I suppose that you are unaware that there are more than a half a dozen
minerals that qualify under the term "asbestos".
Only a few of them exhibit the needle morphology and are therefore
considered dangerous.
The criterion of "needles" actually fails to detect many forms of asbestos.
Here is some information on this subject.... and you can google up a lot
more.

You are making a very good decision to not buy a "toy" microscope. It
will open your eyes to a lot.
