Useful Tips For All Observations; Removing The Finder Scope; Using The Indexed Scale; Rotating The Focuser - SKY-WATCHER ESPRIT 80 ED Super APO Instruction Manual

Useful tips for all observations

During an observation, when the desired target is acquired, it
is possible to remove the finder scope from its support. When
needed the finder scope can be inserted again.
This can be useful when the observer's head is in a position
where the finder scope becomes an obstacle to observation.
The indexed scale on the focuser drawtube gives an accurate
indication on the focus position for various accessories.
Once the position for one accessory is known it is very easy to
approximate the focus position.
Due to the precision needed to reach perfect focus a fine
tuning is advised.
The whole focuser body can be rotated. It is useful when the
focuser knobs aren't in a convenient position.
1. Remove all accessories from the focuser.
2. Fully retract the drawtube inside the focuser body.
3. Unscrew the "boat wheel" like large aluminum ring.
4. Rotate the focuser body.
5. Tight back the "boat wheel" like large aluminum ring.
