The A81M is an achromatic refractor with 81 mm objective lenses.
It has a focal length of 910 mm with an aperture ratio of 1:11.2.
The long aperture ratio produces pure-coloured, high-contrast images for an achromat.

With this telescope, you can obtain impressive views of the moon, planets and bright deep-sky objects.

The telescope is built according to stringent Japanese quality standards and high-quality workmanship.

The telescope also comes with a folding mirror for making observations in unfavourable conditions, as well as a T2 thread for connecting a DSLR camera.
