welcome

Amateur astronomers have a proud tradition of making their own equipment. This do-it-yourself ethos was evident from the very beginning: the telescope that Galileo used to make his revolutionary observations of Jupiter’s largest moons was a product of his own hands. Closer to our own time, many innovations we see on commercial telescopes today appeared first on home-built instruments: the Dobsonian telescope, its simple design invented by US amateur astronomer John Dobson, and the Crayford focuser, first designed in the 1960s by UK amateur John Wall. The Big Book of DIY Astronomy Projects follows this heritage and on the following 114 pages you’ll find all the information and instructions you need to cost-effectively build, equip and upgrade your home viewing platform. We’ll show you how to do everything from making a…

a diy astronomer’s   workshop

To make the projects described in this special issue, you’ll need some tools and a suitable workspace, so here we’ll advise you about the equipment you need to get started. Choosing the right toolkit should not involve spending lots of money or sourcing extravagant machinery. You may have many of the items on our list already, but if not, everything can be bought from your local DIY store. The tools are also useful for jobs around the home, so you will find plenty of applications for them between projects. A fully equipped workshop would be a dream scenario, and professionals and DIY aficionados may wish to add to our basic list, but the aim here is to give some sensible suggestions to those of you who are just beginning. Tools We recommend purchasing good…

make a   binocular   dew shield

If you mount your astronomical binoculars, they spend a long time aimed at the sky, resulting in much more radiative cooling than you get with handheld use. With few exceptions, binoculars don’t have any form of dew shield and the consequence is that you can find your observing session cut short by the fading mushy images that are the sign of dew forming on your objective lenses. So here we show you how to make a simple dew shield to extend your observing sessions. Dew forms when an object cools to a temperature called the dew point. The actual temperature of this threshold depends upon the humidity of the air. As the air cools, it can’t hold so much moisture, so the relative humidity increases until it reaches 100 per cent,…
