Ekos polar alignment backwards?

Hi all,

Anyone use Ekos for polar alignment? I just tried my first polar alignment using Ekos. Not sure if it’s a new record, but it’s taken me about 4 hours. The reason being because it’s my first time, I didn’t know what to look for when the routine kept failing me, and because Ekos seems to have the correction vector backwards!

Watching the official YouTube video describing how it works, Jaime says the put the star on the end of the correction vector, and move it into the crosshairs. I did that for over 3 hours, wondering why every time I redrawn it, that my alignment seemed to be getting worse. The it finally clicked. If it kept getting worse instead of better with each iteration, the it was pointing in the wrong direction. So I simply started reversing the vector, putting the star in the crosshairs and moving it to the other end of the vector, and lo and behold, I now have an alignment with 26 arc seconds of error, instead of the 2-3 degrees I’ve been struggling with all night.

So, has anyone else noticed this? Is it possibly a Southern Hemisphere thing? Is there a setting I should be putting somewhere, or is it just a bug that I haven’t found reported elsewhere, so I doubt it).

Russell.
