High precision 90mm refractor with 1000mm focal length

Checked 2026-09-10

This model increases the focal length to 1000mm while maintaining a 90mm aperture. The longer tube design is specifically intended to provide higher magnification levels for detailed planetary and lunar work. It uses a refractor design, which means the internal lenses are sealed away from dust and require very little adjustment over time.

A standout feature of this listing is the Vertisteel altazimuth mount base. This tripod is built to be more stable than standard aluminum versions, reducing the vibrations that can blur images at high power. The high-precision adjustment knobs allow for fine-tuning your position, making it easier to keep a moving star or planet centered in the field of view.

The package is rounded out with a phone adapter for basic astrophotography. This telescope is a good fit for adults who want a more substantial instrument for their backyard. The combination of the long focal length and the sturdy steel base makes it a specialized tool for those focusing on high-contrast views of the solar system.
