CGEM-DX... any thoughts?
      #4403678 - 02/22/11 12:13 PM

It appears that Celestron has announced an upgraded CGEM-DX mount to fill the gap between CGEM and CGE Pro.

Looks like the only real difference is a larger tripod, "beefier motors" (no idea how much beefier) and a thicker counterweight shaft. With this they've rated it at 50 lbs, 10 lbs higher than the regular CGEM.

Not really sure if I really buy the extra 10 pounds being worth an extra $500 of purchase price. Although it could be rated conservatively. They do claim that it can mount the 14 and the edge 14. But I am also a bit skeptical about just how comfortably they will be mounted.

I think I'll have to wait and see how this pans out.

I saw that on their website about a month ago. The first thought that went through my head was a mount that could be used for AP with a larger 150mm refractor. But a mount like that could be used for any large 8-12" reflector or as they list up to a 14" SCT.
But will there be a time period of working out the bugs or will it work right out of the gate. That is something for us to wait and see.

Actually its a new motor driver chip, allowing more power to the motors to increase torque...not new motors.

Well.., that's the trick question, isn't it

Personally, I figure its a slick play by Celestron to provide folks with an option above the CGEM / Atlas payload at a price that is still well below that of the Losmandy G11 - by some margin, to boot.

If it can carry the C14 as well as the regular CGEM carries the C11 then it is definitely worth an extra $500 IMO.

Well.., Which C14 is it supposed to be able to carry?

The Edge-14 bare optical tube weighs 45lbs - if you swap out the dovetail for the Losmandy DC-14, you add 3.75lbs.

There's more stuff (dewshield, diagonal, eyepieces, finder, etc) to be added in order to get to a usable instrument - each of which not only adds up in literal weight, but compounded by moment arm overheads as well.

I can see the temptation, but would caution against literally ignoring the math involved.

Personally, I think it's an attempt to not lose market share to Losmandy, et. al. because they killed off the CGE. While I think the beefier tripod will provide more stability, the mount mechanics are the same and therefore the capacity is not really increased.

$600 marketing ploy.

Well.., to be fair - this isn't the first mount to get this makeover.

Remember the SkyWatcher NEQ6 mount?

"Personally, I figure its a slick play by Celestron to provide folks with an option above the CGEM / Atlas payload at a price that is still well below that of the Losmandy G11 - by some margin, to boot."

That margin is not really much considering the G11 is in a different class in precision and construction.
I've decided to keep my CGEM that came with my C11Edge scope because I can still carry it with the tripod attached.
I don't think it is doable with the DX with the beefier tripod.
I had a CGE and now I have a G11 and I think the later one is a much better mount specially with the new Gemini2 computer.

I tend to agree. Ten lbs more capacity for at least 16 lbs more scope (my 11" HD weighed in at 29.7 lbs w/dovetail). But perhaps "C" will have a 14"HD set up on a CGEM DX at NEAF for a look-see in April.

Good to know, thanks for the input!

This does seem to be the general opinion on these boards (of the quality of the Losmandy mounts) so I will definitely be considering the G11 for my next mount purchase.

OK lets put it this way then: Take a standard CGEM, install a Losmandy saddle and stick it on a concrete pier. That's basically a CGEM-DX (in fact probably sturdier). Now stick a C-14 on it. See how it wobbles. Oh, i forgot about the thicker counterweight shaft....ooh, THAT's gonna make a big difference in carrying capacity. My mistake.

No, i have not. I do, however have a C-14 on a CGE on a concrete pier. I know what that is like. If the CGEM-DX matches the stability of that setup or comes close, i'll eat my words right here, then i'll promptly go out and purchase one!

The OP asked for opinions on a yet-to-be-released mount. I gave mine. BTW, i'm currently setting up my EQ-3-DX on a 3" legged tripod so i can mount my C-9.25 to it.

Yes I did ask for opinions, I also am quite skeptical that it will be able to sturdily hold a C14. Celestron does seem pretty convinced, though, that the C14 CGEM-DX will be a hit. If I were to get one of their 'combos' it would most likely be the 11 or the edge11

On this vein, does anyone know how well a Losmandy G8 w/ Gemini would hold up under a C11? The CGEM-DX does seem to be a similar price point but the losmandy looks nicer and seems to have better reviews.

There is a new Yahoo group for the CGEM DX. In order to avoid rampant speculation with no facts to back it up (which has been a bit of an issue with this mount), the group will not become officially active until after the mount is released to the public or is otherwise made available for actual testing. However, after that time, I hope that those people who obtain the mount will join up to let us all know what they find.

The "new" non-edge C14's reportedly 53#...how is it gonna ride on a mount rated for 50# with accessories added?!?! Perhaps an older 45# C14 maybe, but not one with the heavier rear cell IMO. Linky...
