Homemade Astronomy.

This evening I have a great desire to take a great photo of the ISS (International Space Station).
Time ago I took a picture and the result was very good considering I took that photo "on the fly" with the following parameters:

• t = 44 secs
• f/6.3
• ISO = 100
• 27 mm

The final image was this (consider I took that picture in RAW and elaborated it in PNG format with reduced sizes):

(Click on the image to see it better)

Soon I'll have the opportunity to find the precise sizes to take a better photo!
I want to eliminate a lot of light of the horizon (there are some light poles) and the duration of the transit is ca. 1 min and 43 secs (longer than the previous).
So I decided to take this new picture with these new values:

• t = 2 min
• f/13
• ISO = 100
• Focale between 18 and 55 mm

It wasn't a good idea... -.-' ISS was too low on the horizon and there was a lot of mist. It was better when I didn't prepare anything and I took a photo on the fly like this:

Particular of a photo taken with these parameter:

• t = 50 secs
• f/8
• ISO = 100
• 21 mm

Ok...that's all folks!
...follow me to the next adventure!
