Quillon Vista 8 mm eyepiece, with hard case

Specifications

Description

The Vista 8 mm is a seven-element eyepiece with a 60-degree apparent field, 20 mm of eye relief, and a 1.25 in barrel. The Vista line keeps the same long eye relief across all focal lengths, so observers with glasses can use high magnification comfortably.

In a 1,200 mm Dobsonian, the Vista 8 mm gives 150x and a true field of about 0.4 degrees. In a 900 mm reflector it gives 113x, and in a 714 mm refractor about 89x. That range covers planetary detail, lunar features, close double stars, and the brighter planetary nebulae.

Long eye relief at a short focal length requires a more complex design. The Vista 8 mm uses a negative lens group at the bottom of the barrel to lengthen the eye relief, followed by a positive group that flattens the field. Stars stay sharp to near the edge in telescopes of f/5 and slower.

The twist-up eyecup has three positions, which sets your eye at the right distance with or without glasses. The lenses are fully multi-coated, and the barrel has a filter thread for 1.25 in filters.

Because the eye relief is generous, you may need to hold your eye back a little to see the whole field. Raising the eyecup to its top position helps you find the right place quickly in the dark.

The Vista 8 mm works well as the high-power eyepiece in a set with the Vista 15 mm and a low-power wide-field eyepiece. Together they cover most magnifications that typical telescopes and sky conditions support.

About this configuration

This listing covers one configuration of the Quillon Vista 8 mm eyepiece, defined by its case, eyecup, finish, and edition year. The hard foam-lined case protects the eyepiece from knocks during travel and stacks neatly with other cases. A hard case keeps the eyepiece safe in a busy accessory box at a star party or an outreach event. A fold-down eyecup is simple and has no moving parts that can loosen in cold weather.

Black anodizing is the standard finish of the Vista line and matches most focusers. This is the 2023 edition of the Vista line, the earliest version that is still listed in the catalog. The true field in your telescope is roughly the apparent field divided by the magnification you reach with this eyepiece.
