Where on the internet can I find a good used microscope?

when a school or lab closes or upgrades inventory they might sell their old stock. Call stock rooms of major university bio department and ask them if they ever sell the old scopes after they upgrade a lab. But if you are not well trained in how to use and repair microscopes it is very easy to get conned into buying a lemon! That is why I do not recommend e-bay.  I am in the market for one myself.  I might save up for a new one to avoid these hassels.

You can use a regular camera, but only if your microscope comes with a place to attach the regular camera. Basically all research quality microscopes do have a place where you can attach either a digital or a camera which uses film as long as it is a SLR camera and you can take the camera lens off (you basically attach the microscope instead of the lens in front of your camera). If you use a film camera, you may have to work out proper exposure times and be very careful with proper focusing. With a digital camera it is easier to check as you can look at the image you just took if it came out OK. Normally you can also attach digital cameras to a computer and see a large version of the image you took on the computer screen. \nYou won't get any good images holding a regular camera in front of an eyepiece like where you put your eye. For one thing it is difficult to hold the camera consitently in the correct place. Another is that light falling in from the side will be bad for the image quality. I think also the size of the image there may not be large enough to allow you to take an image of a high resolution.\nThere are also cameras you can buy which you can put onto your eyepiece instead of the ocular lens. They give decent images.
