AUTOGUIDING
The Nexstar 6SE and 8SE include a port labelled "AutoGuide" next to the AUX port on the base of the fork arm This is an
advanced feature only intended for long-exposure astrophotography with the optional EQ wedge The previous steps for
wedge alignment should be completed before connecting and using an autoguider camera
1 You will need a suitable autoguiding camera with a 6 pin ST-4 "phone jack" cable
2 This camera will need to attach to the rear of the telescope with an optional off-axis guider or to a small optional guide scope
attached via a dovetail rail to either side of the OTA
3 Adjust the slew limits to prevent these accessories from hitting the fork arm or base during operation
WARNING: This port is not wired the same as an AUX port. Plugging in accessories such as the SkyPortal WiFi Module,
SkySync GPS, or others into this port risks damaging the accessory and the telescope's internal electronics.
Never plug anything except a 6 pin ST4-style auto guider cable into this port.
FINDING THE CELESTIAL NORTH POLE
In each hemisphere, there is a point in the sky around which all the other stars appear to rotate These points are called the
celestial poles and are named for the hemisphere in which they reside For example, in the northern hemisphere all stars
move around the north celestial pole When the telescope's polar axis is pointed at the celestial pole, it is parallel to the
Earth's rotational axis
Many methods of polar alignment require that you know how to find the celestial pole by identifying stars in the area For
those in the northern hemisphere, finding the celestial pole is not difficult Fortunately, we have a naked eye star less than a
degree away This star, Polaris, is the end star in the handle of the Little Dipper
