Lunt Solar CaK Module For The LS130T Modular Telescope
This product provides you with a Lunt Solar Calcium-K line (CA-K) filter module, 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 at the Calcium K spectral line wavelength, instead of at the Ha line.
Calcium K (Ca-K) telescopes and filters are used to study the wavelength of 393.4 nm. This emission line is one of two that are produced by Calcium just at the edge of the visible spectrum. This information comes from a layer that is slightly lower and cooler than the layer viewed in Hydrogen-alpha. The emission line displays areas of super granulation cells that are brightest and strongest in areas of high magnetic fields, such as sunspot activity and active regions. Having the ability to study the Calcium K as well as the Hydrogen-alpha line provides important insights into the structure, strength, and depth of these active regions of our Sun.
This is easily accomplished in seconds by switching from your H-Alpha filter to your Calcium K module. This device is not recommended for visual observing use, due to the common inability of persons to see much detail at this wavelength band which is partly invisible!
The Calcium K modules line is centered at 393.4 nm. This wavelength is considered to be slightly outside the visible spectrum on the UV side. While most people can visually see the violet color of the wavelength, many cannot resolve the contrast due to yellowing of the cornea. People who have had cataract surgery are often able to see considerable detail. But, it is for these reasons that the Ca-K line is typically studied via the use of cameras, which are able to provide stunning details.
Internal narrowband filters allow for a <2.4 Angstrom bandpass. This is primarily an imaging system due to the difficulty of many to visually see everything that CaK imaging has to offer.
