EQ-13 Mount’s Load Capacity

The Orion EQ-13 Equatorial Mount has a load capacity of 
13 lbs. That means it can typically support a telescope tube 
and its accessories weighing up to 13 lbs. The amount of 
weight the mount can stably support will depend somewhat 
on the type of telescope, however. For instance, compact tele-
scopes such as Maksutov-Cassegrains have short tubes with-
out much “lever arm,” so they are quite stable on the mount. 
Longer telescopes, such as some refractors and Newtonian 
reflectors have more of a lever arm and thus may wiggle or 
vibrate for longer when touched.
