    Default Correct planet position after skyalign?



    I just got my Nexstar 8SE. Apparently I didnít nail my first alignment, because when I had it slew to Jupiter it was near the edge of my FOV. It was easy enough to correct the position and put Jupiter in the middle, but is there then a way to tell it to track Jupiterís path using my new corrected position? It would be nice to have that option while I work on my alignment skills.

    Once the alignment is complete the mount is tracking, if you move the target to the center of field the mount is still tracking.
    If it slowly moves out of the center the backlash may need to be set or you may be in the wrong tracking mode.
    Make sure it is in sidereal tracking rate.

    There a a number of things you can do to improve your alignments.
    Ensure very accurate time and location data is entered although locations are good for about 50 miles.
    Choose auto 2 star align and 2 stars with wide separation, no higher than 70 degrees and no lower than 30.
    Polaris is a good star for Alt Az mounts because it does not move.
    Ensure your fine tune goto is from lower left moving up into the centre of the EP. This considerably reduces backlash as the scopes weight is effectively taking it out in upward motion.
    Test for backlash during the day on a far away object and dial it out from the HC
    If your just viewing a planet consider trying a Solar System align.
    After a 2 star align you can use Sync command on another target to increase tracking accuracy in the area of sky you are looking at.
    The fact that you got Jupiter on the edge of FOV is a pretty good start, often the planets can move erratically and sometimes the nexstar can't keep up, Mars is one of the worst culprits.

    Don't expect to centre every object every time , once you fine adjust your tracking should be fine as long as other criteria has been met.

    Good luck, you have a great system.
