The Lunt Solar Systems Calcium-K Module Kit with 34mm Blocking Filter was designed especially for use with the LS152THa H-alpha dedicated solar telescope. It comes with a completely new Crayford-style focuser, and installs by simply unscrewing the three thumbscrews that hold the H-alpha unit and the focuser to the back of the LS152 OTA, and mounting the new focuser and CaK module - no tools required. The straight-tube viewing 34mm blocking eyepiece filter completes the solar filtering system and accepts any user-supplied 1.25" eyepieces and accessories.
This kit enables easy exchanging with the H-alpha system on the telescope, giving you the flexibility of imaging in CaK or H-alpha wavelengths. With the new focuser installed, just remove the CaK module, insert a standard diagonal, and the scope can be used as a normal astronomical night-sky telescope. The new Crayford-style focuser allows for ultra-precision focusing with zero backlash for tack-sharp images.
