The Sun is our Star!
.......and as you would expect, our Star is hot, bright, dynamic, and sometimes quite violent.
At 93 million miles away, we are ideally placed at a point where the Sun provides just enough warmth and energy essential to our living planet, Earth.
At only 93 million miles, the Sun is close enough for us to view it's surface thru a relatively inexpensive scope from the comfort and relative safety (Sunscreen please) of our backyards on a clear and warm day.
What! Astronomy during the day? Lunt Solar wants to show you how.
These look like eruptions from the edge of the Solar disk. Prominences can be small spikey looking details, or large cloud-like detail with fine feather-like features.
They are, in fact, ionized Hydrogen-alpha emissions being projected from the linb.
Prominences are anchored to the Sun's surface in the Mesosphere, and extend outward into the Sun's Troposhere.
They typically measure many earth diameters.
These are strin-like features on the surface of the Sun.
At high resultion they take on a 3D effect due to the coller aspect of the suspended filament contrasted against the bright, hotter Sun.
They are actually prominences being viewed against the surface.
A Spicule is a dynamic jet of gas about 500km long.
They move outward at about 20km/second thru the Chromosphere.
Father Angelo Secchi of the Vatican Observatory discovered them in 1877.
The Chromosphere is entirely composed of Spicules. These features can be seen as "fur"around the edge of the disk.
There's definately stuff to look at :)
These CaK OTA’s are no longer available. Lunt are now offering 3 ED options that can be used for CaK, White Light, and Night Use.. Please contact Sales at Lunt Solar for more information..
Descriptions and pictures of the New products will be psoted soon…
Calcium K (Ca-K) Telescopes and Filters are used to study the wavelength of 393.4nm. This emission line is one of 2 that are produced by Calcium just at the edge of the visible spectrum in 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 and the Hydrogen-alpha line provides important insights into the structure, strength, and depth of these active regions.
The Calcium K line is centered at 393.4nm. 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.
The LS60/Ca-K is a complete Solar Telescope for the Calcium-K line. The refractor based system has a precision aligned Ca-K optimized doublet achromat with a 60mm aperture. The focal length is 500mm providing a ~4.5mm image thru the B600 blocking filter. Fine focus adjustment is achieved with a Crayford focuser with 10:1 reduction.
Internal narrowband filters allow for a <2.4 Angstrom bandpass. Primarily an imaging system due to the difficulty of many to visually see everything that Ca-K has to offer. Lunt Solar will be introducing an imaging package for use with this system.

• optical tube with 2″ Crayford Focuser and tube ring
