New CG-5/AS Owner... What should I know about it?
      #4336703 - 01/24/11 12:54 PM

Hello all,

I just bought a new CG-5 Advanced series ($599 shipped from OPT. Invoiced marked "Clearance" - fuel for the replacement speculators).

I'm familiar with the Celestron HC and its capabilities, so I'm fairly competent with that. I'm wondering what everyone's thoughts are on load capabilites or the CG-5. Right now I have my old C-8 mounted on it. I also have a C-9.25 I was hoping to use on it as well.

Any ideas on what I should do to the mount for best performance? Any mods or recommended accessories?

I did replace the top piece with an ADM adapter and the ADM combination clamp (Losmandy and Vixen compatible) - the one that uses two spring-loaded screws and clamps to the 'scopes mounting bar with its entire length, rather than using just the pressure of the screw head.

Thanks,

Doug

Interesting. Plus the OPT on line price was $650 last week when I looked, or I would have driven to Oceanside Saturday and bought one (Woodland Hills had a lower price but none in stock at the time). WH is closer but Oceanside is about the same drive time due to traffic patterns -- and more scenic

Likely there are some threads here on improving the ASGT aka CG-5 GT mount. I'd try a search in the Mount forum using each of those search terms.

And be sure to look in the Forum Archives:

since the CG-5 has been around a while.

The $600 price seems to be the going price. I bought my first CG5ASGT from OPT in March '08, my 2nd from Hands on Optics in April '10. Both were $600. I presume that there are so many of these produced by the manufacturer and stocked by the dealers that discounted sales are pretty common.

I'm also a new CG5 owner. I got mine about 2 weeks ago from OPT. The price then was $599. Looks like they have gone up $50 and no more free shipping. You were lucky to get it at the price you did. Anyway, the first addition I made was like you. I replaced the stock mounting bracket with this adapter. It is rock solid and should hold the telescope securely. I say "should", because I haven't gotten to use mine yet due to the weather. I did add a StarGPS, but only because I already had one for my Nexstar 11 (the NS11 has been trying to 'link' for the past 5 years and finally 'linked' about a couple of months ago, but that's another story). For now I can't think of anything to add. Do you have vibration suppression pads? I'm going to use mine for awhile to see if there is anything else the mount could use. Let us know what you do with yours and post pictures if you can. I love to see what others have done to enhance their equipment.

If it has the black "Synta Glue" in it, replacing the grease would be the best mod. You don't have to do a tune up on the mount to get rid of the lousy grease.
Some people have shortened the tripod legs, I replaced mine with a heavier wall tube which made it a little more stable.
I use my ASGT with my 6" refractor which tops out at 32lbs with no problems.

Noisy bugger it is.

Other than that, I've used one with a C925 for visual purposes successfully. My only counsel would be to be certain you have the scope balanced properly to get the best results. I ended up marking the dovetail based upon what I added to the OTA to ensure I could do it easily, especially after sunset.

1. Leave the mount alone unless it has a problem internally.

2. Spread the pins on the mount side connector to ensure good contact.

3. Always run with a good, fully charged battery.

What Rod said. On #2 he means the pins in the power jack on the mount. Just a very minor spreading is required. Do yourself a favor, if your power plug is the straight kind, replace it with a right angle type.
If the mount goes crazy on you during the night while using it, refer to Rod's rule #3.
And you'll find the Synta glue/grease is a thing of the past. There was none on my CG-5ASGT, bought in late 2006, and still running like the champ it is. Great mount.
Load rating seems to vary according to who you are listening to, but I never exceed 20lbs on mine. It just works better when not heavily loaded. Balance is critical should you wish to exceed that amount, which the CG-5 can do.
The mount tracks accurately, and when aligned correctly the Goto's are highly accurate.

And as a shameless plug, but not for me, buy Rod's book on SCT's. I bought two, and donated one to my local library. It is chock full of good info.

Doug, do you know where you can get a right angle plug?

Which version did you get (there seem to be three) and for what scope?

I got the dual version. I am going to use my Televue 85, which I already had on a D style dovetail, on the CG5. Here's a picture of what the ADM system looks like with scope mounted.

I don't want to hijack this thread, but would the right angle adapter you got, Doug, work with the Celestron AC adapter? I noticed that Scopestuff said their adapter would only work with their AC adapter, not the Celestron AC adapter.

Mine had to be hardwired in to replace the original straight plug. I used to be an electronic tech, so soldering wires is pretty easy for me.
The Scopestuff adapter would seem to be just plug and play. Companies say those sorts of things to protect themselves from lawsuits should something go wrong. Lawyers made that necessary, with their unbridled enthusiasm for litigation.

The ScopeStuff plug is designed to adapt a 2.5mm plug (used by Meade) to the 2.1mm plug used by Celestron. So it won't directly connect to a straight 2.1mm Celestron and therefore is not "plug and play." It has nothing to do with lawyers and the lawyer-bashing comment is inappropriate.

Of course you can cut off the existing Celestron straight plug and the 2.5mm female plug and just splice the wires, which is apparently what is needed with the alternative product.

Personally I've never had any problem with the stock straight plugs on my Celestron 12V power cord and on my Celestron AC adapter. My approach is that if it ain't broke then don't fix it.

It's always appropriate, and besides, I wasn't bashing them, just stating the obvious.
