As Alex mentioned I purchased a 7x35 scope, so playing with lunars again.
A few inputs of the lunars calculator puzzle me.
If I understand I am to enter pressure at sea level, yet at 600-800 ft above sea level the pressure is lower, so refraction would be would be slightly less. Does the calculator somehow adjust for this?
What purpose does height of eye serve? Is there dip in body to body observations? If above sea level then it could adjust pressure, but if I recall one of Frank's examples from Chicago, IL he listed height of eye as 6 feet. It might be relavent in altitude of body observations, but *exact* altitude of body does not seem to be critical.
