Re: GM8 Guiding near meridian
|
Hi Charlie, First, I am glad you said that your guiding up to the meridian was excellent.? That says all of your hardware and software and electronics are working perfectly. ? When you are pointing at the meridian, the scope is on its maximum lateral extent and the counterweight is at the other end.? If there is a weight imbalance between them, the RA motor and clutch must exert the highest force at that position.? When you are at CWD, there is essentially no force on the RA axis or DEC axis, as these forces are taken up by the mechanics of the bearings. ? Secondly, check your cabling, etc for any snags...those are common issues in the dark, as the scope is moving things can snag up. ? Third, check your clutch holding ability.? If you bump your scope does the RA or DEC axis move?? If so I'd be wary of the small 3 inch OD 1.25 inch ID clutch disks of the GM8. ? I have made far better holding clutch disks; if interested contact me. All the best, Michael On Mon, Sep 25, 2017 at 2:27 PM, cbradshaw1@... [Losmandy_users] <Losmandy_users@...> wrote:
