Varrow Lantern 130 Newtonian reflector, tube with equatorial mount

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

The Varrow Lantern 130 Newtonian reflector is offered in several configurations, and the notes below describe what this particular combination adds or changes. The equatorial mount follows the sky along one axis once you align its polar axis with the celestial pole. Balancing the tube and the counterweight before each session helps the equatorial mount move smoothly in both axes. Gloss white paint is easy to wipe clean, and the tube stays easy to spot in a dark yard.

The planetary kit adds a short focal length eyepiece and a set of color filters for the Moon and the bright planets. This is the 2023 edition of the Lantern line, the earliest version that is still listed in the catalog. If you plan to add accessories later, compare the compatibility notes with the parts you already own before choosing a configuration.
