Hi,
I recently acquired a Wild (17250?) and I am struggling to focus the 100x objective.
Woul also like to add a micrometer to the Nikon huygenian 10x eyepiece to measure mushroom spores.
Any advice?
Keep safe!

Welcome Dennis,
The 17250 on your Wild is probably the serial number. If all your objectives are also Wild, it shouldn't be hard to focus from one objective to the next. The 100X is usually an oil immersion objective and you would need a drop of immersion oil between the objective and coverslip. To get the objectives to focus, what I do is start with the 10X and focus on a specimen. Then you rotate the next power objective 20X or 40X and if the objectives are all the same make and type, it should be pretty much in focus and may just need a tweak of the fine focus. After the 40X is in focus, swing the 40x our of the way and put a drop of immersion on the slide and then swing in the 100X objective. Again, it should only take a tweak of the fine focus to get things in focus. Once you have oil on the slide, you need to be careful you don't swing the 40X or other objective in the immersion oil as it could ruin your other non-immersion oil objectives.
Do post a picture of your Wild microscope.

Also, the 100x objective may be obscured by old dried oil on the specimen-end lens, a common problem which can be cured by cleaning with lens cleaner now and after each immersion-oil session.
