Sky-Watcher SynScan V4 Hand Controller - Manual (Page 11)

11
At the beginning of the alignment process, users are asked to choose an alignment method.
The available alignment methods differ between the mount types, as listed below:
• For an equatorial mount:
1-Start Alignment (1-Star Align.) , 2-Star Alignment (2-Star
Align.) or 3-Star Alignment (3-Star Align.)
• For an alt-azimuth mount: Brightest Star Alignment (Brightest Star) or 2-Star Alignment
(2-Star Align.)
Note: For a detailed description and comparison of each alignment method, please refer to
Section 3.7 .
Operation:
• The LCD screen displays “
Alignment: ” in the first line.
• Use the two scrolling keys to select an alignment method in the second line of the LCD
screen.
• Press ENTER to confirm selection and proceed to the next step (Section 3.2) .
• Press ESC to skip the alignment process and enter standby mode.
3.1 Choosing an Alignment Method
PART III : ALIGNMENT
In this step, user will be asked to choose one or multiple alignment stars from a list provided
by the SynScan hand control, and then control the mount to center the star(s) in the FOV of
the telescope’s eyepiece. The SynScan hand control will then use the data collected in this
process to transform between the mount coordinates and the sky coordinates.
The operating steps of aligning to alignment stars may differ depending on the type of mount
used, as well as the chosen alignment method. Users should read the following section which
meets your mount and alignment method:
• Section 3.3: Alignment Method for Equatorial mounts.
• Section 3.4: Alt-azimuth mounts using the Brightest Star Alignment method.
• Section 3.5: Alt-azimuth mounts using the 2-Star Alignment method.
3.2 Aligning to Alignment Stars
3.3 Alignment Method for Equatorial Mounts
Aligning the 1 st Star:
1. The LCD screen displays “ Choose 1st Star ” in the first line. Use the scrolling keys to browse
through a list of star names and Press ENTER key to pick the one on the screen as the 1 st
alignment star. The mount will then automatically slew and point the telescope towards the
1 st alignment star in the sky.
2. After the mount stops, the hand control will display “ Use arrow buttons Ctr. to eyepiece.. ”.
Now the telescope should point rather closely to the 1 st alignment star (generally, in the
FOV of the finder scope), and the mount’s tracking function is also turned on by the hand
control to prevent the objects drift in the FOV of the telescope.
