Explanation:
Whats that rising over the hill?
A galaxy.
Never having seen a galaxy themselves, three friends of an industrious astrophotographer
experienced an exhilarating night sky firsthand that featured not only the
band of our Milky Way galaxy but also
Milky Way's neighbor -- the
Andromeda galaxy.
Capturing the scene required careful pre-shot planning including finding a good site,
waiting for good weather, balancing relative
angular sizes with a zoom lens, managing
ground lighting, and minimizing atmospheric light
absorption.
The calculated shot therefore placed the friends on a hill about 250 meters away
and about 50 meters up.
The featured single-exposure image was taken last July 26 at about 11:30 pm in
Guatape,
Colombia,
about two hours from
Medellin.
The surrounding stars visible are all nearby in our own galaxy, while the small galaxy
just above
M31
is Andromeda's satellite
M110.
