Daystar Quark Gemini Hydrogen alpha Filter contains both Prominence and Chromosphere bandpass filters for instant slide-action switching between either view.

Now, observers can enjoy the best of both options in one easy to use tool with no equipment swapping or refocusing of any kind. Push the slider arm side to side like in an eye exam to see the broad stroked prominences of wider bandpass, then the high contrast of narrow bandpass. Imagers can do comparison images and outreach astronomers can demonstrate surface structure and prominences and the science involved in wing shift.

Note: GEMINI FILTERS ARE CURRENTLY MADE TO ORDER AND SHIPPING TIMES MAY VARY.
