DayStar QUARK – turn your telescope into an H-alpha telescope
Wouldn't it be nice if you could simply view solar prominences with your existing telescope without having to buy a special solar telescope? The DayStar QUARK is the first H-alpha eyepiece that makes this possible!
Simply insert this special eyepiece into the focuser of your refractor. And just like magic, it becomes a fully-fledged H-alpha telescope.
One QUARK to see everything – that's all you need
QUARK is a world first because it is a compact all-in-one filter package. Simply insert QUARK into the diagonal mirrors of your refracting telescope like an eyepiece. And you can observe impressive spicules, prominences or filaments. The prominences at the edge of the Sun appear bright and extremely detailed.
The QUARK Combo Gemini is suitable for SC and maksutov telescopes, as well as refractors with an aperture ratio of f/15 to f/30.
Please note: An ERF (Energy Rejection Filter) objective lens filter is essential for use with SC or maksutov telescopes!
