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.
