StarSense Setup

Last night I attempted to perform another calibration. I used Arcturus as the calibration star. After doing all the initial steps to align the star, I performed the repeat step and the telescope slewed directly to Arcturus. At this point I thought the calibration was successful. Next I used the Goto function to find Vega. This time the telescope went beyond the star and would not stop slewing until it was parallel to the ground. I have followed the directions in the use manual, contacted Celestron directly and followed their instructions and I still cannot get it to perform as expected.  Tried again on another clear night and performed the setup/calibration while viewing the Celestron tutorial on my laptop.  Did everything step-by-step according to the tutorial.  Still was not able to complete the calibration/realignment step.  Will give this one more try the next clear night.  If that does not work I will have to return it.

    When you refer to calibration, are you talking about StarSense camera calibration as opposed to StarSense star alignment?

    We have recently learned that if SkySafari sends the time & location to the mount, this will invalidate the StarSense alignment.  If you have "Set Time & Location" enabled in the Telescope Setup settings, try turning it off.

    If you are really talking about camera calibration, then I don't know.  You said the GoTo to Arcturus was successful but the one to Vega was not. Are both of these being done from SkySafari?

    Bill- Thanks for your helpful comments.  I am not using SkySafari to do any of the procedures related to the StarSense setup. When I refer to calibration, this is the portion of the setup procedure that calibrates the center of the telescope optics with the camera.  As per the directions I let the StarSense camera go through its auto alignment procedure.  When this is finished I use the GoTo function to locate a star to calibrate the optics.  After entering a star I allow the telescope to slew to where it thinks the star should be.  As always, it is out of view in the eyepiece.  Before making any adjustment to bring the star into view, as per the Celestron tutorial, I make sure that I am back in StarSense calibrate mode. At this point I use the direction keys to make the fine adjustments to bring the star into view.  I then press Enter and replace the low power eyepiece with a high power one and complete the procedure.  After pressing Align, it should be calibrated.  When I perform the realignment, the telescope slews accurately to the star I used for the alignment calibration.  When I enter in a different star, the telescope does not find the star.  I am going to try this again tonight and will follow the directions and tutorial very carefully while I am doing the alignment and calibration.

    I think you must kickoff the StarSense alignment from within SkySafari, not via the hand controller.  It is not clear if that is what you are doing.

    My Celestron contact says:

    "His results are a bit strange from what I am understanding. It would be helpful for him to contact our tech-support team as they can walk him through the entire process and will be able to spot if he is doing something that he shouldn’t be doing."

    Celestron will provide support for Celestron Wi-Fi in SkySafari so they should be able to help you.

    Bill- I have SkySafari installed on my iPod, but I have no WiFi to use it to control the telescope.  Nothing in the manual or the Celestron tutorial say anything about needing SkySafari to get StarSense to work.

    You can certainly get StarSense to work standalone.  However, if you want to control the scope from SkySafari, I think you need to do the StarSense alignment from SkySafari.

    So are you saying that the problem is not when you are using SkySafari?  Is this a pure StarSense issue? If so, why are you posting on the SkySafari forums?
