Balancing the Telescope

In order for the telescope to be stable on the tripod and also for it to move smoothly, it must be properly balanced in both vertical and horizontal axes. The horizontal axis is commonly referred to as the DEC (Declination) axis and vertical axis the RA (Right Ascension) axis. Most

of the motion of the telescope takes place by moving about these two axes, separately or simultaneously. Become familiar with how the telescope moves on each axis and their corresponding locks.

Fig 26: Balancing the OTA

Declination Balance: This is achieved by moving the telescope optical tube fore and aft within its holder, so that the weight is equally balanced along the DEC axis.

•Schmidt-Cassegrain (SC) OTAs: Carefully unloosen the DEC lock (see Fig 25), keeping one hand on the OTA to control its movement. You will notice that the OTA will want to rotate in one direction. Carefully loosen the two dovetail lock knobs just enough, so that

the OTA can be slid fore and aft. Slide the OTA until it no longer rotates in either direction and is balanced. When the OTA is balanced, tighten the two dovetail lock knobs firmly.

•APOS and Coronado SolarMaxII OTAs: Carefully unloosen the DEC lock (see Fig 25), keeping one hand on the OTA to control its movement. You will notice that the OTA will want to rotate in one direction. Carefully loosen the two cradle lock knobs (see Fig 26) just enough, so that the OTA can be slid fore and aft in the cradle. Slide the OTA until it no longer rotates in either direction and is balanced. When OTA is balanced, tighten the two cradle lock knobs.

RA (Right Ascension) Balance:

At this point you will need to use the LX80 hex tool (Page 12, Fig 9, 31). This tool can be found at the lower left of the backside of the drive base. Twist counter clockwise to remove the tool from the mount. This tool contains a hex head wrench that fits multiple fasteners and adjustments on the mount.

Tilt the Mount head: Use the dedicated LX80 tool to tilt the mount head about 45° from the standard alt-az shipping configuration (reference the scale cast into the base, Fig 29). Note that for this balancing exercise it is not necessary to precisely tilt the head to 45°) — an approximation is all that is required.

Loosen the right and left side latitude lock (Fig. 28) using the LX80 hex tool. Then insert the tool into hex headed latitude adjustment. Twisting counter clockwise will begin to tilt the head towards 45°.

Release the RA Lock: Unlock the RA lock by moving the lock knob left (counter clockwise), keeping a hand on the counterweight shaft to control rotation. The mount head will now have tendency to rotate in one direction
