Re: ATM Eye relief
One could go to their optometrist and ask them to make a glass monocle
(it's got to be less expensive than a pair of glasses). Then, send the
monocle out for multi coating. A monocle could be worn in the traditional
way, close to the eye (eliminating eye relief/positioning problems), or
could be mounted on a clip at the eyepiece, as Dwight suggests.
By the way, I wear soft disposable contacts about 99% of my waking hours.
I have minor problems when observing--mostly due to the contacts drying out
for lack of blinking (the image blurs, and the focuser needs to be
readjusted). The solution in my case is to always carry rewetting drops,
or remove the contacts for the viewing session.
