Astrophotography is all about capturing photons
In this article we explore the basics of trying to capture light from far off in the universe on a camera on the Earth’s surface.

The stars around Sirius make up the constellation of Canis Major which has some really nice open clusters to view through binoculars or a telescope.
This is the follow on video from Parts 1 and 2 and looks at the bit of sky between the Southern region and Orion, specifically between the False Cross and Sirius. You’ll also learn how to find M41 and M79.
The night sky is full of stars and some of the very brightest we see have some very interesting characteristics. Next time you’re looking at Sirius or Canopus you’ll be able to appreciate just how big they are compared to our very own star – the Sun.
This short video shows how to find the beautiful double star called 145 Canis Majoris, or sometimes known as the Winter Albireo.
The Stardate in the South Island over the weekend was a fantastic opportunity to learn about some objects that we haven’t seen before.
This video shows how to find the open cluster, M41, in Canis Major. Visible to both Northern and Southern Hemispheres.
(And we can do something about it.)
Life needs CHNOPS, the six essential elements Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulphur. Curiosity found them on ancient Mars, but a new study shows Earth was born without them. Only a lucky impact with Theia made our world habitable. In contrast, Venus never stood a chance. Meet the three planetary siblings and discover why only Earth became a cradle for life.
Mars’s mantle contains ancient fragments up to 4km wide from its formation—preserved like geological fossils from the planet’s violent early history.
Cosmic rays are hitting the atmosphere constantly. One of the products of the collisions is muons, and we can detect muons on the surface of the Earth to learn about the cosmic rays.
