QUARK Prominence Filter

Take you solar viewing to the next level with Daystar’s Quark Prominence filter. This all-in-one design combines components of a telecentric barlow, snouts and adapters, into one compact, research-grade hydrogen alpha filter. Just insert in the Quark, add an eyepiece, plug it in, and view both prominences and surface details!

The fully optimized design eliminates the need for any adapters with its combined-in-one lightweight, eyepiece-sized assembly. There is even reduced power consumption, so you can study or enjoy solar activity all day. (small, official Daystar Filters a palm-sized battery pack sold separately)
