Aurel Veil 70 achromatic refractor, tube only

Specifications

Description

The Veil 70 is a 70 mm achromatic doublet refractor with a focal length of 420 mm, which gives it a focal ratio of f/6. At that ratio the field at low power is wide enough for rich-field star clouds in the Milky Way, and the tube still takes moderate magnification on the Moon, Jupiter, and Saturn. You will see a faint violet fringe around very bright objects, because a two-element achromat brings only two wavelengths to a common focus.

The objective is fully multi-coated and sits in a tube with internal baffles, which keeps the background dark when a bright planet is near the edge of the field. The 1.25 in rack-and-pinion focuser uses a single-speed knob with a short travel range, so it holds a standard eyepiece without tilting. A 6x30 finder scope with a right-angle correct-image bracket mounts on the tube with two thumbscrews, and it helps you locate targets before you move to the eyepiece.

At 1.6 kg for the tube, the Veil 70 rides on a light alt-az mount or a small equatorial mount, and it fits in a soft case for travel. A small refractor reaches outdoor temperature sooner than a reflector of similar aperture, so you can start observing soon after you carry it out. Allow a few minutes for the optics to settle before you judge fine detail.

Typical targets include double stars such as Albireo and Epsilon Lyrae, the phases of Venus, the Moon's craters near the terminator, and open clusters such as the Pleiades and the Double Cluster in Perseus. At this aperture, the Orion Nebula shows its bright core and the surrounding haze, and many star clouds in Sagittarius and Cygnus fill the wide field of a low-power eyepiece.

About this configuration

The Aurel Veil 70 achromatic refractor is offered in several configurations, and the notes below describe what this particular combination adds or changes. 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. Gloss white paint is easy to wipe clean, and the tube stays easy to spot in a dark yard.

Color filters from the planetary kit can bring out surface markings on Mars and the cloud belts of Jupiter. The 2023 edition uses the same optical design as later years, with small differences in fittings and labels. The optical figures in the specifications table apply to this configuration and to every other version of the Aurel Veil 70 achromatic refractor.
