Maximum weight for CG-4?
Posted 21 February 2009 - 02:54 AM
According to the manual for the XLT 120 refractor, the OTA weighs 12.5 pounds, while the counterweights are 7 pounds for the big one and 4 pounds for the skinny one. This is a total of 23 and a half pounds.
I'd like to add a guide scope on top of my XLT 120, but I'm afraid that even without a guidescope it may already be pushing the mount's capacity. I'm considering a Meade 70AZ for manual guiding, but perhaps it would add too much weight to the mount?
Short of getting a stronger mount, what would you advise with regard to guiding on my XLT 120?

As for tuning up the mount... what kind of grease, specifically, would you suggest?

I don't think there's much question that the mount is not going to be rigid enough for long-exposure AP using the setup you are planning, but that doesn't mean you can't try it anyway.

OK. So it's likely the grease on the CG-4 isn't as bad as it used to be. Do you think there's no point then in regreasing it? What about smoothing out rough edges in the gear mechanisms? Would that help make it more stable for use in long-exposure AP? I'm not sure I'd like to try that (afraid to damage the mount) as opposed to just re-greasing it, but I won't rule out the possibility.
