Title: £10 Telescope
Post by: Whitters on Dec 08, 2003, 06:03:00
Saturn's rings observed through my £10 scope. The scope was a 200mm f3.5 Tamron lens I bought from e-bay for £10. There were a couple of dings on the inner surfaces so not much good for photography. However a bit of wood, plastic tube, electrical tape and glue, and I have a wide field telescope. giving a 7deg field with a 18mm eyepice. Using a 20mm eyepice and a 5x barlow the rings of Saturn are easy. I'll bring it to the next observing session.

Paul,

Did you use and adaptor to get the lens onto the barlow and eyepiece?  

I have a few camera lenses of 300mm+ focal length and wondered how I would get an eyepiece on one?  Or was this a m42 threaded version?

Can you let me know.

Hi Chris,
I think that you can buy adaptors for M42 thread lens.
However mine was bodged with a bit of wood like a polo which will be glued to the back of the lens, a short pice of plastic plumbing waste pipe, long enough to reach focus. Then to get the inner dimension of the waste pipe the right size I wrapped electrical tape round a 35mm film pot. Then lashings of epoxy glue and more electrical tape and there you have it.
