So, thought I would start the review with what I've learned so far. This is Part 1 of a 2 part review. Part 2 will deal with the actual Polar Alignment and guiding performance if and when the weather ever cooperates. When my mount arrived it was in a very nice metal case. However, the Quick Start Guide was not included. The large red knob toward the upper right of the mount is the Dec gear switch.

There is an identical knob for the RA gear switch. Little decals show whether the gears are locked or unlocked. The knobs are easy to turn and don't hurt your fingers like my ZEQ25 knobs did. The Dovetail Saddle can be configured by the user to accept either a Vixen or Losmandy dovetail slide while keeping both styles centered on the mount. Mine came configured for a Vixen dovetail. Since I haven't had a chance to do any guiding bad weathernot able to comment yet on any benefits that may come from the encoders.

Do the encoders help the guided performance? Many questions but no answers yet. That will likely prove to be useful. It turns out, the cable management capabilities are even better than I had anticipated. There is an opening in the middle of the dovetail saddle see first picture below which shows three cables already inserted into the opening that allows cables to be run through the mount to either the back of the RA axle or the bottom of the Dec axle as shown by the yellow dotted lines in the second picture below.

I have two Dew Heater cables and the video cable from the guide camera routed through this opening. I have brought these cables out at the back of the RA axle so they exert virtually no torque on either the RA or Dec axes drives. This has made balancing my telescope a breeze.

The balance no longer changes as the RA axis progresses through the night. This Panel can be moved to the front of the dovetail saddle if desired. That port is pre wired to a USB connector on the back end of the RA axle just below the routed cables come out the back end of the RA axle see image below. I currently don't use this power.About My Account Newsletter Sign-up. Products Dealers Support News.

Internal iPolar eletronic polar scope.The iOptron CEM40 centre-balanced equatorial mount is an unusual design. In the CEM design, the declination axis is offset to the lower end of the RA right ascension shaft, on the opposite end to the counterweight.

With features normally found on high-end mounts, it also maintains a strong foothold in the portable grab-and-go arena. It has an impressive 18kg load capacity for comparison a Celestron C11 optical tube weighs We were also impressed with the quality of the online electronic documentation provided for this mount. It took us through the initial setup procedures in a well-organised, logical step-by-step fashion. On our first outing, our rough polar alignment was too rough and the star recognition system failed due to the pole being outside the image frame.

Although we assumed we would have to initiate another match attempt ourselves, the recognition software had kept watching and reported a match. A couple of hex bolts need loosening to do this and a magnetically clipped hex key is kept on the mount. The software zooms in on the cross and circle when alignment gets close. A channel GPS dongle is provided, supplying location, date and time information automatically. We selected numerous targets. With a camera attached to a 1,mm focal length scope, we instructed the mount to slew to each target and took an image.

The object was fairly well centred each time. We were able to set up the CEM40 in a couple of minutes with the ability for precise Go-To and excellent unguided tracking, achieving exposures at 1,mm focal length of 2, 3 and 4 minutes without noticeable star elongation. For extended exposure, the CEM40 provides an ST4-compatible guide port for autoguiding functionality.

This is where the 18kg-load capacity is important, allowing for a substantial guidescope to be fitted to the main imaging scope. Overall, we were impressed with the CEM Its excellent Go-To and tracking precision also make it an exciting prospect for astrophotography. A conventional German equatorial mount places the declination axis at one end of the RA shaft, carrying both the mass of the counterweights and scope.

In the CEM design, the declination axis is staggered so the counterweights remain at one end of the RA axis with the scope sitting at the other. This design balances the RA axis, placing its centre of gravity directly over the tripod or pier. The lack of bias to one side of the RA shaft helps improve stability.

A straightforward mechanical procedure is required to select your desired range before initial operation. The CEM40 operates via high-resolution stepper motors capable of 0. A cable management plate on the dovetail clamp offers a USB 2.

This presents a number pad, four direction arrows, menu, back and enter buttons. Accurate polar alignment is performed via an in-built iPolar electronic polarscope. A dedicated USB port is provided for connection to your computer or laptop running the iPolar software.

Once connected to the scope, the software is able to detect and identify the stars around your local celestial pole, indicating how to adjust the mount for accurate polar alignment.

A small mechanical procedure is required to set the clamp for the appropriate dovetail type. The position of a fixed block — which the clamp locks the dovetail against — can be adjusted to ensure perfect dovetail rail-centring. The CEM40 has free-running bearings.
