Revision 2.0
If this fails, completely remove the homing sensor housing and use an alcohol soaked
cotton swab to clean between the posts marked by the red arrow in Figure 10.
Right Ascension Axis Sensor Replacement
The procedure for accessing and removing the right ascension homing sensor is similar to
removing the declination sensor. Please carefully review “Removing the Declination
Sensor” before proceeding.
The right ascension axis homing sensor sits behind the right ascension gear and must be
accessed by removing one or both of the right ascension housing side panels.
This first step is to rotate the right ascension axis balance knob to separate the worm from
the gear so that the mount swings freely. As always, use appropriate caution.
Next, see “Removing the RA and Dec Side Panels” in the Paramount ME User Guide:
http://www.bisque.com/sc/media/p/28169.aspx
for details how to remove the side panel.
If you wish to check the integrity of homing sensor cables or want to try cleaning out the
right ascension axis’ optical sensor with compressed air while troubleshooting homing
failures (see “Cleaning the Optical Sensor”), first remove the panel on the RA housing
box referenced in Figure 35 of the Paramount ME User Guide (this is the panel on the
right side of the mount when looking at the Adaptor Panel).
Figure 11: Right ascension housing with the right panel removed. Follow the orange and yellow
cable to locate the homing sensor.
