Portable 70mm Refractor Telescope

The Celestron 21035 is a 70mm aperture refractor telescope designed for beginners and casual observers. It uses fully-coated glass optics and ships with a full-height tripod, a custom backpack, and a download code for astronomy software. The package includes 20mm and 10mm eyepieces for low and high-power viewing.

Setup Requirements

The optical tube measures 18 inches deep by 7 inches wide by 14 inches high and weighs 3.3 pounds. Manual focus adjustment is used for all observations. A reflex finderscope assists with aiming at celestial or terrestrial targets. No tools are required for assembly according to the supplier.

Best For Casual Beginners

This telescope suits users wanting a lightweight, grab-and-go system for backyard astronomy and daytime spotting. Buyers who need a larger aperture for deep-sky detail or a computerised GoTo mount for automated tracking should consider other options. The refractor design limits light grasp compared to larger reflectors.

The box includes a 70mm refractor tube, 20mm and 10mm eyepieces, a reflex finderscope, a full-height tripod and a custom backpack. No extra purchases are required for basic observing.

Should I choose the 70mm model or the smaller 50mm version for brighter views?

The 70mm aperture gathers more light than the 50mm model, giving brighter and more detailed images while adding very little extra weight.

The 20mm eyepiece provides low-power views and the 10mm eyepiece provides high-power views for both celestial and daytime land-based observing.
