Tessaro Strata EQ mount, head only

Specifications

Description

The Strata EQ is a manual German equatorial mount for telescopes up to 6 kg. Once you align its polar axis with the celestial pole, you follow the sky by turning a single slow-motion control, which keeps planets and double stars centered at high magnification.

An equatorial mount tilts one axis to match your latitude, so it turns parallel to the rotation of the Earth. The Strata EQ has a latitude scale and an azimuth adjustment for rough polar alignment. Pointing the polar axis at Polaris, or at the south celestial pole region from the southern hemisphere, is accurate enough for visual use.

Slow-motion cables on the right ascension and declination axes allow fine control. The right ascension axis has a setting circle, and the declination axis has a scale, which help you find objects from their catalog coordinates once the mount is aligned.

The counterweight bar holds one 3.4 kg counterweight. Balancing the telescope against the counterweight before each session lets the mount move smoothly and reduces strain on the gears. The head weighs 4.6 kg and suits refractors up to 102 mm, Maksutovs up to 127 mm, and Newtonians up to 130 mm.

An equatorial mount takes longer to set up than an alt-az mount and positions the eyepiece in awkward places at some angles. Rotating the tube in its rings fixes most of those positions. Many observers find the tracking motion worth the extra effort, especially at high power.

The Strata EQ also teaches the basics of equatorial mounts, which helps if you later move to a GoTo equatorial mount for astrophotography. A clock-drive motor fits the right ascension axis for basic tracking.

About this configuration

This listing covers one configuration of the Tessaro Strata EQ mount, defined by its support, add-on, finish, and edition year. This configuration is the mount head alone, so you supply a tripod or a pier with a matching top plate. Buying the head only makes sense when you already own a sturdy tripod or a permanent pier in the garden. A weather cover suits observers who keep the mount outdoors on a pier or a covered patio.

The white finish stays cooler in sunshine, which helps if you set up the mount in the afternoon. The 2026 edition carries the mechanics over unchanged and updates small parts such as the knobs and covers. The payload rating in the specifications applies to the mount head in every configuration of the Strata line.
