I'll start by saying that I know nothing at all about microscopy but have always had an interest in learning. Now, I was given this old Bausch & Lomb microscope by my parents, who got it from a friend who was moving to a new home and didn't want to carry it. As you'll be able to see in the pics, it is old but appears unused. It even still has an inspection tag hanging on it. I've looked around a bit and can't really seem to find much info on the value of these things. If it's only worth a couple hundred bucks or less I'm going to keep it, at the risk of getting addicted to another debilitatingly expensive hobby. However, if it's worth more and/or considered collectible (possibly because of it's condition?), I would prefer to sell/trade it for astrophotography gear. Any info would be greatly appreciated.
Thanks in advance,
