Product overview

The Quark Chromosphere turns a suitable refractor into an H-alpha system for observing the solar chromosphere. Its narrower tuning is optimised for high contrast in filaments and surface detail.

Suitable applications

• Experienced solar observers
• Owners of suitable refractors around f/4 to f/9
• Visual and photographic observation of chromospheric detail

Included equipment

• 1.25- and 2-inch connection
• Temperature-controlled filter
• USB power supply with mains adapter
• Designed for refractors around f/4 to f/9
• Integrated telecentric optics

Use with a refractor

With shorter focal lengths, the full solar disk may fit depending on the setup. Larger apertures and longer focal lengths are especially useful for detailed views.

Safety information

Solar observing requires appropriate protective measures. Follow the manufacturer's instructions in full and never use improvised filtering solutions.

Practical note

Use the filter only in accordance with the DayStar instructions. Depending on telescope aperture and configuration, additional energy-rejection or UV/IR protection may be required.
