How does that help? This thread doesn't even touch on weight, and half of the content is from someone who has never even seen either of these telescopes. Own it guys- we've left a flaming wreck alongside the runway on this one.
Yes, I few of us do not own the LX600, BUT we do own a few shared components such as StarLock and the OTA. And the OP did ask about StarLock and the Optics.
Weight is in issue in this size class, but we all know that. I agree with Pak on keeping it outdoors and get a cover. I am using a Telegizmos 365 cover on my LX850; it should work fine for the LX600 and most other telescopes. I can't speak for how it will work in wetter climates, but I have read folks in Florida using them (soggy there). I would ask folks in wetter climates how their Telegizmos cover worked.
BTW - on a side note, I purchased my second product from Celestron: a 10lb VX counter weight for my LXD75. It fits! Oh, it was well packed along with the AstroTech Field Flattener. I now need clear skies...
