I have always had the longest objective in position (pointing down), then lowered the lens to what I thought would be close to a good focus. This way, you can rotate the turret to the shorter lenses, and be assured that the lens body will not strike the stage or slide.
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
The lowest power objective lens should be in place when placing a slide on a microscope stage. This allows for easier focusing and initial viewing of the specimen at a lower magnification before switching to higher magnifications.
The objective must be in the upper position when removing or placing a new slide on the stage of your microscope. This prevents the potential for the lens to hit the slide and possibly damage both the lens and the slide.

Storing a microscope with the low power objective in place helps to protect the more delicate high power objectives from damage. The low power objective serves as a barrier, preventing the higher power objectives from being accidentally touched or bumped during storage, which can affect their alignment and performance.

If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
The magnification of a microscope using the 40x objective is 40 times the actual size of the specimen being observed. To determine the total magnification, you must also consider the eyepiece (ocular lens) magnification, which is typically 10x. Therefore, if using a 40x objective with a 10x eyepiece, the total magnification would be 400x.

The objective lens of a refracting telescope needs to gather as much light as possible to see faint objects in the night sky, so a larger lens helps achieve this. In contrast, the objective lens of a compound microscope is designed to magnify specimens that are already well-lit, so a smaller lens can be used effectively.
To properly put a microscope away, first, lower the stage and ensure that the lowest power objective lens is in place. Next, remove any slides from the stage and clean any used lenses with lens paper if necessary. Then, wrap the power cord neatly and secure it, followed by covering the microscope with a dust cover. Finally, store the microscope in its designated location to protect it from damage.
Turning the nosepiece to the lowest power objective (LPO) before putting the microscope away reduces the risk of damaging the objectives and slides. This position also helps to protect the lenses and prevents any debris from accumulating on them during storage.
The higher power objectives are longer and can result in scratching the lens the next time someone uses the microscope. It also encourages the user to remove any slides that may have been left which they otherwise would have missed.
I must have left my microscope in the car.
