GPS Alignment Issue

[astrogeoguy]

Are you sure that you are in a magnetically clean location? Manmade infrastructure and even buried geology can bias the magnetic field. After the magnetic declination is accounted, does the seem to point at Polaris properly?

One thing I've wondered is if something is screwed up with the auto-align, where it ignores the magnetic declination (since it's kinda a fresh start, and thinks it's being smart w/ all the sensors). It's been a while, but I seem to remember auto-align working properly if I do "Calibrate Sensors" immediately before it. Polaris was still 10 or so degrees off for the calibration, but that's easy to find and center.

Same for me. Check out that "home sensors" flag in setup - telescope and make sure it's on. I reset mine to on, but have not yet had a chance to test if it solves the problem.

I wonder sometimes if the 15 degree errors that various people report for various mounts is due to incorrect entry of DST / time zone information. Let me explain...

I live in the Pacific Time Zone. During the winter, on Standard Time, I am UTC-08:00. In the summer, on Daylight Saving Time, I am UTC-07:00. It would be tempting, in the summer, to enter my time zone as UTC-07:00, wouldn't it?

Yet (on my mount at least, and I suspect on most), that would be incorrect. The correct setting is UTC-08:00, Daylight Saving=YES, even though my clock is UTC-07:00.

I have been suspicious of this for quite some time......besides being in my observatory now, I actually turn gps off, type in time, date, location manually, do not even consider for daylight savings.....Once one points the scope at proper alignment stars, it works fine no issues....mine works just as fine now with gps also....it seems quite a few years back the error disappeared after doing quite a few find home sensor iterrations, etc...local interference to mag field can cause issues like people are reporting.
