Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: Material Required

1-Bolt of big size (1 bolt)

2-Bolt of medium size (10 bolt)

3- Bolt of small size (4 bolt)

4-Nut (3 nuts for the big size bolt)

5- One pipe clamp

6- One biconvex lens(for objective)

7-One biconvex lens(for eyepiece)you may also use an eyepiece you have

8- Three PVC pipes, according to the size of objective lens and eyepiece

9-One PVC pipe cap.

## Step 2: Lens Calculation

I am using biconvex lens with an aperture of 90 mm and focal length of 500 mm

it can theoretically magnify up to 75x without loosing any details.

## Step 3: Procedure

1-Paint all the parts as you like, but paint black from inside. for a better view.

2-Make holes in all PVC pipes as given in the photos according the size of bolts.

3-Then attach the medium sized pipe with the pipe cap as given in photo. Then join the cap with with big PVC pipe. Then join the lens with the pipe and your telescope is ready.

I need a detailed description of the apparatus you mentioned.
Can you please tell me the diameters of all bolts, 3 pipes, objective lens and eyepiece.
I know it's not meant to be a fixed size
But if you share your measurements, it'all be alot easier for me.

Very nice, simple but useful and instructionable. Outstanding. Semper Fi

Back in the late 1980's, I built a similar refractor using instructions from S&T Magazine. It consisted of a discarded photocopier lens, PVC pipe, garden hose clamps, and the like. It's simple but useful, and I still have it. http://www.panix.com/~reynolds/astronomy/copyscope/

If you don't use a achromatic or apochromatic lens I would use a colour filter to avoid blurry edges caused by chromatic aberration

Nice. Building your own telescope is the perfect project for young astronomers. I am going to have to try this with my son.
