iOptron CEM60 Equatorial Mount

iOptron continues to improve their equatorial mounts and the CEM60 is no exception to this rule.  Capable of carrying a payload of 60 pounds the CEM 60 is also comparatively lightweight at only 27 pounds for the mount head.   By balancing the payload over the center of gravity, iOptron has created an equatorial mount that has one of the best weight to payload ratios.  In addition to it's trim weight, other features include an adjustable counterweight bar to prevent obstruction with the tripod or pier. Plus polar aligning is quick and always accessible because the polar scope is not blocked by the declination shaft.

The iOptron CEM60 EQ is equipped with GOTONOVA® GOTO advanced technology, and is one of the most robust and precise GOTO mounts on the market. The Go2Nova® Hand Controller is exceptionally user friendly to use and holds a database of over 300,000 objects.

A good step up but still some 20th century feature
I've had this mount for about a month and have been extremely pleased with it. I'm using it with a Tele Vue 127 but it could certainly take a larger load. I have been using an old Losmandy G11 Gemini 1 for my travel mount. Though the G11 will probably carry a bit more weight than the CEM60, it falls behind in convenience.

CEM60 PROs: Easy to set up. Nice carrying case comes with mount. The magnetic clutch system is innovative and effective, though a little hard to get used to. Built-in GPS and polar scope are easy to use and very helpful. The mount tracks quite well unguided, compensates for PE easily, but tracks beautifully with an SBIG ST-i. The mount is essentially silent! No more screeching gears in the night. Solid and stable, well designed and built.

CEM60 CONs: Both the hand control and the mount needed firmware updates and these were more than a bit tricky due to the poor description of the update procedure in the manual. Also, the manual doesn't describe the clutch engage/disengage system very well, and major damage could result if the operator doesn't understand this system from the very first minute of setting it up. Once you know how to handle the clutches, though, all goes well. The built-in USB hub is a nice idea, but it lacks an internal 5V power supply, so you can only use it with a powered USB port on your laptop. This defeats the stated goal of minimzing the number of cables that run from the mount to the computer. Very disappointingly, the output signals from the mount tracking board are plain old RS-232 serial, circa 1980, so you have to buy an RS-232-to-USB converter to connect the mount to a laptop (really now, iOptron, you could have invested $5 to include a simple 5V power supply and another $5 to include a serial-to-USB converter circuit in the control board for a $2500 mount!).

Despite the quibbles which are readily solved, I am ecstatic about the PROs of the mount and highly recommend it to others! See photos from Joshua Tree National Park taken over the Presidents' Day holiday.

Impressive Performance (so far)
OK, this is a relatively new product. The instructions (on-line only) have the flavor of beta tester - A few details are missing that would have made set-up easier. Up-close, the mount shows mold-marks and flaws that some other brands would not show (but consider bang-for-the-buck). Also, points off for a missing counterweight screw, but points added for quick response by the IOptron people to replace it.
First night out was mostly familiarization, so alignment was a bit sloppy since I was trying to figure out the operation of the mount with a 5" apo refractor. So, with sloppy alignment and all, I was absolutely shocked when a one-star alignment resulted in the first go-to object appearing in the main scope's low power eyepiece just off center. Second object, same off-center position and distance. Meridian flip, same location and distance just off-center! Another object, same story!! So, go-to performance seems to be scary good. Bonus - No coffee-grinder here: The mount makes a pleasant, soft, mechanical whine at full slewing speed. That's really nice and it won't alarm the neighbors. More to come - I really bought this mount for imaging, and early impressions are that it should do very well.

Feature reach GO-TO mount!
I purchased the CEM60 mount about two months ago to replace a smaller go-To mount to be used on “dark skies” imaging trips. Shortly after I received the mount from OTP I unpack the mount and assembled it to get familiar with it prior to an imaging trip.
• CEM60 is well constructed and fairly easy to assemble
• Assembly and operating instruction were fairly clear and only available on-line (at –not a big problem if you have internet access and are not in a remote “dark skies” location
• The first set-up time was less than 20 minutes and was aided by viewing available YouTube videos in advance of receiving the mount. Subsequent setups were much faster
Small Issues:
• As received from OTP the mount was several months behind in firmware updates. Not a big surprise for a new product
• The latest On-line firmware updates were available for download at but required a bit of study and trial and error to complete.
• Again, studying iOptron instructions and the available on-line (blogs, groups, etc.) info helped to get the updates loaded fairly quickly.
First-Light visual observations at my dark-sky location confirmed that the iOptron CEM60 was a very good choice for me. The included polar scope and embedded polar alignment application helped greatly to provide me with several nights of impressive go-to performance. My next step is to evaluate the CEM60’s performance during astrophotography sessions in the field.
Clear Skies,

Questions & Answers

Product Questions

What is the diameter of the counter-weight bar?
Does this mount have lunar, side real and solar tracking rates?
With the CEM60 will I need bar extension or additional weight to properly balance a C11 (c. 32 lbs. as equipped)?
Specifications state no power supply, 12v battery required. Included Items states AC Adapter included. So does the mount have a power supply or not?
Will it fit onto ZEQ25 tripod?
Does this mount work in the southern hemisphere?
Is this mount capable of tracking past the meridian? If so, how far past the meridian
What kind of dovetail rail does it support ? Losmandy ?Vixen style ?
Mount capacity is listed at 60 lbs. Is this total of OTA + counterweights? How is this number figured?
Does this come with a tripod or pier? Is a carrying case available for this mount like the 45?
