.S. The FTC argued that an acquisition by Meade of Celestron would negatively impact the performance telescope market by eliminating significant competition between the two companies and by creating a monopoly in the market for Schmidt-Cassegrain telescopes, which were currently only being sold in the U.S. by Celestron and Meade.[7]

In response to the FTC’s denial, Meade filed several lawsuits against both Tasco and Celestron concerning a patent for a “Fully Automated Telescope System With Distributed Intelligence,” also known as “GoTo” technology, charging the two companies with patent infringement and unfair competition. The complaints were filed in the United States District Court, Central District of California, Southern Division, but were all subsequently denied.

Later in 2002, Tasco and Celestron, now under the ownership of Bushnell Performance Optics, fired back with lawsuits also in the District Court of California, alleging Meade products infringed on a United States patent entitled "Tripod Structure for Telescopes." Both companies sought injunctive relief and compensatory damages in an unspecified amount, and attorneys' fees and costs. In December 2002, the District Court denied both Celestron's and Tasco’s motion .[11]
