Re: How to train PEC
Brian, I noticed your comment about having a 42 second recurring error on your G11GT. A couple of weeks ago I bought the Losmandy RA-AXIS Titan module as an update to my G11. I have been having

Re: Help with DEC backlash/jumpy guiding
well i only mentioned it in pretty much all of my posts ;) I believe the source is in the tucked in gearing. As Ray mentioned he's working (finishing?) on a two worm cycle PE correction, which would

Re: Repackaged RA motor assembly

Repackaged RA motor assembly
Sorry in advance for a question that I'm sure has been asked and answered: Until now I've more or less ignored all the talk about the G-11 upgrades since mine has been functioning very well. But I was

Re: Help with DEC backlash/jumpy guiding
ok. you win. I never saw that written...til now. Thanks for explaining this new design. I'll stay out of this, and will look forward to hearing the cause and cure of the "42 sec" PE issue. Best,

Re: Help with DEC backlash/jumpy guiding
Magnus, A little backlash is actually preferred and is often better than no backlash at all. If your RA axis does not have any movement at all, the worm might be too close to the gear causing just a

Re: Help with DEC backlash/jumpy guiding
Michael, I know you are just trying to help, but Brian's mount is not a G11. It is a G11GT, as both Brian and Paul have already confirmed in their recent posts. Best regards, -Ray Gralak Author of

Re: Help with DEC backlash/jumpy guiding
Michael we're talking a G11GT - the 'T' is for the titan RA portion which is the 319 worm also I don't know about the regular G11 with tucked in gears, but i wouldn't be surprised if those added some

Re: Help with DEC backlash/jumpy guiding
Michael, Brian has a G11GT mount, which has a Titan-based RA and a G11-based DEC assembly. RA has a 270 tooth wheel, which translates into just under 320 seconds worm cycle. Regards, -Paul

Re: Help with DEC backlash/jumpy guiding
Ray, This is a quote directly from the Losmandy G11 mount manual, which says the G11 period is 4 minutes = 4¡Á60sec =240 sec, right? Here is the text, from the Losmandy website:

Re: Help with DEC backlash/jumpy guiding
Sorry Michael Herman, but I'm afraid you are using the wrong worm period. The worm period is about 319.1 seconds, over which a 42.55-second frequency repeats 7.5 times. This is not correctable using

Re: Help with DEC backlash/jumpy guiding
I am certain you are right... if you can identify which gear is the culprit, that should be also sent to the EQMOD group who made up PECprep to add to their G11 list. How does that 42 sec peak compare

Re: Help with DEC backlash/jumpy guiding
Michael I would be happy to show you the 42 sec interval. i have a G11GT, and I think the tucked in motors introduce new gearing ratios (probably true for G11G as well). This has also been confirmed

Re: Help with DEC backlash/jumpy guiding
Unknown on the new G11G system... but you have to understand the contributors to noise in the PE and PE error itself. It was thought that only the worm mattered, and that of course rotates in ~239.4
