I recently acquired a gently used Orion SkyQuest XT8i which seems to work great. This is to encourage my granddaughter's interest in astronomy which I recently discovered. Having only owned refractors in the past (distant past) I am curious about how to take care of it in a high humidity environment (East Tennessee). The scope is kept in an unheated garage to allow for quicker temperature acclimation.
First, I assume I should allow some time after viewing to allow humidity to dissipate before snapping on the plastic cover and putting the scope in its case, the question is how long?
Second, is a dew shield recommended for a reflector scope? I was surprised how quickly dew accumulates in our area.
