I have always struggled to be under 1" before but tonight i have had a record. The graph has stayed under 0.6" almost the entire night !

Re: let me see your guide graphs!
Congrats on those results, that's very impressive. Most folks don't realize that to get results like that it is a team effort. You, the user, your mount, and PHD2 all have to work together to achieve results like that.
About showing you a picture of my POS guiding graphs, I think not. The last time I was out I could not get results below 2.0" RMS.
Please tell me your stars were round,

Re: let me see your guide graphs!
I am imaging right now too, but I am not going to show my graph because it looks pretty rough. Averaging about 1.5". Stars look pretty good though, so no problem here. Pretty much normal.
Well, I cleared it and here is a piece before the sawing starts! In fairness though, the seeing is poor.
Good for you! Keep it up.
What is your target? I am shooting the Flaming Star right now waiting for the Rosette to get high enough (>40 degrees) to start clearing the city
Great guiding man!!!!!

just joking, i was going to insert a hot pixel guide but i can't find any screenshots.

Re: let me see your guide graphs!
it's alright , typical .4'' to .7 '' it's really all i need (0.65'' imaging resolution) , images don't really suffer if the guide spikes to 0.7'' for half a second . i had a play with the backlash settings,worked out alright.

Re: let me see your guide graphs!
And it will also be interesting how the mount will handle a more heavier tube in the future. I will get a 130mm or a 115mm refractor for galaxy hunting. So if i will keep get these kind of graphs it will be a very happy But i think a mount upgrade will come either way i think.

Re: let me see your guide graphs!
I was able to get the best guiding after using the polar alignment feature, but it sure it time consuming. The slew rate can be increased but it reduce accuracy. This was after using the polar scope to get initial alignment and it was around 5' 30" off. Obviously I need better initial PA with the scope too.
Is 1'44" good for polar error? Seems still a bit high to me. I noted where the polar scope was after the final alignment as compared to the starting point and it wasn't that much.
What kind of additional tuning needs or can be done to the AVX? I've seen

I am not familiar with your software, but if you get guiding values similar to your posted graphic on a routine basis, personally, I wouldn’t change a thing. My guiding is usually challenging and as JT said, it is always better In the northern part of the sky.
Sometimes, I will shoot an image or two where the total arcsec rms error in PHD is under 1”. That is rare though. If I am between 1.2” and 1.5”, I am happy. From what I’ve read, this is typical performance from an AVX.
I have removed the two brass drive gears on both axis, buffed with a tooth brush and polishing compound and adjusted the clearance to minimum (no binding). I reduced tension on the
I am sure that I have some flexure, but I don’t fee like tackling another round of cable management right now.
I am very happy with the mount and can live with the guiding. I get pretty decent stars even when I am having a rough night.
For PA, I use Sharpcap. That is all that I use Sharpcap for. I have some bricks set in the ground to set the tripod legs on so I don’t use the polar scope anymore. Takes about 5 minutes to get 1-1 1/2”. I believe you are okay with up to 3” of PA error.
Didn’t mean to get long winded! Just my take!
