In the “Mount Setting” menu, choose “Backlash Compensation” with the or direction key
and press the key to call up the dialog box.
In the “Backlash Compensation” dialog box, move the cursor to entry spaces with the or
direction key and enter your desired values with the or direction key. Pressing the
key will shift the cursor to OK. Then press the again to save and leave the dialog box.
Setting the Backlash
The values for the backlash compensation are available between “0” and “99” both in R.A and DEC.
Setting the Backlash
Watch how the telescope moves when you increase the value. Start with setting an initial reference value (10 for example), and double this
value after checking the telescope movement with the initial value.
If the second value (=20) is too small to compensate for the backlash, enter the number doubled (=40) as the second value. Likewise,
increase the number by doubling the value if necessary.
Example: Enter 20 for setting the backlash compensation.
If this value is too weak for the compensation, increase the value to 40. If it generates too much compensation as a result, decrease to the
value halfway between 20 and 40. If the value of 30 is still somewhat larger for the compensation, decrease to 25. On the contrary, if 30 is
somewhat small, increase to 35. In this way you can adjust the mount for the most effective backlash compensation.
Example: R.A = 10, DEC = 25
Note: Using the or zoom key will increase or decrease by 10 within the range.
Note: Tne “Backlash Compensation” has to be null if you use an autoguider.
R.A = 0, DEC = 0
