NASA's images of the sun show so much more detail & texture -- and they can see those not only because they have million dollar equipment and put it into space. These details also are visible to mere mortals -- once you focus onto very narrow bands of light with appropriate filters & technique.

Of all the astronomical phenomena, a TOTAL SOLAR ECLIPSE surely has to be the scariest of all to ancient people. What horrible powers must be at work when they can take away our sunlight. Of course today's explanation of standing in the moon's shadow is far less threatening (and not as imaginative as a dragon swalling the sun), solar eclipses still remain especially fascinating.

A standardized image format is something most users take for granted -- JPG, GIF, PNG and even TIFF are household names when it comes to (web)-images & editing. If you use a dSLR, you have gotten used to adding a tool or two, to process the Nikon or Canon RAW formats. With the astronomy cameras, the formats & necessary conversions become a real mess -- especially if you use a one-shot color "OSC" camera.

For this article, I use the eclipse on April 15th 2014 as an example and as a location I have picked San Francisco. The path of the moon & the timing is dependent on your own location and you will have to make adjustments for that. Here are some examples and a bit of background of the various attempts : www.ipernity.com/doc/stargazer95050/album/389379

[UPDATE 2013/12/20] Predicting the position of the Sun & Moon isn't all that difficult with a bevy of apps & websites to help you. Predicting satellite positions, incl ISS, is more specialized. Several tools of the SOFTWARE TOOLCHEST come in handy and I will have to add some new ones for this task. Once you know WHEN & WHERE it will happen, the next task is to figure out HOW. Especially when you aim to shoot a transit in front of the Sun, extra precaution is needed.
