Re: GM-8 feature
Greg, Nope. But if you have a good idea of what we can use them for I would go and see what fasteners fit in those holes. Chip

Re: Polaris alignment problem
Sounds like hardware, you might double-check all your mount connections and screws and tighten them sometimes i've found the screws to my tripod were left slightly loose B

GM-8 feature
I am curious about a feature on my GM-8... at the bottom of both the RA and DEC axis there is a flat with what appear to be two threaded holes. Were these intended for some feature? Or an artifact of

Re: Polaris alignment problem
I think there us a discussion in the "setting up your mount" area of the Losmandy G11 mount manual...or else download the manual for the Orion Atlas that also discusses it. Basically you have to shim

Re: Polaris alignment problem
Michael, The next goto was to Capella, a star that I had already used in my model. I was curious if something had shifted -- and it had. That is what made me stop, CWD, restart. Then I pointed it at

Re: Polaris alignment problem
Thanks. I have read about cone angle and have a mental picture of what it is, but have no idea how I would go about measuring it on my little scope, let alone correcting it. So the answer is no, I

Re: G1 on G-11 refuses to go to bright stars
Magnus, We've recently found some bad EPROMs that lose code data prematurely...sometimes in months. (They were supposed to hold for 100 years when I engineered them in 1985... ). So an easy test is to

Re: Polaris alignment problem
hey Greg, Just curious... When you mounted yor scope, did you test/correct for cone angle of the scope+dovetail? My reason for asking is that I think cone angle would be a T- pointing model parameter,

Re: RA rate drift (revisited)
Gentlemen, I was recently enlightened about polar alignment and drift in the two axis on the Astro-Physics group. The polar alignment most of us are used to is designed to provide minimal declination

Re: G1 on G-11 refuses to go to bright stars
That's not a bad Idea Michael. But the "interrupt" only occurs on goto slews not things like "park" slews. However, that said there is not much else to look at. Along this line of ideas......Magnus,

Re: G1 on G-11 refuses to go to bright stars
That¡¯s a great idea Michael. Perhaps another way you can test this is do the goto from the hand control unit and then unplug it when it starts slewing? Thanks Brian Brian Valente

Re: GM-11 general lubrication
That is true. The bolts that I am more concerned about are the ones that attach the mount to the HD stand and the locking screws. They are stainless steel, I think, and get fully tightened, whereas
