Swapped RA Gearbox to Dec,,,,,only change I see is the periodicity of RA looks more like a saw tooth, Still have RA RMS at 1.6 Also removed all end play on RA and slacked up the worm to have a little

Re: Help with DEC backlash/jumpy guiding
Hi Magnus, When you moved to another object, or did a meridian flip, the problem went away or got better. So I consider 2 possible causes. One is the DEC of the mount, and the second is the guide

Re: Help with DEC backlash/jumpy guiding
Hi! Yes, I'm interested in working on the mount, finding causes that I can eliminate. I already do as you say, run latest PHD2 and use GA etc. The major problem here, is that it is intermittent...

Re: Help with DEC backlash/jumpy guiding
That's definitely a possibility too My experience is pretty much all Losmandy mounts have a certain amount of DEC backlash so my thought is it's easier to first make sure the guiding is set up

Re: Help with DEC backlash/jumpy guiding
I¡¯m not sure that agree that it¡¯s a PHD problem. He¡¯s talking about severe DEC backlash. This sounds like a mount issue. Rob Get Outlook for iOS<https://aka.ms/o0ukef>

Re: Help with DEC backlash/jumpy guiding

Help with DEC backlash/jumpy guiding
Hi! Lately, I'm experiencing bad guiding in DEC on mu G11. It's OK in RA and at times also in DEC, but unpredictable (so far). Good means a RMA of about 0.7 arc secs. Bad means RMS over 1.5. I use

Re: Need Help with Gemini 1 Movements
Thanks, Dave . . . good point! Michael, you may have hit on the problem. Since the drives work fine in Sidereal mode, and since the Gemini looks fine until the mount needs to actually move, the

Re: G11 Guding PHD2 rms number High G1
Hi Greg, Some actions to try: I think you said your RA has the high precision Ovision worm system. So Chip's comment about the brass Losmandy worm does not apply to that. I don't have an Ovision worm

Re: G11 Guding PHD2 rms number High G1
Hi Greg, A couple of thoughts on your process. You are not likely to get very low tracking error numbers with the stainless steel worms, you must have brass worms for the best precision and tracking.
