Note:
• Inaccurate polar alignment could result in trailed stars and field
rotation in your imaging device.
• It is not possible to use the SXD2 mount in the north latitude
over 70 degrees and in the south latitude over 70 degrees.
The polar alignment scope is a small telescope that is installed
parallel to the R.A. axis of an equatorial mount so that the polar
Alignment scope can precisely point to the north (or south) celestial
pole. Accurate polar alignment is essential for successful long
exposure astrophotography of deep sky objects with the equatorial
mount. Check longitude and latitude of your observing site with a
GPS system or a map before the polar alignment. The polar
Alignment scope allows you to accurately align the mount to the
celestial pole at 3 arc minutes or less.
