Daystar Instruments QUARK is the first Hydrogen Alpha "Eyepiece"

This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and hydrogen alpha filter into one simple assembly. Through design efficiency and optimization, now users can enjoy the known high quality optics of DayStar at an affordable price.

QUARK is available in a choice of "prominence" or "chromosphere"

Best performance for use on refractors of F/4 to F/9. You don't need to worry about configurations. Just insert in your diagonal, add an eyepiece and view. Full disk viewing possible on refractors up to 450mm focal length refractors.

To prevent damage, we recommend using an Energy Rejection Filter on telescopes of 80mm aperture or more, or when tracking the Sun for long periods. This can be a UV/IR cut filter mounted before the diagonal, or a full aperture red or yellow glass ERF mounted in front of the telescope.

The QUARK contains a custom Daystar Instruments 4.2X telecentric barlow lens fully optimized in coatings and optical design specifically for the Hydrogen Alpha wavelength. This highly specialized telecentric lens offers superior field flatness.

Exact filter bandpass will vary based on final telescope application, so QUARK assemblies are qualified to show either prominence or surface (chromosphere). No specific FWHM bandpass is designated. Now observers can buy a filter based on their desired observing goals instead of their budget: Choose prominences and surface (Chromosphere) detail.

The fully optimized design eliminates the need for any adapters. It's all combined in one lightweight eyepiece sized device. The new, compact design configuration eliminates unnecessary components, weight and associated costs. Baffles have been added to increase contrast and AR coatings are optimized for the 656nm wavelength.
