The Omano is pretty cool microscope. I'm planning on doing a nosema check next weekend.
Did a sugar sifting yesterday, put tupperware beneath the hives and checked today.
The color and shape matched varroa, but when magnified it was a severed ant head...very odd
I counted 8 varroa under Hive 2
I've got an ant in Hive 3
I think a 20-40x stereo dissecting microscope would be better for helping my eyes recognize varroa for counts, but the higher powers are necessary for nosema.
