Yet it should never be forgotten that the simplest (and often, most stunning) astrophotography is possible by use of a camera (and its terrestrial lens) alone. For instance, merely pointing a static camera at the sky and exposing for a few minutes enables this humble device to reveal both the giddying motion of a spinning Earth and the colours of the stars — with the latter consequently revealing each star’s general spectral class (and therefore surface temperature); not bad for an imaging device that is not even connected to a telescope!

But in dim nocturnal light, it can be difficult to accurately aim the camera at a particular target in the sky. Red dot finders could facilitate this function, but their feet are not designed to hop aboard DSLR cameras — until now. The Geoptik hotshoe adapter is a convenient mediator between a camera and a red dot finder’s dovetail. Two locking screws ensure a firm grip and alignment.

Price: £45
