@50centipede something very identical to this. i bought the cheapest one but couldn’t find which exactly i purchased. if the link doesn’t work, pm me.
it’s not so much as the type or quality of the microscope, but it is the ability to open a molt properly and shine light at every angle to spot the goodie parts. the smaller the molt, the more difficult because not only will the spermathecae and uterus externus be very small, but it’s more brittle than a molt from a larger specimen and it’s a lot harder to navigate with tongs/needle/pin/etc. it’s technique rather than tools that is most important. practice makes better
