40$ USB super telescope, easy to make, sees craters on the moon

40$ USB super telescope, easy to make, sees craters on the moon
Turn an old telelens and a webcam into a powerfull telescope that is capable of seeing craters on the moon. Next to the webcam and tele lens all you need are some standard pvc plumbing materials (pipes, diameter adapters and endcaps)

Needed materials
Here's what you need:

1. A webcam (I used a quickcam 4000 from logitech I still had)
2. A telelens, the more focal length the more magnification you'll get, the lens I'm using here is 80-210mm, you can get them at ebay starting from 12dollars. Many people have old tele lenses left from the analog camera era so there are plenty of them on the web.
3. Some standard pvc plumbing materials: pvc pipes, a diameter adapter to fit different diameters and some end caps. What you need precisely depends on your lens. More details on this can be seen on the next steps.
4. It's not part of the telescope itself, but it is important to have a tripod since the magnification is very large so any movement will ge greatly magnified. So without a tripod as a stable base, you won't be able to use your telescope.

Wish I had seen this and made one before the night Jupiter was so close. Wonder if it would have gotten a good shot

This is interesting. I've already got a beautiful telescope (114/90, more or less like this one: http://image.made-in-china.com/2f0j00MvaEwhQIaUbC/Telescope-F900114A-.jpg), maybe I can put a webcam and use it with the PC. What do you think about it? I think a good webcam is needed, but I don't know them. Can you give me an advise? Thank you very much!

Good project, I've put a Logitech 510 web camera behind a 75-300 mm lens and while the resolution is good, there is a bright section in the middle of the image.
Any ideas of how to disappear it?
Cheers

The bright section that you see is possible to be flare. Your web cam see a reflection of it self in the last element of the lens. A solution might be to cover your web cam with something black that does not reflect light.
Nov 1, 2011. 3:43 PMwhenu says:
Thanks for the suggestion, doesn't seem to have made a difference but have eliminated most of the bright spot by zooming in with the software that came with the camera, cheers

you could use ManyCam, it has a lot of nice options for adjusting different things with your input.

I'm looking to build something similar to zoom in on small objects from about 8-10" away with live video through USB.

Would this lens and setup work for this purpose? If not what lens would do the trick?

Woops. Spoiler.

I decided to modify it abit, I replaced the webcam by a socket to install my cel phone. So I can have a "live view" directly on it, from my cel phone camera. It work nice, but my phone some time have a hard time focusing.
Mar 21, 2008. 3:50 AMFrank Strudel says:
Do you know of any software that shows a decent quality full screen live view from USB?
Nov 28, 2008. 1:20 PMlgcalex says:
its not software, its hardware. Buy a better webcam, read reviews. cheap webcams means crappy video.
Jul 1, 2011. 5:28 PMlukeyj15 says:
But after that, i think he was looking for something that will show the video in real time.
Dec 2, 2008. 9:12 AMFrank Strudel says:
Yes, but i have no means of accessing any live video from a usb video device on my computer, do you know of any programs to do this. Sorry for not making this clear.
Jun 6, 2010. 2:50 PMtopper2 says:
the hardware that you buy should have a driver with it ( usually a mini disck) this is so the computer will know what to do with the new hardware. it usually comes with a software to take videos also.

Best free webcam software I've found is Yawcam - http://www.yawcam.com/
Dec 2, 2008. 11:20 AMharry_osullivan says:
camera software called bison cam, or software usually given with webcams AMCAP or something like that...

I recently built this, thanks for the great 'ible. I found when pulling of the webcam's focus ring that mine had tiny orange filter on it, this needs to be included or, as I found out on my original tests the colors are washed out as the reds have been removed (I think other 'ibles have said to remove it and make an IR cam). Check out my pic taken from Melbourne Australia at 6:30PM Sept 13, 2008!!!

I need me on of those PRO patches. So elegantly put next to the name... I'm so ashamed.

I don't really notice it to be honest, so there's nothing to be ashamed about.

Well you have a cardgame named after you. Thats impressive. Sorta. Well done for your contributions.

GREAT shot. Curious...what MM lens did you use?

Very nice Instructable. However, that particular lens is way out of my price range. Can I attach it to a department store telescope somehow?

u can go to and thrift store to find these dlsr camera lenses, i found many for $5

I just finished building mine. I am stunned by the abilities of this mod. This is waaaaaay cool.
Aug 18, 2010. 3:43 PMmartzsam says:
I came across this while browsing, and I when I saw the parts list, I looked at my web-cam, my old film SLR, my old tripod, and a stack of PVC, and I almost exploded. Awesome project!
Jul 18, 2010. 12:53 PMjamesfd2 says:
...still working on mine. Started with a Nikon back lenscap to simplify mounting. BTW the focus plane is 46.5mm behind the lens mount on nikon-mount lenses. The CCD in my webcam is so tiny that at 30' a 50mm lens on the sensor creates an image of a doorknob that fills the frame.
Jul 15, 2010. 6:15 PMNCBob says:
Simply awesome. I built this with a very cheap web cam and a Kiron 300 mm telephoto lense I had on my K-1000. At first I had the sensor WAY too far from the back of the lense, after re-reading the instructions I removed the majority of the distance and just holding it together and holding it by hand I was able to see some craters on the moon. I can't wait to get the right length PVC and make it permanent and also install it on the tripod I have. I only had the zoom at about 100mm and was seeing the moon in the entire screen. I also have a Clique HD webcam that I think I'll sacrifice for the final version, the cam I have now only has about 320x240 resolution, and only has 640x480 by interpolation. The Clique has native 1280x1024. As soon as I get it put together and have some pictures I'll definitely be posting them. Great instructable!!!!
Jul 15, 2010. 8:44 PMNCBob says:
Here's my first pictures, I still have it just a hair too long so I need to cut it down just a bit so I can get good focus. http://public.fotki.com/NCBob/hobbies/astronomy/usb-telescope-v1/moon-first-pictures/

Loved this instructable. I have two old lenses here at home, 75-250mm and 75-300mm that I'm using this for. Here's the first shot I took from my 250mm lens - next step is attaching the CCD to my telescope for a closer look (I tried taking a picture of Venus, but it was just a brighter dot :P). The two black dots are artefacts on the lens itself that I only noticed afterwards (sorry, conspiracy theorists!) Taken NW NSW, Australia on 19th June, 2010 at around 7:30pm.

Hey Hanzablast! Really nice use of out-dated gear. You done good.

The best part is the webcam. Now you can spy on your neighbors from anywhere in the world. :)
