Aligning with the StarSense AutoAlign Accessory

Page 13 highlights

Aligning with the StarSense AutoAlign Accessory Before you begin, attach the StarSense camera to the telescope tube. See the StarSense AutoAlign manual for more information on how to do this. Attach the AUX cable from the StarSense camera to an AUX port on your Celestron mount. Make sure you have everything connected to the appropriate AUX ports before powering on the mount. - If you are connecting via USB (CGX and CGX-L mounts only), simply plug in the USB Type B 2.0 cable from your PC to the mount, with the StarSense camera connected to an AUX port. - If you are connecting via hand control, plug the StarSense hand control into an AUX port on the mount and plug in the appropriate cables, previously outlined in the manual, from your PC to your hand control. - If you are connecting via WiFi, plug in the SkyPortal WiFi module if your mount does not have internal WiFi. Make sure the WiFi switch is in the correct position, as previously outlined in this manual. After CPWI is opened and connected to the mount, CPWI will automatically search for the StarSense AutoAlign accessory. Once found, you will see the StarSense selection in the Menu: Before aligning using StarSense, the StarSense camera must be calibrated to the telescope optical tube. Calibrating the StarSense Calibration aligns the center of the StarSense camera's field of view with the center of the telescope's field of view. This usually only needs to be done once, unless the telescope is handled roughly during transportation. If you have previously center calibrated the StarSense camera to your telescope using the hand control or the SkyPortal app, you don't need to do it again with CPWI. Before initiating a StarSense center calibration, make sure you have the mount homed or at index marks. Alt/Az mounts should be pointing roughly North with the optical tube level, and EQ mounts should be roughly polar aligned. Next, select "Center Calibration" from the StarSense section in the Menu. You will be prompted to select a star in the SkyViewer, and then GoTo the star. Then, use the onscreen slew controls to center the star in the telescope's eyepiece. If the star is not in the telescope's field of view, use the telescope's finderscope to find and center the star in the telescope. NOTE: It is highly recommended that you use an aligned finderscope during this step, since the mount is not yet accurately aligned to the sky. Remember to use the UP and RIGHT slew commands to finish centering the star to provide the best pointing accuracy. Once the star is centered in the telescope's field of view, click "Centered" in the Center Target window. The StarSense camera will then take an image of that section of the sky to determine its position and the position of the centered star. If the calibration is successful, the Calibration window will notify that the calibration was successful. If the calibration is not successful, you will be prompted to select another star to begin the center calibration process again. StarSense Auto Alignment Once the StarSense camera is center calibrated to the telescope, you're now ready to perform a StarSense automatic alignment. Select "Perform Alignment" from the Alignment selection in the Menu. When StarSense is connected, you'll notice two additional alignment methods in the "Select an Alignment Method" pop-up window: StarSense Auto Alignment and StarSense Manual Alignment. Select "StarSense Auto Alignment". If the mount has home switches or sensors, CPWI will automatically move the mount to the home position. Otherwise, make sure you have the mount homed or at index marks. Alt/Az mounts should be pointing roughly north with the optical tube level, and EQ mounts should be roughly polar aligned. 11

Aligning with the StarSense AutoAlign Accessory
Before you begin, attach the StarSense camera to the telescope tube. See the StarSense AutoAlign manual for more information on
how to do this. Attach the AUX cable from the StarSense camera to an AUX port on your Celestron mount.
Make sure you have everything connected to the appropriate AUX ports before powering on the mount.
-
If you are connecting via USB (CGX and CGX-L mounts only), simply plug in the USB Type B 2.0 cable from your PC to
the mount, with the StarSense camera connected to an AUX port.
-
If you are connecting via hand control, plug the StarSense hand control into an AUX port on the mount and plug in the
appropriate cables, previously outlined in the manual, from your PC to your hand control.
-
If you are connecting via WiFi, plug in the SkyPortal WiFi module if your mount does not have internal WiFi. Make sure the
WiFi switch is in the correct position, as previously outlined in this manual.
After CPWI is opened and connected to the mount, CPWI will
automatically search for the StarSense AutoAlign accessory. Once found,
you will see the StarSense selection in the Menu:
Before aligning using StarSense, the StarSense camera must be
calibrated to the telescope optical tube.
Calibrating the StarSense
Calibration aligns the center of the StarSense camera’s field of view with the center of the telescope’s field of view. This usually only
needs to be done once, unless the telescope is handled roughly during transportation. If you have previously center calibrated the
StarSense camera to your telescope using the hand control or the SkyPortal app, you don’t need to do it again with CPWI.
Before initiating a StarSense center calibration, make sure you have the mount homed or at index marks. Alt/Az mounts should be
pointing roughly North with the optical tube level, and EQ mounts should be roughly polar aligned. Next, select “Center Calibration”
from the StarSense section in the Menu.
You will be prompted to select a star in the SkyViewer, and then GoTo the star. Then, use the onscreen slew controls to center the
star in the telescope’s eyepiece. If the star is not in the telescope’s field of view, use the telescope’s finderscope to find and center
the star in the telescope.
NOTE
: It is highly recommended that you use an aligned finderscope during this step, since the mount is not yet accurately aligned to
the sky.
Remember to use the UP and RIGHT slew commands to finish centering the star to provide the best pointing accuracy.
Once the star is centered in the telescope’s field of view, click “Centered” in the Center Target window. The StarSense camera
will then take an image of that section of the sky to determine its position and the position of the centered star. If the calibration
is successful, the Calibration window will notify that the calibration was successful. If the calibration is not successful, you will be
prompted to select another star to begin the center calibration process again.
StarSense Auto Alignment
Once the StarSense camera is center calibrated to the telescope, you’re now ready to perform a StarSense automatic
alignment. Select “Perform Alignment” from the Alignment selection in the Menu. When StarSense is connected, you’ll
notice two additional alignment methods in the “Select an Alignment Method” pop-up window: StarSense Auto Alignment and
StarSense Manual Alignment.
Select ”StarSense Auto Alignment”. If the mount has home switches or sensors, CPWI will automatically move the mount to the home
position. Otherwise, make sure you have the mount homed or at index marks. Alt/Az mounts should be pointing roughly north with the
optical tube level, and EQ mounts should be roughly polar aligned.
