CGE Pro
      #5492918 - 10/28/12 10:50 AM

Does anyone out there have a new(er) CGE Pro mount? I've only been able to find one extensive review of this mount that is somewhat negative but is also a year old. I'm debating between buying a G11 or the CGE Pro. I currently have a CGEM that is OK but the OTA is a bit too heavy for astrophotography on that mount. I just saw a retailer selling the CGE Pro (usually ~$5K) for $4K. I have a quote for a G11 with the worm upgrade for ~$4K. So, price-wise they are on equal footing.

So, tell me which would be the better mount? With the CGE Pro all the NexRemote stuff I have for the CGEM should work with minor adjustments so it might likely be an easy transition. I have no idea how well the G11 software works.

Ideas to help the decision?

The CGE Pro is an excellent mount BUT... There is that huge, tall electronics pier. If you contemplate using this mount in portable fashion, make sure you will want to/be able to deal with it. Given the traffic on my CGE Pro Yahoogroup, it has been substantially improved (PE wise) in its latest incarnation...

$4K will buy pretty good quality and modest capacity, or modest quality and pretty good capacity. If your load requirements exceed what a G-11 can manage well then a CGE Pro makes sense. If you don't need the extra capacity then the better but smaller mount would be worthwhile. For imaging, the breakpoint is probably somewhere around 45 pounds.

Uncle Rod, I have a permanent roll-off roof observatory I just finished building. It has 6' walls so mount height is important. The higher the better - to a point. I do like the electronics pier - keeps cables away from the moving parts. G11 has a panel instead.

All: Why is G11 better than CGE Pro? What are the primary points that determine the rating you give?

Thanks!

Who said it was? The CGE Pro is more comparable to the Losmandy Titan...

Well, yes - in capacity. If you pay the higher price of the Titan, you can get the quality of the G-11 with the capacity of the CGE Pro. If you don't need the increased capacity, though, why pay for it? I'd rather move up a notch in quality if a smaller mount meets my needs.

That said, the OP hasn't been specific about load requirements. If it's 40-45 pounds then a used EM-200 can be had for the price of a G-11 or a CGE Pro and will handily outperform either one within its load ratings.

That's fine...except...in my experience with the Losmandy mounts is that they and the CGE Pro (NOT CGEM) are very comparable in quality. With the edge in some respects going to the Celestron.

What I hear being said is that the G11 is higher quality than the CGE Pro but lower capacity, right? On the other hand, I've read several reviews that state neither one is exceptional in quality.

I'm guessing but the CGE Pro is likely made in China and the G11 is USA made. I have one on order that is simply awaiting a tripod before shipping. I don't yet have a pier so a tripod is required for either mount. But if I can get a $5K CGE Pro for just $4K, isn't that a pretty good deal? Only one vendor is selling it at $4K and I don't know how they can knock a thousand bucks off the going price. Seems maybe I should snatch that up just on principle... )

Also, I do like the quality and build of the CGEM. It is a substantial mount and seems to track well. If the CGE Pro has quality anywhere near that, I'd go with it. Celestron has been a very supportive company, too.

I hear people cutting down the celestron mounts all the time and my little CG5-gta does what everyone seems to thing it couldn't possibly do. So I say if you found a good deal might as well get it. With proper setup I bet that mount will serve you very well.

Ralph, agreed. Anyone who mocks something like the CGEM or CGE Pro simply hasn't tried one. My CGEM is remarkably sturdy and does what I want it to do when I want it to do it. I use Starry Night to drive it and it goes where it's pointed. It is on the tripod it came with and even fully extended, is incredibly stable. If anything will disturb imaging, it is my observatory floor's flexure. But the CGEM is just overloaded now (for AP) with the 120mm SkyWatcher, an 80mm Orion short tube guide scope, a massive 2.5" Moonlight focuser with digital motor on the Skywatcher and a 2" Moonlight focuser with motor on the Orion.

If I were just doing visual, the CGEM would be fine but I am a perfectionist when it comes to CCD imaging and I'm also thinking about the future of my hobby. I may want to put a bigger OTA on the mount someday and that will likely break the CGEM's stability.

The problem is whether I can convince the wife to let me spend this kind of money even though it is a huge savings over usual price. I may have to sell my LS-8 ACF AND the CGEM to convince her.

I'll just say this and leave it alone. I have used all three mounts, the Pro, the G11, and the Titan. All are good mounts and good values and very similar in quality.

The CGEM had a (very) rocky introduction. Now? If my Atlas stopped working I'd replace it with a CGEM in a heartbeat.

I owned both g11 and now a newer Titan 50 and have used a cgem and go out imaging with a friend who bought a Cpro last year..

IMHO.. the Titan has the best build and is a very solid imaging platform, my old g11 was great but like already stated here.. I needed a mount that can carry an ota&acc. near 50# so bye bye g11..

I wouldn't give a cgem another chance seeing how they ran (in the past) and have to rate the Cpro as a nice doable mount.. outside some quirky electronic problems that my buddy experiences from time to time and that he had to send his Cpro back to celestron while it was under warranty to fix a wonky drive motor board and remove some stiction in the RA.

He says the mount is better and he still requires to reboot the mount when it suddenly freezes the odd time..

He also addressed the issue of having the mount so high up by taking the legs to a machine shop and cutting 6" off, making the loading a 12" sct a much easier task.

We both do mobile imaging so hauling a Titan into the field as well as the Cpro take the smae time to setup and dissmantle.

hope this helps...

Thanks, all. I built my observatory so I wouldn't have to lug the CGEM around. At 50 lbs for the motor head alone, it's just a bit too much to be "portable" - I'm not a big person. The CGE Pro would be even worse and I can't imagine it as a portable mount by any stretch, not to mention the setup and breakdown time.

Frankly, my CGEM is now almost at Celestron warranty repair. Mostly my fault. I did an MC update of the firmware and at the end of the flash the mount tried to slew around with the clutches engaged and the roof of the observatory closed. I was afraid I'd damage the telescope so I shut off the power in a panic. As a result, I lost any ability to communicate with the motor control board on the COM port or the hand controller and reflash the firmware. Only option was to ship it back. They won't even get the mount until tomorrow sometime via UPS (which they paid for). So I'm without a mount and yancy to be imaging.

I think I'll just wait for it to come back and go from there.

Rod, really enjoyed your blogsite. I like the book series you've published with - I'll have to check out your book(s). I got to know Adam Stuart from his book on imaging from the suburbs and he and I regularly communicate via Facebook now.

Later...

Hey Kev, here's a quick question for you: Based on your experience do you think the Titan can handle a C11 Edge and a TEC 140 side-by-side for imaging? This would be about a 60 pound payload with everything aboard. Thanks!

Brian

It can handle the weight but balancing a side by side maybe an issue,,, you may want to run the tec on top of the C-11 it is much easier to adjust balance... the Titan is rated for 100lbs of ota's so it can handle the weight but the mount is known for being balance critical...

Personally I have not expirenced that problem as I usually off balance my setup in one direction by a lbs anyway, and almost always shoot an object from 50 to 80 degrees.

Jeff--

There is a seller of a CGEpro on Amart for $2.2k

a half-way solution for you could be to buy a used CGE like this one, save $2-3k and probably be out less than $1k after you sell your CGEM... not a bad trade idea...

Being comfortable with the CGEM, I think that you will probably be happier with the CGE Pro than the G11. In addition, the G11 does not really give you much more capacity than the CGEM. Neather are great mounts when it comes down to it but the CGE Pro has clearly seen some improvement. The biggest difference is probably in consistency with the G11 winning there. Fit and finish on the G11 is better, but that doesn't matter when it comes to design issues. If you can get a CGE Pro at $1000 off its normal price and you are permanently mounted, then I would go for it.

Sorry, no. The one to which you linked is NOT a CGE Pro but rather a CGE - American made and discontinued some time ago. It's a nice mount. Mine has worked well for nearly six years.

I tried everything to get the COM port to talk to the mount. Finally, I got Celestron support to issue an RA# The senior sales rep for Celestron, Daniel Mounsey, called me not long after and said he'd make sure the mount got priority attention.

Today I bought a brand new Celestron CGE-Pro as I was talking about. YES!!! Can't wait to get it in teh observatory. $3999 with free shipping.

Mine is about 3 months old and is permanently mounted in an observatory with a C 14 HD and an 80 MM APO on top. It needed 88 pounds of counterweight, but is extremely stable. It is on a 14" concrete pier anchored to 2 1/2 tons of concrete buried below the frost line. It is definitely not portable in my opinion.

Goto is excellent. With a quick polar alignment, it finds targets to within a 200X eyepiece field every time. I have not tried AP yet, but it works just fine with my Mallincam on under 1 minute exposures. The hibernate feature is great and saves time. I have not yet tried high precision pointing.

After some initial alignment difficulty, it has been perfect. Lou

I'm perm side by side with my cge-pro..

8.75lb ride on top of the 80mm to get the balance just right..

I use TheSkyX.. just got finished with my polar alignment and a 345 point t-point run.. whew... Just got the mount back from our friends at Deep Space Products. The CGE Pro got some Hypertune TLC and a little massage from aeroquest..

Got it within 60 arc seconds.. I could get it closer but the latitude and azi adjustment can be a major pain in the rear end plus I autoguide anyways.... I've done it so many times now, I can get it pretty darn close in one night..

Click on Ed Thomas's link above. (The website is probably down...Hurricane Sandy strikes again! 10/30/12)

It's a procedure where the mount is cleaned out of all that bunk "chinese" grease and bunk "chinese" bulk manufacturing defects are "cleaned" up. Makes the mount much smoother and quieter.

You can also upgrade gears, etc.

The HyperTune® Standard telescope mount service includes but is not limited to:
Complete inspection of the equatorial mount head.
Complete dismantle of the equatorial mount head.
Inspection and cleaning of each telescope mount part - removing all metal burrs, shavings, thick grease and foreign objects.
High resolution sanding and polishing of moving internal parts to a mirror-like finish resulting in high smoothness of internal metal parts and “glide like” performance from your telescope mount.
Inspection and adjustment of motors and encoders with gear set screws replaced as necessary.
Reassembly of your equatorial telescope mount using high grade synthetic grease.
Resetting of worm gear meshing.
Adjustment of backlash settings in RA and DEC.

The altitude and Azimuth adjustment can be a major pain in the rear end. Especially with weight/OTA on the mount.

Adjusting the altitude can make it shift in Azi since the adjustment is this knob/bolt. The bolt can shift side to side on the plate (instead of up and down). I find it easier and more precise by lifting the counterweight bar and then turning the knob and then resting the mount back on the knob.

It had not been set property at the factory. I called Celestron, and a neighbor who has one came over to help. Simply erasing the memory and restoring factory defaults through the utilities corrected the problem. The gotos are right on and alignment was simple. Lou

Thanks, Lou. This mount is coming straight from Celestron in Torrance, CA so I'm assuming they've checked it over. I do think I'll hold off on the Hypertune until I get to a time when the weather isn't going to be good for scoping - for about a month or so. I suspect the mount's grease will work just fine for a while. I'm not so sure that Chinese grease these days is all that bad. I sell Chinese made high-end ukulele online and I have to say that the quality of those instruments often exceeds custom made ones. I also have some Chinese made optical accessories that are just phenomenal. Japanese optics used to be what one aspired to in that region, now, who knows?

BTW, all, I've been advised by the vendor I bought the CGE Pro from that Celestron is having a $1,000 off sale on all CGE Pro configurations beginning Thursday. The vendor is Hands On Optics in MD. And I am really pleased with their customer service so far. They're up there with Agena Astroproducts as far as service goes.

I would think that one only need adjust the Alt once, unless you're moving it around. Same with the Azimuth. Luckily, I will be putting this in my observatory on its rather sizeable tripod for the moment. If it works out and I don't have to ship it back to Celestron for warranty work, I have a friend who will weld a permanent pier system for me.

There is a sale this month on the CGE Pro, $1,000 off:

https://www.astronomics.com/celestron-cge-pro-heavy-duty-...

Likely it is other places, too. I'd be tempted but I just bought and am waiting for first light on an ASGT. Got a good price on it and -- with me being small and 76 in two months -- the ASGT is plenty heavy and will support my scopes (80mm APO, 5" C+ SCT, 8" SCT) well enough.

Correct, Phil. Celestron is offering all CGE Pro configurations $1000 off through the end of November, I believe. It was that sale that allowed me to pull the trigger on buying it. I just happened to find the pricing before it was announced.

BTW, the mount arrives today! Figures the barnlot where my observatory is located is a big muddy mess from the hurricane's overflow. So The mount will come inside the house until things dry up a bit. I could just see me sinking deep into the Ohio clay trying to carry that monster mount out there...

Yah if you can pick one up for that much of a savings it is really worth it. I am looking for a used one then I will send it to Ed and have him rebuild it for me. I really wish the CGE-PRO had internal cable routing but you can't have everything.

Whenever Celestron drops their prices by 10% I come close to buying one with a 11" EdgeHD. The savings almost covers a hyperstar.

Maybe there will be some extra good deals at ASAE next weekend. Starizona has no excuse not to be there.

The mount arrived Friday afternoon. Two huge (and heavy!) boxes and one little heavy one with the counterweight. The longest box had the massive tripod. I could carry that from the UPS truck to my front porch but the driver had to help with the mount box - it was 107lbs. Since my observatory is about 100 yards behind the house I used a wheelbarrow to move the separate parts out there after unpacking them. I set up and leveled the tripod, the electronics pier, and then manhandled the mount on top. I attached everything with the 6 screws provided and came indoors.

Reading the manual, I discovered I'd put the electronics pier on about 180 degrees out from where it was supposed to be positioned. All I had to do was undo the screws and turn it. When in doubt, RTFM (read the manual). I plugged it in and fired it up. Right off the bat I realized it didn't have the index marks that the CGEM has. Instead, the HC asked to find the "switch". The manual said nothing about what this switch was or what I had to do. So I shut it off in hopes I could find an explanation somewhere before going through a process I didn't have a clue about.

Came down with a nasty flu so I haven't had the energy to go out and play with it further. I don't even have the OTA on it yet. I hate winter and the cold...

Just turn it on. It will seek the "switch position" on it's own. You are then ready to align.

I found it difficult to align the electronics pier with north. My scope is observatory mounted on a concrete pier. I had to adjust the mounting of the electronics pier to the base plate of the pier several times before I had it in a close enough position that I could achieve polar alignment with the rotation adjustment screw. It is a real oversight in my opinion that the electronics pier does not have a marker on it that says "north".

The altitude screw is a bear. Hold the OTA up when adjusting to take some of the weight off of the screw. I literally had to use a pipe wrench to adjust it.

When you start to align, if it misses the first and second alignment stars by a wide margin, go to utilities and restore factory defaults. It should work fine then.

Good luck. Lou

Thanks, Lou. But what is the "switch"? Something to do with the encoders?

The manual says to align the electronics pier so that the RA and DEC cable plugs are on the east side. I have the tripod set up so that the leg under the bubble level is pointing north. Once the OTA is on it it should be pretty close to polar aligned. I'm sure I'll have to fine tune it. The latitude (alt) pointer seems to be a bit ambiguous. There isn't a fine point but rather a rounded edge. Once aligned, who cares what it actually points to, I guess.

Jeff,

There are micro switches on both the RA and DEC axis. The switches are tripped by physical indentations on the shafts. They provide a solid reproducible starting point for the mount. The CGEM on the other hand uses soft index marks (only markings on the outside of the mount), if you used those marks great but you didn't have to (the mount never "knew" where the marks are ... it just assumed that you were starting using them).

With the Celestron firmware you can setup an arbitrary home position for the mount. That can be any appropriate position or it can also be the same as the switch's home position.

One of the benefits of the physical switches is in remote operations ... when the mount it powered off and then powered back up it will always know where it is ... and this isn't the case with the other mounts that have the soft marks, they can be powered off in any position and the mount won't know that when it's powered back up.

Sounds good, Jeff, except the flu part. No observatory here in metro Los Angeles. Serious viewing means a long drive to mountains and deserts. Your new CGE Pro sounds like a move it once and leave it there proposition. Good you were able to get such a nice discount on it

This mount is coming straight from Celestron in Torrance, CA so I'm assuming they've checked it over.




Jeff, that means it may have shipped from 3 miles ESE of my location -- also in Torrance. I've had very good luck with Celestron. My new ASGT arrived from Oceanside (OPT) 50-60 miles away. I'm struck by how well finished it is for the price ($630 or so plus tax). My Alt-Az mount (NexStar 8SE) does not seem quite as clean. My earlier scope (NS8GPS -- given to a local astronomer who could handle the size but not the price) also seemed well made. The ASGT (fired up indoor a couple of days ago after receiving the NexStar+ HC from OPT) seems to run properly and more quietly than I expected (payload now is WO ZenithStar 80 FD, my smallest scope).

Thanks, everyone for the advice and tips. Now the switch concept makes sense. That must be the little clicking noise I hear when I loosen the clutches and rotate the axes.

I got the SkyWatcher on the mount late yesterday but still didn't feel well enough to play with it. I did get some photos that I'll post on Facebook.

Switch clicking. yes.. Normal when rotating axis..

The electronics pier can be put any which way you want as long as the bolt holes line up... It doesn't matter It's a cylinder... Ideally you would want the RA and DEC cables on the east side unless you want cable wrap... Sigh...

Observatory here in metro Los Angeles. If Phil is 3miles ESE of Celestron, Phil must be very close to me.. I'm 8miles ESE..

The mount head, you want the CW pointed north..

Yeah, the pier will go any way you want, but the cable jacks should be on the easterly side or they'll get wrapped up badly. They could have made them a tad longer. I also wish they had included an AC adapter. For a mount in this price range a $60 adapter should have been included. Instead they give you a cigarette lighter power cord that is extremely long. There is no way I'm going to be plugging this mount into a cigarette lighter. That worthless (to me) "accessory" will sit in a box for years until I throw it out.

The counterweight is pointed north - when the scope is rotated up. This is the "home" position so that the roof can roll back without hitting the scope. Almost closed the roof with the scope rotated up once. Talk about panic...
