Koolpte Vega Precision Ultra 90mm Aperture 900mm Refractor Telescope
Vega Precision Ultra 90mm / 900mm Refractor Telescope
Koolpte Vega Precision Ultra is the most detail-focused refractor in the Vega lineup. Its 90mm aperture, long 900mm focal length, FMC optics, three-eyepiece set, 90° zenith mirror, and micro-adjust controls are designed for serious beginners and growing hobbyists who want to spend more time studying the Moon and bright planets.
90mm / 900mm Long-Focus Optical Design
The 90mm objective lens gathers more light than smaller beginner refractors, while the 900mm focal length is especially well suited to detailed lunar and planetary observation. FMC optics help improve light transmission and contrast for clearer views.
Three Eyepieces with a 3× Barlow Lens
The included 20mm, 10mm, and 6mm eyepieces provide 45×, 90×, and 150× magnification. The 3× Barlow lens expands the available combinations to 135×, 270×, and a theoretical maximum of 450×. Practical usable magnification depends on target brightness, focus, atmospheric stability, and viewing conditions.
90° Zenith Mirror for Comfortable Night-Sky Viewing
The 90° zenith mirror provides a natural viewing angle when the telescope is pointed higher in the sky, making longer Moon and planet sessions more comfortable.
Micro-Adjust Controls for Fine Positioning
Micro-adjust controls help you make smaller directional corrections as a target moves through the field of view. This added control is especially useful during higher-magnification observation.
Smartphone Photography and Included Tools
The included smartphone adapter and wireless remote support simple eyepiece photography with less shake from touching the phone. A precision tool kit is also included for telescope setup and adjustment.

Questions beginners ask before buying
What is the Vega Precision Ultra 90/900 best for?
Its long 900mm focal length and 90mm aperture make it especially well suited to repeated Moon and bright-planet observation.
Is 450× the normal magnification I should use?
No. 450× is the theoretical combination produced by the 6mm eyepiece and 3× Barlow. Practical usable magnification is often much lower and depends on target brightness, focus, atmospheric stability, and seeing conditions.
Which eyepiece should I start with?
Start with the 20mm eyepiece at 45×. Once the target is centered and sharp, move to 90× or 150× as conditions allow.
What do the micro-adjust controls do?
They help you make smaller directional corrections while observing, which is especially useful when higher magnification narrows the field of view.
Can I take photos with my phone?
Yes. Use the included smartphone adapter and wireless remote. The Moon is the easiest target to practice with first.
