Well his exposures are over 2 months time and yes that is what really tough about doing this. Usually you do 10 minute "subs" at a time then stack them in software to gather all the light from the different frames. If the scope varies by 1/32 of the width of a human hair anytime during the 10 minute subs the shot is ruined and you have to toss it out.
The mounts that guide the scopes for the pictures are insanely complex. And expensive for the really good ones.
