New Celestron CGEM DX- 50lb capacity!
      #4297927 - 01/07/11 08:57 AM

For $1999.

Got a better link. So it's a CGEM with a beefier tripod?

Looks very much like a current cgem but with a longer counterweight bar and a better tripod and spreader. I could be wrong, but Celestron's site lists the weight of the mount as being 18.6KG for both mounts.

So no magic here, but slight tweaks to the existing product ala an NEQ6 vs EQ6.

Celestron's product page

Cheers,
Chris

Now it's getting too close to the price of a Losmandy G11 Gemini II though...

A Losmandy with Gemini Goto is like 3200 bucks isnt it and is rated for 60 pounds.

If you only want an SLT...A GLT Go/To will cost an additional $1000+.

Looks like a $600 tripod "upgrade".
For 600 beans, I'd just buy a used Meade GFT.
I don't think a bigger tripod will increase the CGEM capacity 10 lbs.

That looks right on the button to me, a $600 tripod upgrade.

And a longer looking counterweight bar, we mustn't overlook that.

Looks like they added a hub to the base to mount on the larger tripod.

If anything, the larger tripod looks like a better match for the CGEM head than the CG-5 legs. I imagine Celestron will offer that tripod separately for those who want to upgrade their CGEM tripod.

Well then, there you have it. There's roughly $50 in raw costs added to the mount so there's your $600 delta between the CGEM and CGEM DX.

Perfectly justifiable right?

I guess they found they've created a hole where the the CGE used to sit and need to add a middle tier. There's no way to downgrade the capacity of the CGE PRO I guess. It's too bad the CGE is no more. I was finally going to be able to convince the CFO I could afford to buy one. Now I either have to sit tight, try the used market or continue to save for a much larger jump up.

Alas.

Well I for one am lost on the new Celestron offerings.

First we have that SkyProdigy series with a 70mm refractor for 699, a 90mm mak for 749 and a 130mm newt for 799. What scares me with these offerings is that these are the same scopes they offer on the SLT mount, so do we have an SLT mount with a better computer?

Now we have what looks to be a GCEM with a better tripod and longer counterweight bar with a claim of 50 lbs capacity? Does that mean I can toss 25-30 lbs of equipment on this for imaging? It looks like the same mount? Does that mean I could replace the CW bar and tripod on my CG-5 and get a 45 lbs capacity? I have to think that would be ridiculous thinking right?

Am I the only one scratching my head at this?

I don't own a CGEM but I've seen several threads addressing its problems. Do you suppose Celestron has worked out the kinks with the deluxe?

Scratching your head perhaps. I think the rest of us are shaking our heads.

As for working out the kinks in the CGEM, my money is on no. These might ship with the latest firmware, but I doubt there's anything craftsmanship wise that's been improved upon.

I would have purchased it, I wonder if they are just selling the tripod?

It is if the current tripod isn't capable of dampening vibrations at the heavier weights. Assuming the existing bearings and motors can handle the increased weight the other components needed to handle a weight increase are the tripod and the counterweights.

A tripod upgrade is the number one method of increasing a mount's carrying capacity. Adding weight to an existing tripod helps dampen vibrations, increasing leg diameters and the overall robustness makes a marked improvement in a mount's capacity.

The CG-5 and CGEM/Atlas/EQ-6 have very similar (35 vs. 40lbs) weight carrying capabilities while they have very different bearings and motors, the common element between them is the tripod. The CG-5 went from 25-30lb carrying capacity to 30-35lbs with primarily a tripod upgrade (the 2" steel leg version).

It's very common for folks with pier mounted configurations (the ultimate "tripod" upgrade) to report that they are very happy with a particular mount's carrying capabilities when loaded at or exceeding the rated capacities.

This new CGEM DX appears to be using a revised CGE tripod (same leg diameters, same leg clamps, same spreader bar) to provide part of the increased capabilities. Seems like an easy and smart move on Celestron's part to offer another mount to help fill the gap left by the CGE.

The question for Celestron is if this revised mount is indeed capable of carrying 50lbs of equipment on a regular basis. If there are any weak points in the existing CGEM mount's capabilities the DX will certainly highlight them.

Personally, I don't think the Big "C" cares...just throw it out there and see what sticks!

The CGEM is certainly capable of imaging with more than 25lbs of weight. The below image of M57 won't win any awards but it was taken with a 9.25 (no focal reducer so imaging at 2300MM Focal length) an 80 MM EON Guide scope and cameras attached. The weight was over 30LBS and only 1 image wasn't usable. This was also taken in a white zone with the full moon out.

Hmmm, it's easy to feel that way at times!
