CaK Module Package for LS152THa


General Features:

  • Calcium K module for the 152T with an internal 2.4 Angstrom blocking filter.  Now you can image in multiple wavelengths with your LS152THa!
  • This package also comes with a standard 2″ Crayford-style Focuser, which means you can use your LS152Tha as a regular nighttime telescope (with a regular diagonal inserted as opposed to the CaK diagonal), or observe the Sun in white light with a Lunt Herschel Wedge!

Product Description

You can easily exchange the H-alpha system on the Lunt LS152THa for this Ca-K Module whenever you like, giving you the flexibility of imaging in CaK or H-alpha wavelengths.

The CaK module was designed especially for the LS152THa H-alpha telescope.  It comes with a completely new focuser. Simply unscrew the three thumbscrews that hold the H-alpha unit and the focuser to the back of the LS152 OTA and install the new focuser & CaK module; it’s that easy.

With the new focuser installed, the LS152T can also be used as a normal astronomical night-sky telescope (just remove the CaK module and insert a standard diagonal), or you can observe the sun in white light with a Lunt 2″ Herschel Wedge (sold separately)!
