Daystar Quark

If you plan on using binoculars or a telescope during the great solar eclipse of August 21, 2017, you’ll be one of lots of people who will purchase an approved filter. Most will buy visual solar filters , also known as “white-light” filters. Such an accessory reduces the Sun’s visible light to a safe and comfortable level and lets you see sunspots .

But if you want to see more than just sunspots , you’ll need to move into the realm of Hydrogen-alpha (Hα) observing. Daystar Filters, a company that has been making such products for decades, has introduced a new player—the Quark—into that arena. It combines an all-in-one unit and the ultimate in portability with a price point below all but the smallest Hα filters.
