PART I: INTRODUCTION
1.
Full Feature Mode:
The flow chart of the “Full Feature” operation is shown in
Fig. 1.4a.
• The left and right keys are used to control the movements of the Right Ascension (R.A.)
axis (for an equatorial mount) or the azimuth axis (for an Alt-azimuth mount).
• The up and down keys are used to control the movements of the Declination (Dec.) axis
(for an equatorial mount) or altitude axis (for an Alt-azimuth mount).
• In most cases, pressing the “
RATE/2
” key will invoke the operation of choosing a slewing
speed:
»
The LCD screen will display “
Set Speed
”, followed by the current speed as “
Rate = *x
”’.
»
Press a number between “
0
” and “
9
” to select a new speed.
»
Press the
ENTER
key to return to the previous display.
»
If the user does not press the
ENTER
button, he/she can continue to change the speed
while using the direction keys to slew the mount.
»
If there is no keypad operation in 5 seconds, the most recent speed will be kept and
the LCD display will return to the previous ones.
• The following table lists the available speeds:
• Rate 7/8/9 is primarily used to quickly slew a mount.
• Rate 5/6 is primarily used to move a target in the field of view of a finder scope.
• Rate 2/3/4 is primarily used to move a target in the field of view of an eyepiece.
• Rate 0/1 is used to move a target in the field of view in high magnification observations,
or manual-guiding.
Note:
*1:
Speed is represented as multiples of the Earth’s rotation speed.
*2, *3: For Equatorial mounts, the speed is the drift speed of an object in FOV while the mount’s
tracking is turned on; it is not the axis’s rotation speed.
*4:
Maximum speed varies on mounts. For most Sky-Watcher mounts, it is higher than 800X
(3.4 degrees/sec).
