Aurel Veil 70 achromatic refractor, tube with alt-az mount

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

Every configuration of the Aurel Veil 70 achromatic refractor shares the same optics; the choices below change how the telescope is mounted, finished, and equipped. The included alt-az mount moves up and down and side to side, so you point the telescope by hand without polar alignment. Manual alt-az motion suits visual observing, though you need to nudge the tube now and then to follow objects as the sky turns. Carbon fiber saves some weight compared with a metal tube, which eases the load on the mount and on your arms.

The planetary kit adds a short focal length eyepiece and a set of color filters for the Moon and the bright planets. 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.
