make the necessary adjustments until the two images match up.
Finder scopes often come out of alignment during transportation
of the telescope from site to site, so check the alignment before

the main telescope tube very tight.

the hills. Common sense prevails: as long as the telescope doesn't
bounce around, it won't get damaged in transit.
Naturally, you should be extra careful not to damage any bearing
surface, which could hinder the smooth movement of the telescope.
Carry the telescope tube and the base separately. For the 12.5"
model you will need a second person to assist you in lifting and car-
rying the individual components. Be especially careful when passing
through doorways with the optical tube: knocking it against the door
frame doesn't do the mirror alignment any good!
