eu stiam ca este mai multa stabilitate, dar am gasit o astfel de discutie unde mai apare un avantaj:
 "The other big reason for doing this is that if you are polar aligning using an alignment scope in the polar axis housing it is much easier to get up to the eyepiece (particularly if you are kneeling on the ground) if you can come up between two legs from behind. A leg in the way facing south does not help."

alt raspuns:
"Simple answer: Yes, move the peg. It's nice to have a single leg "North". It is also more stable. I've had and seen near tip-overs with the two-legs forward configuration with some loads."

alt raspuns:
"A gem is usually more stable with the counterweight bar over a tripod leg, but one issue with this orientation is the possible interference between larger diameter counterweights and the leg. If you make the change take the mount through all it's possible motions (with the counterweight(s) in various positions) to ensure that you won't have any problems ... you don't want to find them in the dark at 2am. "

inca unul:
"Most of the weight of a GEM is concentrated at the north end of the mount. Thus, putting the couterweight bar over a leg makes more sense for safety and stability. Unless you live way down south, or use very large counterweights, you should be okay."
