Koolpte Vega Precision Ultra — 90mm / 900mm Refractor Telescope

Long-Focus 90mm Optics for Dedicated Moon and Planet Observers

Koolpte Vega Precision Ultra is the most detail-focused telescope in the Koolpte lineup. Its 90mm aperture, 900mm focal length, Fully Multi-Coated optics, three-eyepiece set, 90° Zenith Mirror, and micro-adjust controls are designed for beginners and growing hobbyists who want to spend more time studying the Moon, bright planets, and other rewarding night-sky targets.

90mm / 900mm Optical Design for Detailed Observation

The 90mm objective lens gathers more light than smaller beginner telescopes, while the longer 900mm focal length is especially well suited to lunar and planetary observation. Fully Multi-Coated optics help reduce unwanted reflections and support bright, high-contrast views.

Use Vega Precision Ultra to explore lunar craters and shadowed terrain, watch Jupiter’s bright moons, observe Saturn’s ring shape, and enjoy bright star clusters or selected deep-sky objects under darker skies.

Three Eyepieces + 3× Barlow Lens for Six Viewing Combinations

The included 20mm, 10mm, and 6mm eyepieces provide direct magnifications of 45×, 90×, and 150×. Add the 3× Barlow lens to expand your options to 135×, 270×, and up to 450×.

For the brightest and sharpest image, begin with low or medium magnification. Higher magnification is most useful when the telescope is carefully focused and the sky is especially steady.

90° Zenith Mirror for Comfortable Night-Sky Viewing

The 90° Zenith Mirror provides a more natural viewing angle when observing objects high in the sky. This makes longer Moon and planet sessions more comfortable and helps you stay focused on the details at the eyepiece.

Micro-Adjust Knobs for Fine Tracking

Micro-adjust knobs let you make smaller directional corrections as targets drift through your field of view. This added control is especially valuable when using higher magnification to study lunar features and bright planets.

Astro-Photo Kit and Precision Tool Kit Included

The Astro-Photo Kit includes a phone mount and Bluetooth remote for simple eyepiece photography. Attach a compatible smartphone, focus your target, and use the remote to capture photos with less screen-touch shake.

The included Precision Tool Kit supports telescope assembly and adjustment, helping you set up and fine-tune your observing station with confidence.

  • 90mm / 900mm FMC refractor telescope

  • 6mm eyepiece

  • 10mm eyepiece

Why Choose Vega Precision Ultra?

Clear skies, stable ground, and careful focus matter more than using the highest power first.

PRODUCT QUESTIONS

Frequently Asked Questions

Answers to common setup, delivery, returns, and warranty questions.

Yes. KOOLPTE telescopes are designed for beginners and are suitable for both adults and younger astronomy enthusiasts. We recommend that children use the telescope with adult supervision during setup and observation.

Depending on the telescope model and viewing conditions, you may observe lunar craters, bright planets, star clusters, and distant terrestrial objects. For the best first-time experience, start with the Moon using the lowest-power eyepiece.

Make sure the lens cap has been removed, then slowly adjust the focus knob until the image becomes clear. Start with the lowest-power eyepiece, as excessive magnification, poor weather, window glass, or atmospheric turbulence can make the image appear blurry.

Currently, KOOLPTE products are available for delivery within the United States only. Orders normally require 1-3 business days for processing and are generally delivered within 2-7 business days after shipment. Once your order ships, you will receive a confirmation email with tracking information.

KOOLPTE telescopes come with a 1-year warranty. You may also return an eligible product within 30 days of delivery, provided it is unused and remains in its original resalable condition. Refunds are issued after the returned item has been received and inspected; original shipping fees are non-refundable.
