Corvane Ardent 114 reflector, tube with GoTo mount

Specifications

Description

The Ardent 114 is a compact Newtonian reflector with a 114 mm parabolic primary mirror and a focal length of 500 mm. At f/4.4 the short tube gives wide low-power views, which makes it easy to find objects and to frame large star clusters and bright nebulae.

The parabolic mirror matters at this fast focal ratio. A spherical mirror of the same size and focal length would blur stars across the field, while the parabolic surface brings them to a sharp point in the center. The secondary mirror is held by a thin four-vane spider, which produces the familiar small diffraction spikes on bright stars.

A Newtonian needs occasional collimation, the alignment of its two mirrors. The Ardent 114 has adjustment screws on both mirrors and a center spot on the primary, so you can check and adjust alignment in a few minutes with a simple collimation cap. Fast reflectors are sensitive to alignment, so it pays to check it before each session.

The short 500 mm tube weighs 2.9 kg and fits on the back seat of a car. With 114 mm of aperture, it collects about 2.6 times as much light as a 70 mm refractor. That extra light helps with globular clusters such as M13, the Ring Nebula, and the brighter galaxies such as M81 and M82 under suburban skies.

The short focal length limits high-power views, so planetary detail calls for a short focal length eyepiece or a Barlow lens. At around 100x, Saturn shows its rings clearly and Jupiter shows its main belts, as long as the air is steady and the mirror has cooled.

About this configuration

This listing covers one specific configuration of the Corvane Ardent 114 reflector, defined by its bundle, finish, accessory kit, and edition year. The GoTo mount finds objects from its database after a short alignment on two or three bright stars. Motorized tracking on the GoTo mount keeps objects in view, which helps when several people take turns at the eyepiece. Gloss white paint is easy to wipe clean, and the tube stays easy to spot in a dark yard.

The astrophotography kit adds a T-ring adapter for a camera body and a Bahtinov mask for precise focusing on a star. The 2025 edition keeps the same optical figures as the earlier years of the Ardent line. The optical figures in the specifications table apply to this configuration and to every other version of the Corvane Ardent 114 reflector.

Compatibility notes

• Accepts standard 1.25 in eyepieces, filters, and Barlow lenses.
• The Vixen-style dovetail bar fits small alt-az and equatorial mounts.
• Many DSLR cameras cannot reach focus at prime focus with this tube; a Barlow lens or a low-profile adapter helps.
