When we talk about planets, constellations, galaxies is believed that it is often very distant objects, only the reach of scholars and indeed by some very skilled lover.
When it comes to photograph the reaction of most photographers is the same.
Instead, most of these bodies is under our nose, or rather would say over our nose, each day and the greater difficulty is usually only in identifying.
At the suggestion of a friend (thanks Antonio) so I tried to take not only the largest planet in our solar system, Jupiter, its satellites, but also more visible.
The equipment used was:
- Canon EOS 40D (preferred in this case, the 5D for its multiplication factor)
- EF 70-200mm f / 4 L USM (excellent quality but with a focus not particularly long)
- EX500 Benro Tripod with ball head
- Remotes
To focus, I used the live view in the 40D is equipped with screen magnification 10x which also helped me find just the right exposure that would make visible the Galilean moons.
I used a fairly open aperture, f/5.6, so as not to lengthen the time. This is because even if the apparent motion of stars is too slow to be seen with the naked eye, just a shutter speed a little longer to notice them a trail where there should be a point.
Sensitivity ISO 400 it seemed a good compromise for not having excessive noise.
With an exposure of 1 second that was the result:
details and color of the giant planet are invisible from exposure needed to make visible the moons.
To test I then made an attempt with the compact, a Canon Powershot A650 IS, the maximum focal length and using a tripod table.
is the result:
not measure up to that obtained with the camera, however, shows that certain results, completely unexpected, would be available to everyone.
