This eyepiece is designed with a 25 mm focal length and provides a 62-degree field of view, suitable for a wide range of observational needs. It features four lenses divided into two groups, each coated with multiple layers to enhance image quality by reducing reflection and increasing light transmission. 

Presenting a robust 5V, 22.4 Amp-hour battery pack equipped with the necessary cords for charging and powering the DayStar Quark Eyepiece Solar Filter. With the Quark requiring 1.5 amps at 5 Volts, this battery pack ensures extended operation for over a day.

Energy Rejection Filters are designed to reduce the heat load on your filter assembly by either absorbing or reflecting UV and/or IR light while transmitting light within the desired visual spectrum. These filters typically come in Red or Yellow glass variants, or as dielectric IR and UV filters, ensuring that light in the desired visual spectrum is passed through.

Connection (to the telescope): 1.25"

Introducing the Daystar Quark Gemini, a revolutionary tool that combines both Prominence and Chromosphere bandpass filters, allowing instant switching between the two views. With this innovative device, observers can seamlessly transition between broad-stroked prominences and high-contrast narrow bandpass views without the need for equipment swapping or refocusing.

Magnesium is a notably magnetized element present on the sun, known for its high temperatures during energetic activity. Spectroscopically, the Zeeman effect manifests as a "splitting" of the line, where dark absorption occurs slightly above and below the typical wavelength of non-magnetized activity, notably at 5172Å.

Observing and imaging the Sun in Sodium-D2 at 589 nm unveils intricate details within sunspots and the photosphere, surpassing those visible in white light.

Quality Achromat Doublet: This 60mm refractor boasts a high-quality doublet lens, delivering superior contrast and resolution for both visual observation and imaging.

The Daystar Instruments QUARK is an innovative, all-in-one Hydrogen Alpha filter system designed to simplify solar observation. Combining a telecentric barlow, adapters, snouts, and a hydrogen alpha filter into a single compact assembly, the QUARK allows users to convert their refractor telescopes into narrowband solar telescopes with ease. It is available in two models: Prominence for observing detailed solar prominences and Chromosphere for capturing surface details.

The Daystar Instruments QUARK represents a breakthrough in solar observation technology, offering the first Hydrogen Alpha "Eyepiece" filter. This innovative All-In-One design integrates high-quality components including a telecentric barlow, adapters, snouts, and a hydrogen alpha filter into a single, streamlined assembly. Through efficient design and optimization, astronomers can now access DayStar's renowned optical quality at a more affordable price point.

DayStar's Imaging Focal Reducer is designed to increase the field of view in your astrophotography images. This versatile accessory connects from a 2" eyepiece holder to a T-mount camera, with an included T extension tube for additional reduction options.
