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.

Prominences:
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.

Filaments:
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.

Spicules
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 :)

The LS100 and the SBIG STL-11000
August 13th, 2010
No Comments »

Last month imager Brain Johnson tested out his brand new B3400 blocking filter on his LS100THa and boy did he use that blocker to its full potential!  The B3400 is currently the largest blocking filter in the Lunt family, this massive blocker is designed inside a 2″ straight through barrel allowing the largest of CCD cameras to be used!  For the shot below Brian used the famous SBIG STL-11000 CCD camera that sports an awesome full frame CCD sensor.  The field of view (FOV) is huge, its large chip allows Brian to image the entire solar disk in one shot!

Brian’s image shows an extremely detailed solar disk with two large active regions, a sun spot, and countless filaments!

Thanks for sending in your image Brian!
