Mounts & eyepieces

Telescope mounts compared: alt-azimuth, Dobsonian, equatorial and GoTo mounts, polar alignment, payload capacity, tracking for imaging and star trackers.

Read telescope mount payload ratings, count the full imaging load and compare visual and astrophotography configurations before adding equipment.

Compare a Barlow lens and a shorter focal-length eyepiece for magnification, eye relief, cost, weight and your existing eyepieces.

Choose telescope eyepieces: low, medium and high power focal lengths, apparent and true field of view, exit pupil, eye relief for glasses, barrel sizes and Barlows.
