transportation can throw it out anyway.

I'm going to ask another 'silly' question here.(Please move if in wrong place Mike). Why does everyone's, (well it seems like everyone's, lots of references), DOB need to be *recollimated* after transporting to an observing site? Surely, if done correctly, with all these GS t'scopes with the lock screws etc *nipped up*, there would be no reason to RECOLLIMATE. I transport my Meade with no probs., & it doesn't have LOCK screws. Perhaps an article by someone who owns one????
An example??? Start with, undo the lock screws till they are almost out of the cell, CAREFULLY tighten down the 3 collimation screws till they *BOTTOM OUT*. Then back off 1 1/2 to 2 turns. Collimate normally from there. This puts max tension on the springs which should hold it in perfect collimation. ONLY IF YOU FEEL IT NECESSARY, just *NIP* the lock screws, but check the collimation again after this.
This should solve your *out of collimation* problems. If it doesn't, then buy a MEADE.

HTH someone.
