For some time, yes. I put it back at some point when winds went away (maybe an hour or two after I started), which should have restored balance, but possibly sent PA farther off at the same time. Targ

So, were you imaging with the dewshield off and unbalanced? Rolando

Hi, For reference, I did calibrate near M3 which was the nearest I could get from the celestial equator/meridian at the time, given high trees that obstruct my sight in the south. But guess what, it s

#Guiding

The fact that both RA and Dec are drifting so fast in just a few minute's time indicates either that your polar alignment is way off, or that the object that you are calibrating on is not near the cel

Well, I'm not the one who will contest your analysis, Brian. As Howard said earlier, your advice is to be taken seriously, and I agree! 🙂 And I also agree with your argument about the guiding pulse be

Seb When i first reviewed your PHD logs, it appeared to me your polar alignment was quite off. All your corrections were in one direction You said you thought it was the wind, but i have my doubts abo

Ooops, not sure why the second photo showing balance in Park5 didn't go through. Please see attached. De : main@ap-gto.groups.io <main@ap-gto.groups.io> de la part de Seb@stro <sebastiendore1@hotmail.

Thank you Brian and Roland. While its not impossible that DEC balance was off for some reason, I would say it's unlikely as I usually do it the same manner Roland described and last night was no diffe

#Guiding

Hi Sebastian I meant things exactly like what Roland said - he suggested it was DEC imbalance.

#Guiding

Hi Brian, Just re-reading your comment above and I'm not sure I clearly understand what you mean by "basic correct setup". Are suggesting I should refine some settings within the imaging/guiding softw

#Guiding

This indicates a severe unbalance in Dec which puts a lot of pressure on the gear teeth and causes high friction. Check your Dec balance by sending the mount to Park1 or 4 or 5 and loosening all 4 clu

Hello Sebastien, I sent you an e-mail, please check. Roland

#Guiding

Hi Sebastien, First off, remember that the declination axis does not track unless a model is present, and then it would only be extremely slow. Dec spikes pretty much have to come from software that i

#Guiding

Thanks for your analysis Brian. What you see there is due to serious wind gusts present at the beginning of the run. I even had to remove the dew shield to help with that... But by 11:15-11:30PM, wind

PS i just found your PA run sorry i missed that the DEC is a little bit concerning here. this is without any motor running and 3 second exposures, and yet the DEC looks remarkably uneven, especially w

HI Sebastian I suggest you take this up with AP in their forums encoder mounts like the Mach 2 require some basic correct setup, and i'm not sure yours is there (i'm not suggesting there's anything wr

I seem to have some very consistant spikes (about 3" in magnitude) every 130 seconds now. I have monitored for about 20 minutes long and they are very predictable... Note that I have reduced exposure

Hi Brian, Thanks for your reply. Logs here: https://openphdguiding.org/logs/dl/PHD2_logs_BqZp.zip I should probably have added that my imaging scale is 1.04"/px. So it's probably impacting a bit, mayb
