Looks like there is a new mount one the market to compete with the EQ8.


Discussion on Cloudy Nights:


Who are the iOptron dealers in OZ?

The Astroshop in Brisbane retails iOptron i believe. That is a USD price i assume. So allow $5250 AUD on conversion, plus $525 GST, plus shipping charges. Probably min $6000 to your door. Its observatory only. Specs are very similiar to rhe EQ8.

The EQ8 is listed by Andrews at $5899, and that includes the field tripod/pier. You can buy the head unit alone and in the past Andrews has knocked about $700 off if you just want the head for an observatory.
Andrews has a 10% off sale on them a couple of times a year, if you can wait for that. So you might get a new EQ8 head unit for less than $5k.

If you can live with a little less capacity (34kg), the CGX-L might be cost effective, at $5399 from Bintel. Observatory or field use and comes with a good strong tripod, and plenty of advanced features. The CGX series had some early factory setup issues but that is all fixed now.

That's an impressive array of on-mount ports!

That's all well and good - but is the iOptron a better mount? and does it overcome the Dec backlash issues of the EQ8.

It will be interesting to see when people start to review this mount.

Yes it looks very nice. However i remain cautious about internal cabling feeds for cameras, power etc to the top, as any issue requires return of the whole head unit to fix. If your running external cables, a problem can be a 2 minute fix. It basically increases complexity. But that's just my opinion, it looks great.

Looks interesting, but my back of the envelope cost calculation puts it at around $AUD 7000.00. itís a big puppy, so shipping wont be cheap, and GST is levied on both the item and shiping, plus customs entry fees have gone up.

I think one of the very interesting thing about this mount will be the optional high resolution encoders.



At $5,500USD still like half the cost of an AP mount although not 100% sure that's apples for apples.

This looks like a beefed up version of their CEM 60 mount, which also had the high resolution encoder version as well as a "normal" version.
It performed well from what I can gather on CN forums, but didn't have much uptake in Aust (as least that's my limited understanding).

Yes and no
There was a lot of unexplained drift originally, as well as about a 2arcsec pk-pk sinusoidal SDE ( Sub Divisional Error). I believe the drift was fixed but not the SDE. For people wanting to image at a low arcsec per pixel, this may be something to check out, as the SDE couldnt be guided out due to the fact it only had about a 5.4 clock second period

From the CN thread, attributed as coming from iOptron:

"Currently we don't have a support for the CEM120. The Mount with 2 counterweights weighs aprox 122lbs. Add the weight of the instrument and I would say a pier that can support 250-300lbs would be optimal. Our current Tri-Pier can carry up to 220lbs so technically it can be used with thCEM120 and instrument that stay under that weight. Itís likely we will make a Tri-pier adapter plate soon. Thie image has the hole spacing for the mount base."

So if true, iOptron is selling a mount head without any offered support structure.
Obviously this is not seen as a portable or field mount. At least the EQ8 can be used in the field by a fit individual with the room to transport it.
