One thing to keep in mind on Spotting scopes or any other magnified optic from what I have found......The higher power that you use, the less clear it will be. This is due to heat waves, wind/dust, temperature, humidity, light angle, ect , that the magnification will pick up. Using higher power early in the morning or late at night when the enviroment is more still will help in using higher power.
I have found that if I stay around 30X or a bit more, I am very clear. I have Vortex Viper 20-60X80. My friend I hunt with has Swaro wide angle. The Swaro is a bit more clear then the Viper, but for my budget the Viper will work.
I still use my Binos pretty extensively to find animals. If the animal is too far away to tell what the antlers look like, or how many tines ect, then I go to the spotter. I dont use my spotter as a replacement for my binos.
I also have found that if I focus first at a lower power and gradually turn up the power and focus as I move the power up. The clarity seems to be better. One downfall I have is wearing contacts and they dry out quicker using the Spotter then using my binos. Not sure if its eye strain or air movement between the spotting scope and my eye.
