The CEM120, CEM120EC, and CEM120EC2 normally include two 22 lb (10 kg) counterweights.

If the two included counterweights can balance the RA axis with usable adjustment remaining on the shaft, you do not need another one. If the weights are near the end of the shaft and the telescope side is still heavy, add another counterweight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it fit the CEM120EC and CEM120EC2?\u003c\/strong\u003e\u003cbr\u003e\nYes.

They do not increase iOptron's published 115 lb (52 kg) telescope payload rating.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShould I deliberately balance the CEM120 east-heavy for imaging?\u003c\/strong\u003e\u003cbr\u003e\niOptron's current CEM120 instructions call for balancing both RA and DEC rather than specifying an east-heavy bias. We recommend following the mount's current balancing procedure and adjusting the counterweights until the RA axis is properly balanced.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this below 10° latitude?\u003c\/strong\u003e\u003cbr\u003e\niOptron specifies a special low-latitude counterweight, #7326LL, for CEM120 installations below approximately 10° latitude. If you are installing the mount that close to the equator, use the low-latitude version specified by iOptron rather than assuming the standard #7326 is the correct configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this fit another manufacturer's mount with a 1.5\" shaft?\u003c\/strong\u003e\u003cbr\u003e\nThe #7326 is made specifically for the CEM120 family. Even if another mount has a similar shaft diameter, check the manufacturer's counterweight requirements, shaft dimensions, and locking arrangement before attempting to use it on a different mount.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe #7326 is a simple accessory with a simple job. If the two counterweights included with your CEM120 balance the finished telescope comfortably, you do not need another one.\u003c\/p\u003e\n\n\u003cp\u003eIf a heavier imaging system has pushed those weights toward the end of the shaft, adding another 22 lb counterweight gives you more balancing range and lets the weights sit closer to the RA axis.
