This new, all-in-one design marries high-quality components of a telecentric Barlow,  adapters, snouts and Daystar hydrogen alpha filter into one simple assembly. Through design efficiency and optimisation, users can now enjoy the known high-quality optics of DayStar at an affordable price. 

For use on refractors of F/4 to F/8 (QUARK Filters may be used at shorter and longer focal ratios than recommended. F-ratios of F/9 and higher will offer a dimmer visual view and may only be bright enough for photographic applications. F-ratios of less than F/4 will be brighter but also widen the effective FWHM bandpass performance of the QUARK filter.).  The user needn't worry about configurations. Just insert in your diagonal, add an eyepiece and view. 

The patent pending QUARK contains a custom Daystar Instruments 4.2X telecentric Barlow lens fully optimised in coatings and optical design specifically for the Hydrogen Alpha wavelength. This highly specialised telecentric lens offers superior field flatness.

The exact filter bandpass will vary based on the 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 or surface (Chromosphere) detail. Both are available for the same low price!

The fully optimised design eliminates the need for adapters. It is all combined in one lightweight eyepiece-sized device. The new, compact design configuration eliminates unnecessary components, weight and associated costs. We even reduced power consumption, so the QUARK can now operate all day off a small, palm-sized optional battery pack.

Baffles have been added to increase contrast, and AR coatings are optimised for the 656nm wavelength.

Important: Concentrated sunlight can create very high temperatures where it falls, so care must be taken to prevent melted components or fire.

For brief observing sessions with less than 80mm of aperture when not using a tracking mount, it can be OK to use no energy rejection at all. Be alert for any rise in temperature of your telescope, diagonal, or QUARK.

For telescopes under approximately 120mm of aperture, a screw in UV/IR cut filter can be employed in front of the telescope diagonal. The UV/IR cut filter reflects UV and IR light back out the front of the telescope, reducing temperatures inside. Do not use a UV/IR cut filter with oil spaced objective telescopes, or any telescope with an integrated rear field flattener or Petzval lens. The UV/IR cut filter must be the first optical element to receive concentrated light.

For best performance, a red or yellow glass front mount Energy Rejection Filter should be used. This prevents almost all heat from entering the telescope, and is the safest option.
