I'm posting this as a follow-up on [What to look for when buying a light microscope?](https://biology.stackexchange.com/questions/5470/what-to-look-for-when-buying-a-light-microscope). The answerer states that you would need to use a an inverted microscope to count cell in the hemocytometer(counting chamber).

I've read, partly, a book on lab diagnostics tests and it was not written that there. Moreover, they mentioned things about microscopes featuring a compound upright microscope both in words and picture.
