Quillon Vista 8 mm eyepiece

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

The Quillon Vista 8 mm eyepiece is offered in several configurations, and the notes below describe what this particular one adds. This configuration comes without a case, which suits observers who keep their eyepieces in a shared foam box. No case is included, so the eyepiece ships in a simple box with its two dust caps fitted. A winged eyeguard helps you hold your eye at the right position, which makes the edge of the field easier to see.

The black body with a color ring lets you tell focal lengths apart quickly under a red flashlight. This is the 2025 edition, which added a safety groove to the barrel and a firmer eyecup detent. The true field in your telescope is roughly the apparent field divided by the magnification you reach with this eyepiece.
