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 and 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-inch Herschel Wedge (sold separately)!
