Well things come across pretty dry in text so my apologies.. but when someone writes duhh.... maybe Im old but that used to be a sound you make when someone does or says something stupid... But for people who really are beginners I think it is more helpful spell things out clearly so that there is as little room for interpretation as possible. I know it always helps to have exact information. Like type of microscope, power etc. So my bad if i interpreted it as being sassy, but the general attitude in a couple answers here were on the sassy side.
b well
