I’ve searched the forum and found a similar post from 2015 but not exactly what my problem is. I’m using EQMOD 2.00q on an HEQ5 mount and the latest SGP. When I’m imaging in the south my meridian flips work perfectly. When I’m imaging in the north around Polaris my meridian flips DO NOT work if my target is to the west of Polaris. The “time to meridian flip” value is N/A. It makes it very difficult to image targets like NGC7822 as it rotates around Polaris. It seems to have something to do with the DEC value. If DEC is to the north of 90 degrees my time to meridian flip is N/A and it will not flip. If DEC is to the south of 90 degrees I do get a correct time to meridian flip and it does flip. All the time EQMOD is reporting a correct “time to meridian”.
In this image I set the RA axis to what you see in the photo below. The DEC axis is 10 degrees south of 90 degrees. Notice EQMOD and SGP look good. Meridian flip will happen.
In this image I simply moved the DEC axis north 20 degrees. So now it’s 10 degrees north of 90 degrees. No more meridian flip and mount will stop tracking when it hits the limits ruining my night.
Here you can see the position of the mount. EQMOD is reporting a couple minutes to the meridian. SGP is reporting N/A. If I let it continue it hits the EQMOD mount limits and stops tracking.
What am I missing here? Is this a EQMOD problem or a SGP problem? I tend to think SGP because EQMOD seems to be aware of where the mount is. PierSide appears to be reporting correctly.
