DIY Telescope Experiment
A telescope is an optical instrument that makes distant objects appear closer using lenses or mirrors. This DIY telescope experiment allows you to build your own working telescope and explore basic astronomy concepts.
The first telescope was invented in 1608 in the Netherlands by Hans Lippershey.
Why I made it
This DIY telescope experiment helps you build your own telescope using simple materials and understand how lenses magnify distant objects.
Learn optics, reflection, and refraction in a fun hands-on way.
you can build a simple version at home and understand how it works.

How to build a telescope using simple materials
Materials & Components
You can use recycled materials like cardboard and PVC pipes. Be creative! Convex Lens (D: 7.5cm, F: 35cm) Eyepiece Lens (D: 2.2cm, F: 35cm) (🔁 Alternate Lens Options Objective Lens: 45–50cm focal length, 52mm diameter Eyepiece: 4cm focal length, 25mm diameter) Cardboard PVC pipe Black chart paper 🛠 Required Tools Scissors Paper cutter Tape (You can buy the kit from https://sciencestore.pk/product/diy-astronomical-telescope-kit/)
How to Make It
-
1🔰 Step 1: Prepare Lens Holder Mark a circle on cardboard using the lens as a guide. Marking circle for lens holder Cut the circle carefully. Cutting lens holder Now draw another circle using a PVC pipe in the center. Marking center for pipe Cut to form a doughnut shape. Make two such pieces.
-
2⚙️ Step 2: Prepare Telescope Body Take a black chart sheet (25cm × 60cm).
-
3🔭 Step 3: Roll the Telescope Tube Place the lens and roll the chart sheet around it. Basic telescope tube ready
-
4🔩 Step 4: Insert Lens Holders Insert the cardboard rings inside the tube at some distance. insert rings inside tube
-
5✂️ Step 5: Prepare PVC Pipe Cut PVC pipe into 3cm and 17cm pieces.
-
6👁 Step 6: Fix Eyepiece Attach eyepiece between the two PVC pipes using tape.
-
7🚀 Step 7: Final Assembly Insert the PVC pipe into the tube. Your telescope is ready!
