Varrow Lantern 130 Newtonian reflector, tube only

Specifications

Description

The Lantern 130 is a Newtonian reflector built around a 130 mm parabolic primary mirror with a focal length of 650 mm. Working at f/5, it gives a moderate field with low-power eyepieces and reaches higher magnifications on the Moon, Jupiter, and Saturn when paired with shorter focal length eyepieces. The primary carries an aluminized reflective coating with a protective overcoat, and a flat secondary mirror on a four-vane spider directs the light to the focuser on the side of the tube.

Because the optical tube is open at the front, it reaches outdoor temperature more slowly than a small refractor, so allow twenty to thirty minutes before you attempt high-power planetary work. Collimation matters more on a Newtonian than on a refractor. The mirrors leave the factory aligned, but shipping and handling can shift them, and you can adjust the three collimation screws on the secondary cell with the supplied Allen key. A simple laser collimator makes this job quicker and more repeatable.

The 1.25 in dual-speed rack-and-pinion focuser holds standard eyepieces and a basic star diagonal. At 6.8 kg for the tube, the Lantern 130 needs a sturdy equatorial head or a stable alt-az mount with a broad base. The 6x30 finderscope helps you locate targets before you move to the eyepiece.

Typical targets include the craters along the lunar terminator, the cloud bands of Jupiter, and the rings of Saturn at high power. Under dark skies, you can also find brighter Messier objects such as the Orion Nebula, the Hercules Cluster, and the Andromeda Galaxy, which show more structure at this aperture than at smaller sizes.

About this configuration

This listing covers one specific configuration of the Varrow Lantern 130 Newtonian reflector, defined by its bundle, finish, accessory kit, and edition year. This is the optical tube on its own, so you need to supply a mount that can carry its weight steadily. Buying the tube alone makes sense if you already own a suitable mount or plan to choose one separately. Carbon fiber saves some weight compared with a metal tube, which eases the load on the mount and on your arms.

The starter kit adds two eyepieces and a Barlow lens, which gives you four magnifications from three pieces. The 2026 edition carries the optics over unchanged and updates small parts such as dust caps and thumbscrews. If you plan to add accessories later, compare the compatibility notes with the parts you already own before choosing a configuration.
