The DayStar Filters Solar System filter wheel allows you to view the sun through up to four different filters with just the touch of a button. Switch from hydrogen alpha to sodium to helium to calcium and back again, effortlessly and accurately, using just one telescope. Each filter still has full ±1Å wing shift tuning capability, and the renowned Quantum precision control. Any of the DayStar wavelengths, bandpasses, or quality combinations can be used.
The Solar System filter wheel is great for outreach and education, as the behaviors of different elements and features on the sun can be quickly compared. The savings of not having to purchase a second or third solar telescope, and the quicker setup and takedown times, add up to big advantage.
