Make your own tele­scope

All About Space - - Diy Space Projects -

The sim­plest op­tion. This DIY tele­scope can be is quicker and eas­ier to make than the other projects. With a sim­ple se­lec­tion of ma­te­ri­als and tools you can cre­ate your own slid­ing tele­scope, prob­a­bly best suited

as an ed­u­ca­tional tool.

Although it can’t pro­vide a de­cent enough fo­cus to delve into the true sights of the night sky, it is an ex­cel­lent ed­u­ca­tional ex­pe­ri­ence for a youngster or be­gin­ner. The gen­eral work­ings of a re­flec­tor tele­scope

can be learnt, such as light fo­cus­ing, and if this pro­ject takes your fancy then you could try a more ad­vanced ver­sion.

Ma­te­ri­als check­list

The list of ma­te­ri­als and tools needed for this pro­ject is sim­ple, con­tain­ing mostly house­hold items. In or­der to make your own tele­scope you must have a large piece of black Bris­tol board, a glue gun, a sta­pler, black elec­tri­cal tape, a pair of scis­sors, a card­board tube and two mag­ni­fy­ing glasses – ideally one should be big­ger than the other.

Fix the lenses

The first, larger lens should be glued to the top of the card­board tube and se­cured with elec­tri­cal tape. At the other end of the tele­scope the se­cond lens should be fixed to the end of the slider tube, sim­i­lar to the first lens. The slid­ing fo­cus lens will con­cen­trate the light from more dis­tant ob­jects to suit your eyes.

As­sem­bling the tubes

Cut three black Bris­tol board sheets – two to fit around the card­board tube and one twice the length. Glue the smaller sheets around and within the card­board tube, and place the longer sheet in the tube, sta­pled at its ends, glued and wrapped in elec­tri­cal tape to se­cure it, while still al­low­ing it to slide in and out prop­erly.

Fin­ish­ing touches

Once the tele­scope is com­plete some fi­nal dec­o­ra­tive touches can be added. Tak­ing some crayons, or coloured chalk, you can draw some con­stel­la­tions over your tele­scope, but this is de­pen­dant on your per­sonal pref­er­ence. Now everything is in or­der to give your new tele­scope a test run and see what sights are at your dis­posal.
