DayStar Quark Gemini H-Alpha Solar Filter – Product description

H-alpha system with switchable Chromosphere and Prominence tuning for suitable refractors.

Key product details

• Experienced solar observers
• Users who want chromosphere and prominence views with one system
• Suitable refractors within the recommended focal-ratio range
• Switchable Chromosphere and Prominence modes
• 1.25- and 2-inch connection
• Temperature-controlled filter with fine tuning

Product overview

The Quark Gemini combines two H-alpha tunings in one device. A sliding mechanism enables you to switch between higher contrast on the solar disk and a tuning optimised for prominences.

Suitable applications

• Experienced solar observers
• Users who want chromosphere and prominence views with one system
• Suitable refractors within the recommended focal-ratio range

Included equipment

• Switchable Chromosphere and Prominence modes
• 1.25- and 2-inch connection
• Temperature-controlled filter with fine tuning
• 12 mm blocking filter
• Integrated telecentric optics
• USB power

Flexible H-alpha use

The Gemini enables direct comparison of both tunings without changing the filter system. Larger refractor apertures may require additional protective filtering.

Safety information

Solar observing must only be carried out with a fully suitable and correctly configured filtering system. Follow all manufacturer requirements regarding aperture, UV/IR protection and energy rejection.

Practical note

Check DayStar's requirements for your exact refractor before use. With larger apertures, suitable UV/IR or energy-rejection protection is especially important.
