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 its surface through a fairly inexpensive specialized scope from the comfort and relative safety (sunscreen, please) of our backyards on a clear and sunny day.

What! Astronomy during the day? Lunt Solar wants to show you how.

Prominences:
These look like eruptions from the edge of the Solar disk. Prominences can appear as small spiky-looking details, or large cloud-like detail with fine feather-like features. They are, in fact, ionized Hydrogen-alpha emissions being projected from the limb.

Prominences are anchored to the Sun's surface in the Mesosphere, and extend outward into the Sun's Troposphere. They typically measure many earth diameters.

Filaments:
Filaments are string-like features on the surface of the Sun. At high resolution they take on a 3D effect due to the cooler aspect of the suspended filament contrasted against the bright, hotter Sun.

Filaments are actually prominences being viewed against the surface.

Spicules
A Spicule is a dynamic jet of gas about 500km long. They move outward at about 20km/second through 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 definitely stuff to look at :)

Lunt LS50THa Solar Telescope

Lunt Solar Systems is excited to announce our new 50mm Pressure Tuned dedicated Hydrogen-alpha telescope, the LS50THa!

The LS50T is a refractor-based system with a 50mm aperture and an internal-mounted etalon with Pressure Tuner adjustment.  This system allows for a  <0.75 Angstrom band pass.

Specifications: (single stacked)

  • Type: Single Interference Etalon
  • Tuning: Internal Pressure Tune (Doppler True Tuning)
  • Aperture: 50mm
  • Focal Length: 350mm
  • F Ratio: F7
  • Bandpass: <0.75 Angstroms @ 656nm
  • Focuser: Helical Focuser
  • Mounting: Integrated clamshell style with 1/4-20 tapped base
  • Color: Pearl White with Black and Red accents
  • Diagonal: B400 Blocking Filter (standard) or B600 Blocking Filter (upgrade)
  • Skill level: Beginner on up
  • Shipments to begin in June, 2014

Lunt Solar LS50THa Pressure-Tuned Pricing:

LS50THa/B400PT
* Standard system with B400 visual use blocking filter
Introductory Price:   $799.00

LS50THa/B600PT
* Standard system with B600 visual use blocking filter
Introductory Price:   $899.00

Especially designed LS50C Compact double stack filter is also offered for $895.00.

The LS50C allows you to lower the bandpass to <0.5 Angstroms, which gives you much more surface detail.  The filter threads directly onto the LS50THa.

ERF Pricing:

Product Number: LS40ERF
*40 mm aperture ERF
Price: $99.00

Product Number: LS50ERF
*50 mm aperture ERF
Price: $109.00
