"We've been waiting for a sub 30lb mount with about 60lb maximum carrying capacity for some time now. The iOptron CEM60 fits into an ideal position in the market, where the portability vs. carrying capacity ratio allows for either observatory or field use with larger telescopes or dual-mounted refractor/reflector combos. The CEM60 is a pleasure to use, with almost zero backlash evident during autoguiding corrections and slewing. It slews and tracks very smoothly and quietly, so it won't wake up the neighbours. The CEM60 "standard" model is routinely autoguided down to a very low periodic error by experienced customers with a rigid optical tube. In fact, many customers have commented this is the best mount they've owned to date, and a significant upgrade to their previous mounts. The more expensive CEM60-EC with it's Realtime Periodic Error Correction or "RPEC", has been shown by customers to be capable of sub arc second periodic error with auto-guiding and a good quality rigid optical tube. Until now mounts offering this level of performance have cost a lot more. Stay tuned as more images appear from satisfied customers. This is truly a revolutionary product, and has changed the market and customer's expectations at this price-point. "  - Altair Astro Staff

Below are two images taken in London in 2014 with the RC250-TT and iOptron CEM60 mount by customer Jaspal Chadha. The left image is taken using narrowband filters (Ha 5x1200sec, SII 1x1800sec, OII 2x1200sec) and the right-hand image is taken using RGB filters (Red 3x600sec, Green 3x600sec, Blue 1x600sec, Ha 4x600sec) :

Two versions of the CEM60 are available. The CEM60 which is the "Standard" model with Programmable Periodic Error Correction (PPEC) and the CEM60 "Advanced" model with optional Real-Time PEC for incredibly high tracking accuracy, intended for customers with longer focal length instruments, or those who want the very best tracking performance available. Either mount still offers simply amazing performance in it's class.

The iOptron CEM60 mount features a large dual 1.75" / 3" dovetail clamp for convenient use of most telescopes on the market. Other features include an adjustable counterweight bar to prevent obstruction with the tripod or pier. Polar alignment is quick and easy with the AccuAligning^TM polar scope, which can be viewed-through regardless of where the mount is pointing, because it isn't blocked by the declination shaft.

Another feature is through-cabling to reduce the number of cables around your telescope and imaging accessories. 2x 12v power-out ports and 4x USB ports are conveniently placed just below the dovetail clamp on the mount's RA axis.

For the ultimate in stability, consider the ultra-stable Altair Starbase Field Pier / Tripod, which sets a new standard for freedom from flex, strength and stability. For permanent mounting, consider the Altair/SkyShed 8" Steel Observatory Pier, with a unique design, making it the easiest-to-install pier on the market. (See thumbnail images and ordering options).
