SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

Building on the success of the standard versions of their Quark, Daystar Filters designed this version of the Camera Quark H-alpha Solar Filter to fit Canon SLR and DLSR bodies and lenses to allow imaging or viewing prominences. To fit your camera system, the each end is equipped with a corresponding bayonet mount for easy attachment, and full disk viewing possible on lenses up to ~450mm focal length. A rear 1.25" eyepiece adapter is included to allow the use of traditional astronomical eyepieces. This adapter essentially converts your lens into a solar telescope. Daystar recommends the use of red, orange or yellow colored glass lens front filters for apertures over 80mm.

The filter is tuned to the 0.8-0.6Å bandwidth of the 656nm hydrogen-alpha wavelength with the ability to tune it ±0.5Å from the center line for compensate for Doppler shift or to focus on specific regions or features, with indicators every 0.1Å. Prominences, a detail of the chromosphere projected against the blackness of space behind the sun, are seen with improved contrast due to the filter's narrower bandpass versus a wider bandpass filter tuned for conventional chromosphere surface viewing. The filter is powered via a micro-USB port, and Daystar includes a power cord and an AC adapter to meet the high-power requirements of 5 VDC 1.5A. To enable its use at home and abroad, a set of international outlet plugs is provided with adapters for the US, UK, EU, and Australia.

The Camera Quark comes with a combination lens foot with 1/4-20 tripod holes to mount it on conventional photo/video/field tripods, and a Vixen-style dovetail plate for telescope mounts. While a focal extender spacer ring is included to ensure compatibility with a wide variety of lenses, focus and clearances are not guaranteed with all Canon lenses. Because there is no electric pass-through on the filter, when installed between the camera body and lens, some lens features such as auto-focus and electronic aperture control will not work.
