Re: Article on Micrometeorites

I replied to your Facebook "mystery object" post with correct answer before seeing your post here (but I've seen previous posts in this topic before, so guessing was easy for me.) Lol - no worries Sergey - I just assumed you saw the articles on Amateur Microscopy FB page - like I did ;) Nice to mat...

What size is that or what objective/magnification did you use?
This one was fairly big compared to the other 2 - took the photos on stereo microscope - so no idea really what magnification - but this will give you some idea:

I'm amazed by the detail in these books, fascinating to think it was done in the 1800's.
