I have the same microscope- I also have found that if I clip a small sample of bud and take it intothe house for examination is best- I have no problem distinquishing clear from cloudy and the amber stand out well- outside in the field is difficult in some light and the tungsten bulb in the scope does warm things up a bit due to color temp of the light bulb- take some clippings , several from same plant and examine closely- take your time and you will see the different color stages of trichs- Good Luck and happy harvest
