On a very cold day, there is a stall or vibrational noise while slewing and dose not properly 
move.  

-

 

If the weather is below -10 °C, it is recommended to attach counterweight or to reduce the 
maximum motor speed to about 50% level to minimize the mechanical burden to the mount 
Please contact HOBYM Observatory if you continue to experience the same problem after 
trying the above-mentioned suggestion. 

 

 

What telescopes can be mounted without counterweights? 

-

 

The Crux140Traveler has a large payload, but it is recommended to use a counterweight or to 
mount less than the recommended payload when taking photographs. Maintaining a safe 
payload will ensure the quality of photography. Please refer to 

“What is the safe payload?”

 

section of the FAQ for more details.  

-

 

The example below is the case of observing with an eyepiece. 

Takahashi: Refractors under FSQ106, Cassegrain telescopes under Mewlon-200, Epsilon-
160 

 

GSO: 8-inch RC telescope or less, 8-inch reflector or less 

 

Celestron, Meade: 8-inch Schmidt Cassegrain Telescope or less 

 

Vixen: Visac 8-inch, R200ss, 4-inch Refractor or less 

For astrophotography, use smaller telescope because extra equipment is required. 

 

 

The guide graph is poor. 

-

 

There can be two major causes.  

-

 

The first is when the polar alignment is not precisely done. If the tripods are lightweight, the 
polar alignment can be distorted after you mount the telescope to the tripod. It is 
recommended to install on a hard floor, set the telescopic cameras, etc. and then proceed to 
polar alignment. 

-

 

The second case is when the seeing is not good. 
Since the CRUX mount has no backlash, the scene has a major influence on the guide 
quality. Often, when seeing is poor, the guide graph has a high correction level and large 
peak-to-peak. 

 

 

The motor stalls while slewing. 

-

 

There can be two causes. 

-

 

The first is power issues. The problem may occur due to the low voltage because of the 
insufficient DC adapter capacity or a low battery. In this case, use a DC adapter with a higher 
capacity or charge the battery. 

-

 

The second is when the payload weight is exceeded. In this case, reduce the load to the 
mount. 
Even if the telescope is within the recommended payload, when it has a large aperture, the 
payload will be lower as it gets farther away from the DEC mounting surface. 

 

 

About the holding torque of the motor 

-

 

There may be a possibility that the mount slips when a heavy telescope is mounted, and the 
mount turns off. Therefore, it is recommended to uninstall the telescope before you turn off 
the mount. Do not forcibly rotate the axis of the mount, as it generates electrical power and 
may cause severe damage to the Titan TCS.
