Includes 90-240VAC wall adapter with international plug adapters.Brass compression ring to protect eyepiece.Standard 1.25-inch eyepiece drawtube output with optional 2-inch and SCT accessories available.Designed for use with f/15-f/30 SCT, Maksutov and Refractor owners.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. Specifically SCT owners must use a front mounted off-axis ERF to reduce their aperture. This specialized filter reduces heat built up in the optical tube keeping your eyes and telescope safe. The ERF is sold separately and is neccessary for safe viewing through a SCT or Mak-Cass telescope. See sunspots and surface swirls in gorgeous natural color and intense detail. The Chromosphere model is designed specifically to enhance surface detail. 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. Simply insert the Quark into your diagonal, pair with a ERF (energy rejection filter), add an eyepiece and view.
An innovative all in one design combines the needed adapters, snouts and DayStar H-alpha filter into a simple and compact assembly. Push the slider arm side to side like in an eye exam to see the broad stroked prominences of wider bandpass, then. Now, observers can enjoy the best of both options in one easy to use tool with no equipment swapping or refocusing of any kind.
