DayStar Filters Camera Quark H-Alpha Solar Filter for Canon EF (Prominence)
Key Features
  • 656nm H-Alpha Filter with 12mm Blocking
  • Tuned for Prominence Viewing
  • Use Canon EF Lenses for Solar Imaging
  • ±0.5Å Wing Shift Tuning
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 EF camera 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.

Warning: Viewing the Sun without proper protection can cause permanent eye damage, blindness, and equipment damage. Always use an approved ISO 12312-2 certified solar filter when observing the Sun through optics or cameras. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.
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 EF camera 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 EF 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.

Filter Properties
  • Hydrogen-alpha bandpass
  • Integrated 12mm blocking filter
  • 20mm clear etalon aperture
  • Tuned to 0.8-0.6Å for viewing prominences
  • Tuning knob allows for ±0.5Å wing shift for Doppler-shift compensation
  • Markers at every 0.1Å for reference and repeatability
  • LED indicators for power, warming, ready, and fault
Optics
  • Integrated 4.2x Barlow lens
  • Lens and optical coatings designed specifically for 656nm H-alpha wavelength
  • Two-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increases

  • Front and rear bayonet mounts for Canon EF cameras and lenses
  • Full disk viewing possible on lenses up to ~450mm focal length lenses
  • Includes focal extender spacer ring to ensure compatibility with a wide variety of lenses
  • No electric pass through on filter so lens features like auto-focus and electronic aperture control will not work
  • Focus and clearances not guaranteed for 100% of lenses
  • Use of red, orange or yellow colored glass lens front filters recommended
  • 1.25" eyepiece adapter to use conventional astronomical eyepieces and convert lens into solar telescope

question

DayStar Filters Camera Quark H-alpha Solar Filter for Canon (Prominence): Does this provide product adequate filtration of the sun for the upcoming eclipse, or does it need to be used in consort with additional filters on camera/scope for viewing?
Asked by: Rachel H.
The DayStar Filters Camera Quark H-alpha Solar Filter for Canon (Prominence) goes between your lens and camera. You still need a ERF (energy reflecting filter) on the front of your lens. This will prevent damage to the lens. For help choosing a ERF (energy reflecting filter) for your lens email us at [email protected].

question

Looking at the video, there does not appear to be any filter in front on the front element on the telephoto lense. Wouldn't you have to have a solar filter in front to keep from damaging the internal components of the telephoto lens? Should you use a Mylar solar sheet like I normally use for telephoto sun pictures.
Asked by: Ron
You are right,it is called ERF(energy reflecting filter). I have ordered one with my Ha filter Aug 3 but has not arrived. So haven't been able to used the Ha filter.
