Review CELESTRON C90 1000mm Maksutov Telescope S/n

Celestron C90 Maksutov-Cassegrain Telescope (Model: 912963, Serial Number: 910566)

The Celestron C90 Maksutov-Cassegrain Telescope is an exceptional instrument for amateur astronomers and stargazers, offering impressive performance and versatility in a compact and portable design. With a primary mirror of 90mm (3.54 inches) and an f/13 focal ratio, this telescope delivers crisp, high-contrast images of celestial objects.

At the heart of this telescope lies a high-quality Maksutov-Cassegrain optical design. This innovative combination of a short focal length spherical primary mirror and a hyperbolic secondary mirror provides excellent image correction, ensuring that stars appear as point sources and planets exhibit their intricate details. The Maksutov design also results in a shorter effective focal length, making the telescope more comfortable to use for visual observation and easier to align for astrophotography.

The Celestron C90 comes with a 1.25" Crayford-style focuser, which offers smooth, precise focus adjustments and has enough backfocus length to accommodate a range of accessories, such as Barlow lenses, eyepieces, and imaging cameras. The telescope tube is constructed from lightweight, yet robust aluminum, and the optical tube length is a manageable 41.7 inches (1,060mm), making it easy to transport and set up in various locations.

Additional features of this Celestron telescope include a collimation cap, which simplifies the process of aligning the mirrors, and a sturdy Vixen-style dovetail mounting plate, enabling easy attachment to various mounts and tripods. The telescope also includes a StarBright X-Lite Dual Speed Crayford focuser, which offers a broad focus range and fine focus adjustments for optimal image quality.

In summary, the Celestron C90 Maksutov-Cassegrain Telescope (Model: 912963, Serial Number: 910566) is a powerful and versatile instrument for astronomical observation and astrophotography. Its compact design, excellent optical performance, and user-friendly features make it an ideal choice for both beginners and experienced amateurs, offering a gateway to a world of celestial wonders.
