Re: Understanding a GM8 for Possible Purchase
|
Hi Jeff
these look like the high torque servo motors. your seller should be able to confirm this
other than the tucked in motors, the big missing item is the spring-loaded worms, which are imo probably the most significant mount improvement in the last handful of years.? You won't have to think about east biasing your weight and it does a great job of minimizing backlash as well. Generally you won't need to reset your worm gears either.?
In this regard it's probably one-or-the-other choice - sending in a G8 for the upgrade is probably more $ than if you just bought a new mount.?
you would of course want to know the history of the mount upgrades, any issues the seller has had with it, has it been dropped or roughly handled, etc. look for unusual marks or scrapes. It does have the LW?tripod spreaders which are an additional accessory when buying new.?

Hi all.?
I¡¯m on the waiting list for a GM-8G, and a used opportunity has come my way.? The mount was made pre-2011, had Gemini-1 and has been upgraded to Gemini-2.? It¡¯s also been upgraded to OPWBs but they are not spring-loaded.? Current owner does not know which motors are on the mount but says it slews as fast as any GOTO he¡¯s used.? I¡¯ve attached a couple of pictures.? It appears to have been well-maintained
I have three questions: ?
1.? Can you tell which motors these are??
2.? What material function and convenience would I give up choosing this mount over a new one? ?(I see these are not tucked-in motors and appreciate I¡¯ll need to watch for snags and bumps, and be extra careful moving the mount.)
3.? Beyond the details of its features and what the seller knows about maintenance, what else should I be asking?
Thanks for your advice!
Jeff
