Lunt Solar CaK Module w/Backing Plate and Focuser For LS130T

This product provides you with a Lunt Solar Calcium-K line (CA-K) filter module, as well as a Backing plate and 2" Crayford Focuser for your existing LS130T Modular Solar Telescope.

This item will attach to the rear of your LS130THa Modular Solar Telescope and allow you to perform imaging work at the Calcium K spectral line wavelength, instead of at the Ha line. Imaging is the primary task, because the Ca-K wavelength is nearly impossible to see visually, to a useful extent.

• Includes Ca-K filter module with Focuser and Backplate
• Weight: 3 pounds
• Dimensions: 7"x 6"x 5"
