About the DayStar Combo Quark H-Alpha Eyepiece - Chromosphere Model...
The Combo Quark offers a choice for the SCT and long focal length user. Designed for SCT, Maksutov Cassegrain and refractor owners with focal ratios between f/15 and f/30. An innovative all in one design combines the needed adapters, snouts and DayStar H-alpha filter into a simple and compact assembly. Simply insert the Quark into your diagonal, pair with a ERF (energy rejection filter), add an eyepiece and view. The compact design of the Quark allows you to view the sun in full hydrogen alpha glory without the weight and expensive components associated with more traditional systems.
The Chromosphere model is designed specifically to enhance surface detail. See sunspots and surface swirls in gorgeous natural color and intense detail.
The ERF is sold separately and is neccessary for safe viewing through a SCT or Mak-Cass telescope. This specialized filter reduces heat built up in the optical tube keeping your eyes and telescope safe. Specifically SCT owners must use a front mounted off-axis ERF to reduce their aperture. Maksutov owners operating at f/15 natively do not need to reduce the aperture of their telescope with an off-axis filter but do still need to employ a front mount ERF to keep heat from accumulating.
