How To Guides

Say goodbye to wet knees and aching joints with this DIY astronomy project – an observing chair that folds flat for easy storage.
A simple project to help you to locate targets with a Dobsonian

Point accurately to anywhere in the night sky with this simple project to help you to locate targets with a Dobsonian telescope.

Capture the celestial sphere and reveal the movement of stars

An all-sky camera is an ideal tool for capturing the majesty of the celestial sphere turning silently overhead.

With it you can make timelapse videos that reveal the movement of the stars as well as record bright meteors and satellites.

 

How to build a tabletop tracking mount

This project is a simple tabletop mount that can track the apparent movement of the stars, which allows you to increase exposure times and capture more light with your camera.

How to keep warm when observing

Winter nights provide a wealth of observing treasures, but they come at a price: sub-zero temperatures. Here’s how to beat the cold to enjoy the sky.

How to observe variable stars

In astronomy, not all stars shine with constant brightness. Here we show you how to chart the changes in variable stars.

How to thermally optimise your telescope

Tube currents in your telescope can affect the ability of the optics to bring light to a sharp focus. We show you how to combat these irritating effects.

How to build a Dobsonian mount

The Dobsonian telescope is simplicity itself: a Newtonian reflector mounted on a basic altaz mount. Many thousands of astronomers have constructed their own Dobsonians, but the satisfaction of building your own mount is immense.
