Sounds more and more like CEM means "Chinese Equatorial Mount" - Neither German nor English.



Agree with Dvb, neither German nor English. GEM is modified from an English cross axis mount with an RA axis supported on only one end. Unfortunately, GEM becomes imbalanced at low altitude setting. English cross axis mount has to be fixed on a rack with no adjustability on the altitude unless a different rack is used. It is not portable. That’s why you cannot find one nowadays even in museum. The CEM60 retains the advantage and gets rid of the disadvantage of the two. A Chinese Equatorial Mount is good, which matches its name CEM anyway.

I guess I am not understanding how the thing works because it looks like the entire DEC housing/wheel and everything would hit the body of the mount itself.
You're right tho, the black box would hit first.
I will wait to see one in action:)

Andy





this is really interesting. now I defintely want to see it in action.

I was at the ASAE and this mount caught my attention if only at first because of the strange looking design. I'm not in the market as I own an MX, but found the mount intriguing enough to ask a bunch of questions mainly about the encoders. I specifically asked how iOptron could afford to offer a mount with encoders for $4k and was told that it was because they have designed and will manufacture their own encoders. I did not read that statement in any other post here so make of it what you will.

I've been bugging mr. iotron [@5:27] for the last 2years about those encoders. when were they going to come out with them since the 45gt was way too much. even ES tdm seams too much.

I'm glad they finally came out with one. and if you here mr. ioptron the iEq30 will have that encoder also.

CEM= Chinese Equatorial Mount? This mount looks amazing. It sure looks like the bigger version of the ZEQ25.




Shhh....! It's officially a 'Center balanced Equatorial Mount'. But we can read between the lines?

Hi,

For people's reference, they do call it "Chinese" EQ mount in China.
For example, this is a forum post by a user called "iOptron:"

http://bbs.astron.ac.cn/thread-94885-1-1.html

You can see how they call it using google translate. They even also
call the ZEQ "Chinese EQ mount."

To me, it is totally OK if they just call it "Chinese" EQ mount, since this
style of EQ mount is indeed developed by Chinese people. They did not
choose to do so in their English version of advertisements, however.
I think they should be more confident about (and proud of) what they do
in front of the rest of the world.

Cheers,
Wei-Hao

Thanks for the link! It would seem the mount will track up to 15° (1Hr) pass meridian, and it's programmable (point #28)

Being a resident of a hot dusty country with weather varying between hot and dry, hot and humid, and mild winters with varying levels of humidity, I sent an email to iOpteron to enquire about the conditions in which their mounts are tested at as well as how they handle repairs and parts replacement for people who lived too far to be able to ship things back for repair. I was very pleased with what they responded with.

1) They test their mounts from -20 to +45 degrees C. Which is a very reasonable range for equipment testing.
2) When asked about dust resistance they responded that all electronics and mechanical components are enclosed (they did not mentioned sealed, but enclosed is way more than what you get with a Losmandy G11)
3) They do ship parts to customers before they receive the defective parts so as to reduce downtime (there are some reasonable conditions attached to this such as them not sending you any further parts till they receive the ones you were supposed to have sent back earlier)
4) When asked about imaging load, they responded with "The rule of thumb is 1/2-2/3 of the visual payload." So I would assume that to be safe I would not stick more than 30 pounds of imaging gear on this mount.

Sounds good so far. I never owned any of their products so I can't vouch for them in any way, but I liked the responsiveness of their customer support and I liked their policies.

I have had warranty work before and I can vouch for this that they do ship out the parts and they do ship quickly. Support has been good to work with either when I had warranty work or in doing the hand controller and RA gear upgrades.

In my experience with the iEQ45 I think the rule of thumb is okay but also dependent upon the focal length and physical length of the tube. You could probably use more weight with a short wide-field tubes than with a much longer focal length OTA. However, I bet with this one you could push the rule a litter further.

Cheers!

iOptron has just added the CEM60 to it's website. It's available to pre-order on the page, but no price point has been entered yet.

http://www.ioptron.com/index.cfm?select=productdetails&phid=35c6c70c-22f0...

The demand for this mount seems to be substantial, this is the first time I've seen a waiting list, first come, first served for an iOptron mount?

Clear skies...Paul

Yes we are, but we haven't given them a credit card number yet.

We do have a price range so not going in totally blind. It probably serves several purposes including helping them plan the initial run.

Cheers!

Just got on the list. Did anyone hear about a 120 lbs version of the mount that is to be previewed at NEAF? I was told about it when I spoke to the iOptron folks at ASAE.

Yes, that's the next release. So if you really need a mount that weighs about 55 pounds, with a 110 or 120 pound payload, then you'd better wait a bit...:)

I think I got on the list almost as soon as one could make the request - the fancy encoder version.

Now will the initial run take 12 months?

As for price - if you have to ask, you can't afford it.
