I finally was able to get a picture of a blood smear. I used a 10X objective and a 9mm focal distance. The only thing one can really see here are the red blood cells. But they look pretty normal; I don’t have sickle cell anemia. I think I need to see what I can find at a local bio lab in a community college in terms of higher magnification. And find some stain, and also work out the dilution of the blood, so that I can count. I tried once with saline and mg citrate, a laxative you can buy at the pharmacy, but the osmolarity was too high and the cells shrunk.
