Hi all.
I had an opportunity the other night to try out the polar alignment function in Ekos and I have a couple of questions.
Overall the procedure worked fine, It solved the image, re-located and solved again and calculated the error (for both Az and Dec)
But when selecting the "Correct Az Error" (for az ajustment) It was hard for me to know what star I was supposed to center in my FOV. Does the module just select a nearby star that's close or does it select a star that stands out a little bit (a brighter star)? I could not single out a star that was a good candidate for centering.
I was however able to correct the aligment error by adjustning blindly and then doing another measurement of the error until it was within tolerance.
Also does Ekos when displaying the error (too far east och west for Az) account for how the image is oriented? A refractor and reflector give different orientation (backwards, upside down etc.) I'm not 100% sure but I think when it said too much to the east, I adjusted west, but then the east error grew instead. Adjusting to the east reduced the error. But as I said, not 100% sure I did this right. I was very tired at the time![:)]( ":)")
