I also have a GM811, which I received new in March 2022. I typically have RA/DEC guiding at ~1.5 ratio (or worse), with total RMS typically about 0.8 arcsec. I’ve occasionally gotten my total RMS

Need troubleshooter and NINA logs, Sean. There’s nothing to go on, except for your reports of intermittent unexplained behavior.

Update v41b Several nights without issue, and then we had a clear night so I went to do the usual routine. Except this time the problem re-occurs, I had M81 in Framing and selected Slew & Center, and

Just FYI but I also have a GM811 and also get 1.5-2.0x difference between RA and Dec. I’m still on L5 though and usually my RMS is around 0.8 or so. Dec goes as low as 0.4 but tends to be around

Interesting question.? Mine has been the same since I got it, with RA about 1.5x that of DEC.? I get some elongation in the stars, but not too bad as long as my guiding is below the image scale.?

Pretty sure the set screws are still imperial 1/16th" (1.5875mm). 2mm is 0.0787". Although my cheap 2mms mic out to 0.0753". 1.5mm may work, if that 0.0035 thirty-five ten-thousandths of an inch isn't

The PE did improve with PemPRO, but I'll have to dig up the logs for details and get back to you. -- jamie.amendolagine@... https://astropifi.blogspot.com/

Hi Jamie, What is your imaging/guiding set up? What does PE look like before and after PEMPro correction? Do you have any guiding logs with low RMS value but with RA being 1.5x-2x greater than DEC?

Genius! Thank you John. Clear skies

Yes, Ryan. You can take a 2mm(?) Allen wrench and chop off about half of the short side of the "L". Then file and sand it until it is square and smooth again. I have this special wrench in my Losmandy

Hi everyone. I'm back from the eclipse trip, happily imaging with my GM811G at L6. For the most part everything is going great. Seeing has been really good lately and I've seen total RMS dip into the

Good evening, Had some worm/ring interface chatter that was growing worse over time (with worsening guiding) and I had a couple of spare hours today so I decided to clean and regrease my RA axis (DEC

This is a common problem. Several people have improved this issue with good results. Michael Herman has been key among them. Just reach out to him and see if he can help. -- Chip Louie Chief

To be clear, you are talking about the center of the 3 ~1inch diameter gears on the outside, that you can access by removing the cover plate correct? ?I have not noticed a great deal of play in mine.

Good news is that I was able to select 3 targets and each time the mount was pretty accurate and no problems making corrections like before. Strange news is that my guiding was awful when selecting it

Hello, I have a G11T and I can play with that inclination, if I tighten the screw too much it does not turn without adding washers, I should have a small Teflon washer and be able to play with that

Sean, the troubleshooter should be run without all external software connected to Gemini. As I said , start Gemini.net and connect it to the mount. Start the troubleshooter. Don’t start any other

To update: Woke up and saw the skies were clear (enough) that I went out. I did not polar align or anything, just slewed to M81 and started to guide. I had changed the settings from Visual to Photo in

So, this has my attention, mine is set to Visual also even though I have not officially done any guiding yet. I am wondering what the differences are between the 3 settings.

No it’s good you replied with a fix rather than leaving the thread “unfinished”. ? This way others can gain knowledge. ? Way too many threads remain “incomplete”! There will be many
