Telescopes that changed astronomy

Amateur astronomy has come a long way from gazing at the stars with the naked eye to capturing stunning images of distant galaxies from our own backyards. Over the years, the tools of the trade, telescopes—have evolved alongside the passion of hobbyists, opening up the mysteries of the universe to anyone with curiosity and a clear sky. From early reflector designs to cutting-edge imaging systems, certain telescopes have revolutionized the way we explore the cosmos. In this blog, we’ll take a journey through the history of amateur astronomy and highlight the iconic telescopes that forever changed how we enjoy this timeless hobby. Whether you’re a seasoned stargazer or just starting out, these stories will remind you of the innovation and excitement that keep us all looking up.

Ed Ting reveals the 10 amateur telescopes that changed astronomy forever

Editor's note: Ed's coverage also appeared on the inside of our January 2025 issue. 

The first telescope on Ting's list is the Questar, a compact and elegant 3.5-inch Maksutov-Cassegrain telescope introduced in 1950. Ting emphasizes its transformative nature in an era dominated by bulky, DIY instruments.

Questar

Marketed as a precision-crafted piece, the Questar combined aesthetic appeal and portability, inspiring awe with its advertising campaigns. However, Ting humorously critiques the almost mystical reputation the telescope garnered, often exceeding the realistic capabilities of its optics.

Criterion Dynascope RV-6

Next, Ting discusses the Criterion Dynascope RV-6, a 6-inch reflector from the 1960s that became an icon of accessibility. Unlike the Questar, which catered to the affluent, the RV-6 offered an affordable, comprehensive package for amateur astronomers. Ting admires its durable optics and dependable mount, which made high-quality telescopes accessible to a broader audience. Decades later, these telescopes remain functional, a testament to their enduring quality.

The Celestron C8

Ting then turns to the Celestron C8, a telescope introduced in the 1970s that revolutionized Schmidt-Cassegrain design for amateur astronomers. The innovative use of affordable Schmidt corrector plates allowed Celestron to produce compact, versatile telescopes at a fraction of the price of competitors. The C8, Ting notes, is remarkably unchanged in its design even today, though its mounts have evolved significantly to incorporate modern technology.

Meade 2080

The 1980s brought the Meade 2080, a direct challenge to the dominance of Celestron’s C8. Ting recalls his initial skepticism, followed by admiration upon testing the 2080, which surpassed its Celestron counterpart in quality and performance. This telescope marked a bold move by Meade to disrupt the market, setting a precedent for fierce competition.

Meade LX200

Meade makes another appearance with the LX200, introduced in the 1990s. Ting describes this computerized telescope as a game-changer, offering amateur astronomers unprecedented ease of use. By integrating electronics into the telescope’s design, Meade empowered users to locate celestial objects effortlessly. While traditionalists criticized the decline of manual navigation, Ting praises the LX200 for its transformative impact.

Meade ETX90

Another milestone was the release of the Meade ETX90, a compact Maksutov-Cassegrain telescope. Launched alongside a groundbreaking advertising campaign, the ETX90 initially sparked high demand and even resales at inflated prices. However, Ting observes that the rise of the internet quickly exposed the telescope's limitations. Despite these flaws, the ETX90's influence is undeniable, signaling a shift toward aggressive marketing strategies within the industry.

Astro-Physics Traveler

The list continues with the Astro-Physics Traveler, a portable apochromatic refractor renowned for its optical quality and portability. Ting credits this telescope with setting a new standard for high-end refractors. While supply was limited, its influence on refractor design and the secondary market remains profound.

Stellacam

Ting also highlights the Stellacam, a low-light video camera that enabled real-time deep-sky imaging. Though not a traditional telescope, Ting argues its innovative use for amateur astronomers earns it a place on this list. The Stellacam transformed how faint objects were observed, paving the way for the integration of imaging technology in amateur astronomy.

Sky-Watcher Dobsonian

The penultimate entry is the Sky-Watcher Dobsonian, which Ting lauds for its affordability and user-friendly design. By offering large apertures at modest prices, Sky-Watcher democratized access to deep-sky observing. Ting credits these telescopes for introducing countless people to the joys of astronomy.

EAA Revolution Imager

Finally, Ting concludes with the EAA Revolution Imager, which represents the burgeoning field of electronically-assisted astronomy. This device exemplifies how technology continues to shape the future of amateur observing.

Throughout the video, Ting provides a mix of historical anecdotes, personal stories, and technical evaluations. While some telescopes stand out for their technical excellence, others earned their place through accessibility, innovation, or marketing. His engaging analysis celebrates the evolution of amateur astronomy while offering a thoughtful critique of its milestones.
