1, 2, 4 - epi
3 - immersion from the second photo in the GIMP program
5- autoFL UV (A white pad under the fly, because the eyes shine like small flashlights.
Only eyes would be visible against a black background)
More questions! I have the equipment for fluorescence but have not done anything with it, so looking for whatever guidance you might have (it appears from your photos you have done quite a lot with fluorescence!)
What light source are you using? Do you need to take an6y special precautions for the UV?
