I just got the Amscope M102C microscope, and it is the first microscope I've operated. I decided to try to look at a fly leg at 40x magnification, but all I could see were the blobs in your eye you get from looking at something bright, as well as a few dots that appear to be on the lens. I tried focusing, cleaning (even though it was fresh out of its package), but I still couldn't see anything. It's so blurry I can't even make out any shapes. Could I please have some help?
