Imagine a mount head that weights only 27 lbs. (12.3kg) and will accept a payload of 60 lbs. (27.3 kg)!
It's a real dilemma for a lot of amateur astronomers.
They want an equatorial mount that will do the job,
but does not require them to be Arnold Schwarzanegger to lug it around.
And the mistake I would often see made, is to keep the weight down, astroimagers especially
would undergun the mount and that creates even bigger headaches, in terms of tracking and
They wanted to avoid a heavy duty (and heavyweight) equatorial mount, and I can understand that.
Up till now, this type of mount simply did not exist.
Then, the engineers at IOPTRON, who have spent the past several years and created
several types of portable mounts, put their heads together and have now addressed the problem.
Introducing the Ioptron CEM 60 mount.
Here is how it works:
The CEM 60 centre's the payload of your instrument, and the counterweight directly
over the mount's center of gravity.
As a result you have more stability.
It's that simple!

PS The price is right in line with other competitor mounts, which of course are much heavier.
