Quillon Vista 15 mm eyepiece, with hard case

Specifications

Description

The Vista 15 mm is a six-element eyepiece with a 60-degree apparent field, 20 mm of eye relief, and a 1.25 in barrel. It gives medium magnification, the range where most deep-sky objects look their best in a typical amateur telescope.

In a 1,200 mm Dobsonian, the Vista 15 mm gives 80x and a true field of about 0.74 degrees. That frames globular clusters such as M13 with plenty of dark sky around them, shows the shape of the Ring and Dumbbell nebulae, and resolves the brighter open clusters into individual stars. In a 2,032 mm Schmidt-Cassegrain, it gives 135x for planetary use.

The 60-degree field gives a comfortable view without the weight and cost of wider designs. Stars stay sharp to near the edge in telescopes of f/5 and slower, with slight softening at the edge in faster Newtonians. The lenses are fully multi-coated.

The long eye relief makes the Vista 15 mm comfortable for observers with glasses, and the twist-up eyecup adjusts the eye position for observers without them. The barrel takes standard 1.25 in filters, so a nebula filter screws on directly.

A medium-power eyepiece often stays in the focuser for most of a session, because it balances image scale and field. The Vista 15 mm is a good choice for that role, especially when paired with a low-power eyepiece for finding objects and a high-power one for planets.

The rubber grip ring makes the eyepiece easy to handle with gloves on cold nights.

About this configuration

The Quillon Vista 15 mm eyepiece is offered in several configurations, and the notes below describe what this particular one adds. 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. The winged eyeguard wraps around the side of your eye and blocks light from nearby houses and streetlights.

The black anodized barrel and body resist scratches and do not reflect light into the eyepiece. The 2025 edition keeps the same optical figures as the earlier years of the Vista line. The true field in your telescope is roughly the apparent field divided by the magnification you reach with this eyepiece.
