constant, and the more readily detectable because chromospheric plage areas
traditionally are used to monitor this influence. In this context "active network" consists of
plage-like brightening extending away from active regions, as their magnetism appears
to diffuse into the quiet Sun, but constrained to follow the network boundaries.

Solar Flares: A solar flare is a violent explosion in the Sun's atmosphere. Solar flares
take place in the solar corona and chromospheres, heating plasma to tens of millions of
Kelvin and accelerating electron, protons, and heavier ions to near the speed of light.
They produce electromagnetic radiation across the electromagnetic spectrum at all
wavelengths from long-wave radio to the shortest wavelength gamma rays. Most flares
occur in active regions around sunspots, where intense magnetic fields emerge from the
Sun's surface into the corona. Flares are powered by the sudden (timescales of minutes
to tens of minutes) release of magnetic energy stored in the corona.
•
Chromosphere: The chromosphere is a thin layer of the Sun's atmosphere just above the
photosphere, roughly 10,000 kilometers deep (approximating to, if a little less than, the
diameter of the Earth). The chromosphere is more visually transparent than the
photosphere. The name comes from the fact that it has a reddish color, as the visual
spectrum of the chromosphere is dominated by the deep red H-alpha spectral line of
hydrogen.
Overview of the LS80T Hydrogen-alpha
The LS80THa is a complete Solar Telescope. The refractor-based system has a precision aligned
singlet chromatical lens with an 80mm aperture. The front singlet lens reduce half the stray light
of an achromat, it fully eliminates the possibility for on axis coma, astigmatism, de-centering
aberrations and provides with the matched collimation lens set a full spherical corrected flat-field
Solar-Telescope. The focal length is 560mm providing a ~5 mm image thru the 12mm blocking
filter. Fine adjustment is achieved with a Crayford Syle focuser with 10:1 reduction standard. An
internal etalon with tune adjustment allows for a <0.75 Angstrom bandpass.

Metal transport case with die cut foam insert and keys if the case has a lock.
•
Warranty card. Please fill out and return to activate your warranty.
•
Instruction manual.
What accessories are recommended?
•
Eyepieces. Simple eyepieces with narrow field of view are recommended. (25mm thru
8mm)

Sun block, a Lunt Solar hat, and a nice comfortable light colored chair.
Note:
•
The Telescope is shipped with the dovetail and Sol Searcher removed for safety during
shipping. We recommend that you use an exacto type knife to modify the foam insert as
required after you have setup the Solar Scope and you are happy with the placement of
the rings and the Sol Searcher.
