I encountered this. It appears to trace wide arcs and then the pointer jumped 180°. I thought it was cone error preventing me from pointing at NPC, but I recalibrated that and I wasn't that far off.

Supernov that's exactly what happened to me but I did let it finish the movement and noticed the wrong place on kstars. Then I made a second alignment and like you, it worked.

Ihoujin I noticed that jump too. When it reaches very close to polaris it jumps 180°.

Well, I should have known that slewing uncalibrated mount near the pole might end up in odd discontinuities like this. I will try to test it tonight and see if I can figure out a way to do it properly and safely. If not, I'll disable the auto slew and just advise the user to move the mount closer themselves.

But thing is, I know the NCP was in view I wasn't that far off. And yes I have to test the accuracy in another way but guiding at 0.3" afterwards sort of tells me it was bang on. :)

Hi Jasem, first the align model is working very well, I have checked that with PHD2 drift align and I am really closer than I was before.
Also I can make longer exposures without drift. I was guiding with 0.5" (both RA and DEC) and now I am on 0.4" (RA)/0.2"(DEC) so I it's really a big improvement.
The issue is only the first positioning of the mount, If made manually there's no problem. Thank you for this method, it really helps.

I tested the alignment method yesterday. Just a simple remark. When a slowing orientation (west or east) is chosen at first rotation it remained not set at second rotation.
Anyway I didn't had enough time to test the accuracy as the clouds went to ruin the rest of the night.

You mean if you select "Auto Mode" then 2nd rotation does not follow first rotation? If that's the case then it is already fixed in GIT.

No I mean that if, manually, I choose east direction for first rotation, at the second rotation west is checked instead of east.

Thanks, just committed a fix in GIT for this.
