Coronado 40 mm PST Calcium K Solar Scope (CAS #4)

CaK Scope Image

This telescope can piggy-back on a scope with a ¼-20 adapter or be used on a heavy duty camera tripod. This scope views the sun at the short wavelength violet/blue end of the visible spectrum. Older observers may have difficulty seeing significant detail because the eye becomes less sensitive to this wavelength with age. The scope can be used with a webcam to image the sun.  Loaned/Stored by: Ed P.   Available for check-out.
