How to Focus Your Microscope:  The proper way to focus a microscope is to start with the lowest power objective lens first and while looking from the side, crank the lens down as close to the specimen as possible without touching it.  Now, look through the eyepiece lens and focus upward only until the image is sharp.  If you can't get it in focus, repeat the process again.   Once the image is sharp with the low power lens, you should be able to simply click in the next power lens and do minor adjustments with the focus knob.  If your microscope has a fine focus adjustment, turning it a bit should be all that's necessary.   Continue with subsequent objective lenses and fine focus each time. 

Parts Of A Telescope

Let’s begin by looking at a basic diagram of an average reflector telescope on an altazimuth mount and tripod and do them in a numerical order. [pic]
1. Finderscope
2. Focuser
3. Eyepiece
4. Release Control For Mount
5. Mount Base or Mounting Plate
6. Outer Tripod Leg
7. Tripod Leg Extension
8. Tripod Support Brace
9. Accessory Tray
10. Tripod Leg Clamp
11. Mount Axis
12. Mount
13. Mirror Cell – Primary
14. Telescope Tube
15. Slow Motion Control Lock
16. Finderscope Eyepiece
17. Finderscope Bracket

These are very common telescope parts and will only vary slightly by telescope and mount style. For example, a refractor telescope eyepiece and focuser would be located at the back, while its primary lens is located at the front. An equatorial mount looks a little differently than an altizimuth, but it also works with axis, releases and slow motion controls.
