Ever since Galileo Galilei adapted a Dutch invention for astronomical use, astronomical telescope making has been an evolving discipline. Many astronomers after the time of Galileo built their own telescopes out of necessity, but the advent of amateurs in the field building telescopes for their own enjoyment and education seems to have come into prominence in the 20th century.
Tasco's telescopes have a reputation as entry-level equipment. [2] [3] It is one of several companies advertising their products based on claims of high magnification, far beyond any attainable usable magnification. [2] Tasco's telescopes tend to be referred to as "department store telescopes."
For instance, a telescope was referred to as a "geranium", which is a type of flower. A "potted geranium" referred to a telescope in a tube and rocker, while a "geranium in bloom" referred to a telescope whose mirror was now aluminized. [5] Eventually Dobson was given the option of ceasing his telescope building or leaving the order. He chose ...

When Edmund Scientific introduced the telescope in 1976 they called it "The Edmund Wide-Field Telescope" with a Part Number "2001" [5] Edmund had a public contest which ran until November 15, 1976, to come up with a name. [6] The winning name was "Astroscan 2001". The "2001" part of the name was dropped over time.

[1] [2] Ritchey was educated as a furniture maker. He coinvented the Ritchey–Chrétien (R–C) reflecting telescope along with Henri Chrétien. The R-C ...
The ads focused on the telescope's mechanical and optical design, educational value for children, ease of use, and adaptations as a spotting scope and telephoto lens. The Questar of the 1950s and early 1960s had a proprietary screw in eyepiece design and offered little capacity to employ third-party accessories.
