Thank you all.

Thanks pareticolare friend Max57.

I answer to Simon
The focal length of 3070 mm is used, obtained from 714 mm telescope original multiplied by the magnification of 4.3x gernerato from sunscreen Daystar Quark, which contains a Barlow lens telecentric by 4.3x.
The picture is not a photograph, was achieved by mounting a CCD output of the telescope can take a movie AVI at 12 frames per second, the sum of which with a particular software (Avistack 2.0, free) has been processed a file TIFF from which I drew up the final photo.

Hellish, really. Congratulations

A curiosity: what is edging around purplish? And 'the effect of the union of the frames or other?

Infernal and otherworldly as he said those who preceded me are the adjectives suitable for this unique image. I also ask the origin of edging purplish between the sun and the dark background.

The thin dark line that you see in the picture is due to the selection of the solar surface, on which I applied the method of inversion for more details, then I had to do the reverse selection otherwise the background would become white, with prominences invisible.
You can still remove a tiny clone stamp, m but this takes a bit of time, so I did.
It 'the only way to make visible both prominences (the gray one is wide surely more than 150,000 km, then at least 12 times greater than the diameter of Terera!) That the solar surface.
The vision with a tool similar to mine in band H-Alpha (hydrogen burning on the Sun) is the eyepiece of an intense red color, both for the solar surface that the protrusions, while the background apparand white.
Now, considering that the CCD cameras of high sensitivity shooting in Black and White, I try to do a color that may please, according to personal taste.
