Polemaster final alignment help

(1/4) > >>

Alex Miller:
I'm using a new Polemaster for the first time. First steps are super easy. But when I get to the final alignment the red circle (pole) and the green box (axis) seem to move together (excepting for the fact that if I move the alt or az, the two white boxes (stars) and the green box start bouncing all over). Nothing like this seems to happen in any of the many youtube videos on the subject.
Sorry about the poor quality. Its dark and 2/-17 degrees. But wherever I move the red and green get no closer!!!

bayretide:
Aside from a potential software bug I can't see a reason for this to happen due to software malfunction.

Things to check-

Polemaster alignment should be done with your mount completely powered down.  With PoleMaster you are doing a physical alignment only so should not have your mount powered up and tracking in anyway.

The screenshot seems to imply that your rough alignment was a fair way out ....as the red and green boxes are usually much closer at the end of rough alignment based on my experience.

Double Check your initial rough alignment steps. Does the selected star stay properly on the green circle as you rotate your mount?? If not your rough alignment is out.

Final precise alignment only takes very fine movements in alt & az so making big adjustments might overshoot.

Hope this helps

Poor seeing conditions, it's normal and not a software issue.

Mount off. Manual rotation of polemaster shows star tracks green circle nicely.

Rough alignment goes smoothly - and looks far more accurate than screenshot above. Then things get wacky as soon as I go to the next mode.

I'm quite certain its NOT poor seeing. I did this two nights in a row. First time I've ever used it. I could see some flickering of the stars on the screen last night, but they look very steady tonight. The two white boxes lock onto the stars nicely unless I move them too far then they just bounce all over.

Is there anywhere I can download prior versions to see if this is some sort of bug?

Very strange.....Looks like the Mac version you have???

I have just used the latest version on a MacBook Air 2013 Model and it worked perfectly with my setup.

There is always the chance you have some sort of bug or issue with your specific laptop setup.

Could also be bad seeing but even with bad seeing you would expect to see both boxes moving together as you slowly adjust alt & az but you are saying that they are not moving together at all and bouncing all over??? which if seeing was that extreme to do that there wouldn't be much point to attempting it anyway until you have good seeing.

Also there is a box to tick on or off to compensate for atmospheric refraction.

The only other thing I can think of is if the star you have chosen is incorrect.....which would cause this problem
