In the past few years, DayStar Quark H-Alpha solar filters have revolutionized solar observing. These innovative "solar eyepieces" include built-in etalon filters and temperature control to offer stunning views of the active surface and limb of the Sun in colorful H-Alpha. These compact devices simply slide into the focuser of many small "non-solar" astronomical telescopes, so you don't need to buy a separate solar scope.

DayStar originally released two models of the Quark, the Chromosphere and the Prominence. Now, they've combined both these models into a single new solar eyepiece: the DayStar Quark Gemini.

The Quark Gemini contains two separate and switchable Fabry-Perot etalon elements. Push the slider arm one way to observe dramatic solar prominencesat the sun's limb. Push the slider the other way to get the best views of chromospheric detail. No equipment swapping, no refocusing.

Production models of the Quark Gemini start shipping mid-June, and we're now taking pre-orders for this impressive 2-in-1 solar H-Alpha eyepiece.
