iOptron designed the 80mm f/5 Achro Refractor Telescope with an achromatic doublet lens system that is fully multicoated to produce bright and sharp high-contrast images with accurate color rendition across a distortion-free field of view. The relatively short focal length makes it ideal as an easy grab-and-go option or for use as a guide scope on a larger OTA; while producing a fast focal ratio, which makes it ideal for imaging the sun (with proper solar filters installed), moon, and planets.
With the two included eyepieces offering low and moderate magnifications, plus the addition of an erect-image diagonal, this scope can be used as a traditional terrestrial spotting scope as well as for astronomical observations. The scope is offered here without a mount or tripod, but a Vixen-style dovetail plate is provided for compatibility with a wide variety of mounts.

- Achromatic lens configuration virtually eliminates chromatic and spherical aberration to produce images with accurate color rendition without distortion across the entire field of view, especially at the edges
- Anti-reflection fully multicoated optics improve light transmission, image brightness, sharpness, color rendition, and contrast
- Resolution: 1.4 arcsec
- 1.25" rack-and-pinion focuser
- OTA only, mount and tripod required for proper use
- Vixen-style dovetail plate<
- Weight: 2.2 pounds
- Eyepieces:
- 1.25" diameter barrel accepts most astronomical filters
- 10mm focal length produces a moderate 40x power
- 25mm focal length produces a low 16x magnification
- Diagonal:
- 1.25" snout fits most drawtubes and accessories
- 1.25" holder allows the use of most eyepieces and accessories
- 45° angle puts head in a comfortable viewing position when OTA is aimed at or near the zenith
- Integrated erecting prism corrects the view to allow the scope's use as a terrestrial spotting scope
