Re: Need help with issue in RA guiding and Synchronous Pulseguide

Hi Peter, Did you happen to see my earlier thread on the gearboxes, where I found that the grease had completely dried out and turned hard? I assume mine was an isolated case and possibly even a case

Re: Need help with issue in RA guiding and Synchronous Pulseguide

I am not sure if you can see the worm wheel on yours but I can easily see it on my Mach1 which concerns me a little bit. I can see how easily dirt can get on the worm wheel. See photo

Re: Need help with issue in RA guiding and Synchronous Pulseguide

Hi Parijat, Oh I see. I don't see how dirt can get there, these gears are well protected by the box. Very strange that cleaning and regreasing these gears solved your issue. I hope this issue won't

Re: Need help with issue in RA guiding and Synchronous Pulseguide

Hi Peter, Not the worm or wheel (I did not remove the gearbox). Just the gears in the RA gearbox. There are 3 gears, a delrin one and two aluminum including the spur gear on the worm shaft. Here is

Re: Need help with issue in RA guiding and Synchronous Pulseguide

Progress at last! I took the 3 gears out from the RA gearbox, cleaned thoroughly and placed them back. Did not see any noticeable dirt in there but cleaned all of them re-greased anyway. And just

Re: Larger "diameter" Counterweights for AP-1600 ?

Thanks Howard, You are correct, I did get my "Latitude problem" reference, reversed. The weights hitting the pier, would be more likely for a concern with mounts used at LOWER latitudes,

Re: Larger "diameter" Counterweights for AP-1600 ?

Hi Joe, I'm assuming you got the latitudes backward in the second paragraph ... Anyway, it is a moot point with the 1600 since the azimuth adjuster is in the back of the mount. Mag. 7
