First real test last Friday night. Snake Valley. Grass was wet with dew soon after sunset. Scope very moist. Temperature dropped to around 3 deg C after midnight. Dripping fog was rolling in and out. My eyepieces were superbly dry and just warm to touch. No problem with dew formation or fogging up all night. I was able to cap them and pack them away at the end of the session. Checked the next morning and they did not need airing at all!
