Be wary of the CG-5 carrying a C-11. My C-11 weights in at about 34lbs with guidescope and dovetail and pushes the limits of a 45lb iEQ-45. I've seen the design limit for a CG-5 put in the 30-35 lbs range. I had a C9.25 on a CG-5 one at one point back around 2005. I felt like that was the largest scope it would handle. A C-11 will be pretty top heavy as evidence by all those counterweights.

The CG5 mount is ok for an 8' SCT or maybe even a 9,25 SCT, but that's about the limit for the mount.

+1 for everything said, the C11 combined with those 3 dumbbells balancing it out makes that CG-5 look like it’s about to cave. I wouldn’t dream of putting a C11 on it.

Hit the guy up for $2000. If he bites, take the $500 you saved and put it towards a more suited mount.

Celestron did sell a C11ASGT but just because you CAN do a thing doesn’t mean you should.

I’ve got a couple CG-5’s and they are good mounts, but I wouldn’t go any larger than a C-8 on one.

I think the price is too high.

does this look like a better deal if I can get them down to 3200 or so?

A new 9.25 on an AVX is $2,949 (Celestron website price).

This seems like that familiar game where someone keeps throwing whatever they can find immediately used at us looking to see what we think of it without any criteria when instead you would be better to start with:

 

1. Prior experience with telescopes

2. Intended use both right now and in the future visual, photography or combination of the two or maybe you're not sure yet.

3. Transportation requirements, do you use it right where its stored, put it in a car, carry it up from a basement. Mostly used at home or do you plan to often go to star parties or dark sites? How much can you lift?

4. Budget. With the numbers you are tossing around you very likely have enough of a budget to get exactly what you want, but thats dangerous unless you know exactly what you want.

 

For example both of those ads you provided are nice stuff, but even the second one is seriously under mounted for photography and I just want to verify that you are sure an equatorial mount is really what you want if you are doing visual only.

Yes I can tell you I am somewhat guilty of all of the above.  I have been searching for about 4 weeks and have been following both of these for a  few days now.  I was originally going to buy just an 8 SE  but after searching I realize they are either OOS or I could do much better buying used in some cases.  

1.  I have been on and off again with telescopes for the last 20 years.   Never really had the budget to go bigger so always had some of the less expensive models including using binoculars to start.
2.  At first it would strictly be observing but there is a chance I could get into AP in the future as that is still TBD
3.  Right now it would be in the back yard but would definelty venture out into the country to find darker skies( my old house had much less light pollution than where I live today but is still not really in the city.
4.  This is the hardest for me ATM as I am not 100 % sure what I want.  I am 75% sure I want an SCT  what size that is something I am still deciding.  the 9.25 seems to be the right size for me from my research
 

I also see amazon now has 8SE's in stock which also might not  be a bad choice either


this is a hard decision and I am relying on people that have been doing this a long time to help me get my money's worth

Don't get the SE, with your budget you want an EVO, they are ridiculously better and hold the 8" much better and even a 9.25" if you want.

EDIT: I have the CPC800 which is the same scope on a stupid heavy 2 arm mount. You can see a ton with this with the only drawback being a somewhat narrower field of view (true of all SCT's)

I got around that by getting a 2" visual back and diagonal and then got 2" eyepieces which allow much wider angle views.  The 82 degree stuff tends to be the sweet spot between wide and heavy/expensive but I use mostly 100 degree stuff which costs a ton more and is like the holy hand grenade of astronomy (what I actually called my 9mm 120 degree eyepiece).

https://astronomy.to.../field_of_view/

Pick the 8" EVO and try different eyepiece combos to see what suits you.

2nd edit: Some 82 degree lineups switch from 1.25" barrel to 2" midway through so watch out for that.

Also consider the celestron F6.3 reducer corrector as a way to make a 1.25" eyepiece setup have a wider brighter view with the same eyepieces (with reduced magnification). you can actually select in in that field of view calculator

The 9.25" is like $750 more

I have a C8 on a CG5 and it’s a great setup for visual. However I’ll admit there are time I wish I had a 9.25 SCT on a CGX mount.

But over the years I’ve bought so many accessories that won’t work with any other rig that I’d be starting over completely if I made that move.
