Re: Star Eccentricity Help

I'm poking around in your logs some, and I'm waiting to hear back from someone else I asked a Q about, but I can see your RA corrections are primarily one-sided at higher altitudes (and a corresponding increase in RA and therefore your eccentricity goes up), and as you get lower in the sky, RA corrections become more even on both sides, and your RA RMS and eccentricity both go down
My suspicion is mirror flop or something shifting in your equipment
