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 :)

November 21st, 2011

I’m an hobby astronomer since i was young, I was always fascinated by the science and the nature around me, I also love photography and so  I started as soon as possible to take images with my first telescope, a 114 newton. In the past years i changed few times my main instrument passing by a Celestron 8 and a Celestron 11 and now I’m using a APO refractor, a 115 TMB Officina Stellare with Moonlite focuser on an Eq6 Pro. With the coming of digital imaging I can finaly follow all the process from the capture to the print and has improved alot what it can be reached.

I recently bought a Lunt h-alpha filter, the LS50FHa with blocking filter B1200 and I love it, I find the sun amazing and exploring his recent huge activity is a wonderfull sight. In this two months I improved my solar imaging and here are few examples of what you could see through your eyepieces.  If you want to follow my new captures you can visit my website [http://astropics.altervista.org/]

The animation represent the evolution of a portion of sun surface during 2 hour of observation. In the main window you can see the group NOAA 1302 while in the side zoom the active regione NOAA 1301    almost on the other side with few plasma eruptions.
Each frame has the same postprocessing work of a single image (registax stack/wavelet, photoshop curves/levels/color).
