The servo motors get way louder at high speed.? ?That's basically what I mean by scream.? ? If you have a Gemini connected to a GM-8 mount, but Gemini thinks it is a G-11 (which is what happens

OK, after posting on the discord and not getting a workable answer I think I figured it out for myself.? This is not a NINA or Gemini issue.? It is a misunderstanding of the settings and process on

That's a new one on me. I've only heard my Gemini units sound their beeper when reaching a limit. I've not heard a motor at a high speed, not even at the fastest slew speed, "scream." I think you get

papagordygrapes, Hope you scope did not bottom out and collide with anything. My issue with this also seems to have returned after being quiet for a week or two. The Dec motor runs at super high speed

Previously I was looking at what was on the webpage. There I did not see all email addresses. However, they are visible in the distributed emails from the group. I would agree with you Alan, that an

Hi Brian, Thanks for your insight here. I do occasionally see DEC side move in sympathy to RA.?? As for something slipping, I'm quite certain everything is tight.? The helical focuser on the

When I mean "screaming", I'm actually talking about the servo motor screaming at high speed. This happened during tracking. I think this must be a electro-mechanical issue, and as Brian suggests, I

Hi Tony i have just a couple observations for you - sounds like you have a good handle on things so just the highlights: - your long guiding run looks quite good. RA and DEC seem to have a lot of

John- Thanks for the input, responses embedded below... The thing is that PHD2 is essentially showing bad PA, (through GA), but the "pulling" (while guiding), or drift (while doing GA) that would be

Thank you Brian.? I'll give Tanya a call in a few days.? I'm a bit bit right now building an observatory in South Carolina. Pete

Hi Brian - Thanks for your response.? Since you asked, I will provide the logs, however your time would certainly be better spent helping others who have already reached the end of their own

Pete my guess is your mount is circa 1992, especially with the Celestron branding If you are considering the Gemini 2 upgrade, you might want to call Tanya at the main shop number. She may extend the

Mount serial number? HGM9211145 It is branded Celestron https://photos.app.goo.gl/9yRTCjSwgxLFKXki7 I had a feeling that you would say that the RJ45s preceeded the DIN connectors. Once I have the

Hi Pete RJ style connectors preceded the DIN-style connectors (which are still in use today in the Gemini 2) What is the serial number of your mount? -- Brian Brian Valente portfolio

Hi Tony Can you share the guidelogs from your screen caps? i'm assuming if you have not yet done the unguided output, the PECPrep is a residual error, and not the raw periodic error of the mount I
