Eyepiece (6) Diagonal (5) The telescope is now fully assembled and ready to use. You can move the telescope in altitude direction (up and down) and azimuth direction (left or right) by slightly release the latitude adjustment knob (24) and azimuth adjustment knob (23).
3. Retighten the counterweight lock knob. The telescope is now balanced on the R.A. axis. 4. To balance the telescope on the Dec. axis, first tighten the R.A. lock knob (14), with the counterweight shaft (17) still in the horizontal position.
6. Position the telescope in the tube rings (10) so it remains horizontal when you carefully let go with both hands. This is the balance point for the optical tube (11) with respect to the Dec.
4. Using the Telescope With the telescope aligned on the pole, you are now ready to start your observations. 4.1. Getting familiar with you mount and telescope Before observing a celestial object, looking at terrestrial objects during the day provides a good exercise on how to operate the mount and telescope.
To calculate the magnification factor, divide the lens' focal length by that of the eyepiece. The resulting value represents the magnification factor offered by the telescope when it is used with this eyepiece. For example, using a 20 mm eyepiece provides a magnification factor of: Magnification = 900 mm/20 mm = 45X 900X70@ioptron.com...
Keep the caps on the front of the telescope and on the focuser drawtube when not in use. Your 900X70 telescope requires very little mechanical maintenance.
A. iOptron warrants your telescope, mount, or controller to be free from defects in materials and workmanship for one year. iOptron will repair or replace such product or part which, upon inspection by iOptron, is found to be defective in materials or workmanship.
