Sky-Watcher 80mm f/7.5 Refractor

The Sky-Watcher Evostar 80EDX Limited Edition is an 80mm f/7.5 doublet apochromatic refractor telescope. It uses FPL-53 ED glass with Metallic High-Transmission Coatings to deliver true-color, high-contrast views for visual astronomy and astrophotography. The optical tube features a white metal-flake aluminum finish and internal baffles to suppress stray light.

Ideal for visual observers and imagers

This telescope suits astronomers who want a lightweight apochromatic platform for both visual use and deep-sky imaging. The 2.8" dual-speed Crayford focuser provides 1:11 fine-focus control for precise adjustments. Buyers who need a triplet design for the highest color correction or a larger aperture for significantly fainter objects should consider other configurations.

24% more light than 72ED models

The 80mm aperture gathers 24% more light than 72ED variants, revealing fainter details and improving image brightness across all targets. This single specification determines whether the instrument meets your depth requirements for visual observation or exposure times for photography. The f/7.5 focal ratio balances field of view and focal length for versatile performance.

Questions about this item

What focal ratio does the f/7.5 doublet lens cap for astrophotography exposure times?

The f/7.5 focal ratio sets a moderate speed that balances wide-field framing with manageable exposure lengths for deep-sky imaging.

What tube diameter and focuser size must the mount and accessories clear?

The 80mm aperture tube and 2.8-inch Crayford focuser dictate the clearances needed for rings, dovetail plates and camera adapters.

How is the 1:11 dual-speed focuser calibrated, and which knob do users confuse?

Rotate the coarse knob for rough focus, then engage the fine-focus knob for the 1:11 micro-adjustment; users often skip the fine knob and overshoot sharpness.
