About this product

Model:  iop_cem60_7200
Part Number:  7200

Now with higher payload! 

The new updated CEM60 features an increased payload of 27kg / 60lbs! *

The mount's centre-balanced equatorial mount (CEM) puts the weight of the payload at the centre of gravity for greater natural stability. This enables the mount to be surprisingly light, compared to its payload. Polar aligning is also quick and accessible because the polar scope is not blocked by the declination shaft.

The CEM60 is equipped with the iOptron's most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 200,000 objects.

Other features include an adjustable counterweight bar, magnetically loaded gear system, gear switches on both R.A. and DEC axes, screw/worm type latitude adjuster and integral cable management system. 

Note 1: If you buy the mount with an iPolar we will install it free of charge smiley

Note 2: Tripod/Pier not included.

Hard Case

The Hard Case for the CEM60 mount protects your mount whether you're heading out for a night of observation, or when you need to store it. The case features custom-fit foam padding to hold the mount in place and cushion it from impacts. The exterior has reinforced edges on the outside to help minimize denting and damage. There are dual trigger latches to secure the lid in place, and a carry handle.

Fantastic Upgrade
Friday, 29 May 2020  | 

I absolutely love this mount, It was an upgrade for my AVX which was just not cutting it with an Edge HD 8" SCT on top and others bits and bobs (about 11kg payload) for Astro Photography. If you want to get into AP then save your cash for a mount such as this. Its features are fantastic, everything from the hand controller (which I barely use as all automated) to the built in GPS and bubble level, saddle power sockets... its quiet and smooth, balances beautifully and handles tons of weight (unlike the AVX!). First week using it, I am now guiding at an average RMS of 0.5, Yes I said 0.5 !!!!! 5 minute exposures and not even a hint of star trails... I love it!
I didn't bother with the EC version for 1k more - good guiding software is all you need (PHD!).
Its getting used every night at then moment, stay away clouds, this is too much fun!

Amazing customer service and amazing mount!
Thursday, 23 January 2020  | 

FLO has fast and awesome customer service! First night out with this mount was amazing; out of the box it was guiding straight 4 hours and 30 minutes on average 0.74 RMS without massive tweaking of default PHD2 parameters. Every single subframe was perfect! Total or 49 x 5 minutes of data! This mount is amazing!
