Speaking of Meade and the EQ8, an Australian owner (Jonathon, on the iceinspace forum) just posted this video to You Tube demonstrating the grippiness of the clutches and the excellent damping of his EQ8 with 14" Meade LX200. (2,200mm fl.)

Good video.

I would still like to know more about those encoders.

If this baby delivers with guiding it will be a top product. The discussion about the encoders is correct; they have 1.2 arcmin of resolution and the rest of the accuracy comes from just counting stepper motor steps.

The payload and the price sets it in a class by itself, me thinks. It will be very interesting to see the AP performance!

Oh dear - I though I could buy one & get Renishaw encoders
just like an ASA mount for 1/4 of the cost.

I was only dreaming.

EQ8 mounts have arrived in New Zealand, just need to set up on permanent pier and test.

Rob, I see that you've got the 2 counterweights right down to the bottom. Are they enough to balance your 12"? Looks like 3 or 4 weights will be needed depending on the users setup.

Don't think so.
I am surprised that no one else has noticed this.




There's a reason for it: There's no way this will be the result of a non-orthogonal mount. It's your set up. Check that everything on your mount (like the tripod to head attachment) is secure. Make sure the latitude adjustment bolts are locked down. Check that the telescope or its mirror are not moving. Check that you are not moving or bumping the polar axis at some time.

I have checked all that.
I have always noticed this problem.

Well, sorry about that. You might have an experienced amateur from your local club have a look at your mount.

Yup. Polar alignment is polar alignment. The RA axis doesn't know or care where the telescope is pointed - and isn't affected by moving the telescope unless something is wrong. If you get drift after moving the telescope then either the polar alignment is worse than you think or the RA axis is physically shifting due to some mechanical problem.

Am closely following all the EQ8 threads and results with great interest.

I was (still am ) desperately saving for a Mesu 200 as after doing lots of research here in the UK it seems the best reviewed (Olly Penrice's reviews of Yves's and Steve Richards review in Sky at night mag) and best bang for buck feature for feature.

However with weights and saddle it comes to £5274 which is well over twice the price of the EQ8 at £2465 without tripod.

Out of the 2 I prefer the friction drive and higher capacity of the Mesu 200 but am coming to the conclusion that the EQ8 will easily match my requirements and save me £2809!...that would get me a nice new refractor to put on it

Due date in the UK seems to Sept/Oct?

Tom

Must be getting blind in my old age...I can't find the price.

I assume you haven't priced mounts with similar payload capacity recently.

The blindness must be contagious! I can't any reference to the price either!

We won't know its U.S. $ price till it goes on sale here. That will depend somewhat on who the seller is. Given the overseas prices I've seen, I expect it will be in the 4K neighborhood. Less than the CGE Pro and Losmandy Titan, apparently, anyway.

Well now, I don't feel so bad. I am really anxious to see how it stacks up against the CGE-Pro. Great thread folks!

I'd be a little concerned that they (Mesu) have discontinued the Mesu 1 mount.. might support be a problem? I was investigating one.. not anymore

*clicks on link and watches video*

Wut? Some folks are totally spoiled. Come to Denmark, and I'll show you some horrible seeing.

But I am totally impressed by the new mount. It should be a blast for those folks with big refractors.


Clear skies!

Since I'm not really observer, I'll be impressed with this mount when easy and problem free long sub guiding is evident from multiple items.
