Hi all....
I'm not new to this, but there is way more knowledge, experience and valid opinions out there among visitors to this forum than I could ever duplicate in a lifetime of trying.

I recently purchased an 80mm EON. Very nice scope! I had it out with my Atlas and had some great views with it and the Atlas seemed very happy... :lol:

But there will be times when I want something lighter and more portable.
It must be GEM, have GOTO with enough quality and load capacity for light astrophoto use. My Atlas can handle the more serious attempts...

I have had a CG-5 in the past and found it to be a very good mount, and would buy one again, but not before putting the question to the group for alternative suggestions.
The noise of the CG-5 is not objectionable, so does not need to be factored in.
Price range under 1k USD

Thank you for any input you may contribute.

I use my shorty 80 on my Super Polaris and it works great.

I use my SV80ST on my CG5ASGT. It's a stunner.

Yeah I use my LXD75 for my 80mm. It works great! I would guess either that or a CG5 would be a good choice.

The C5 ASGT is hard to beat (as is the Meade LXD-75, but I prefer the Celestron handset software).

If you are flexible and can accept the differences in the handset, an older Meade LXD-55 can often be had for less than $300 and actually has one huge advantage over the newer mounts. The flimsy tripod is only flimsy when used with heavy telescopes. for light telescopes, it actually is a great choice because it weighs about 7 or 8 lbs less than the steel legged LXD-75! The difference is that with an 80mm scope, lifting the entire mount, scope, counterweight, and tripod is a SNAP! This is especially true if you get one of the hugely expensive Vixen counterweights or one of the very light Orion counterweights which allow you to minimize the weight on the mount making it both more stable and easier to carry. Vixen sells 4 lb (or about) counterweights, an Orion sells a 6 lb (or about) counterweight. Using the stantard 10 lbs weight is way overkill. I will go out of my way to find the lightest counterweight needed to balance the intended scope for the mount. For example, I recently made an adapter to use an LXD-750 counterweight on my CG5 to balance my EdgeHD 8" on my CG5. I needed about 14 lbs, and adapting that weight saved me 6 lbs over adding a second 10 lb weight.

So, if weight saving is important and you can live with the Meade handset, a used LXD-55 is a great inexpensive light-weight approach with full Go-To.

Regards.

You already know the quality of the Orion Atlas EQ-G, have you considered the Orion Skyview Pro? It's capable of handling 20lbs with no trouble, is quiet, reliable, and has good Go To capability...all for $819 from Orion; an optional polar alignment scope also is available. It is essentially the Skywatcher EQ-5P (which actually comes with the polar alignment scope and more counterweight) that I own and have found to be an excellent mount (these can sometimes be found offered for as low as $500-$550, an awesome deal!) An additional benefit is the fact that both the EQ-5P and the Orion Skyview Pro, being Synta built mounts, can use the powerful EQMOD system for mount control...a terrific bonus. Good luck on your hunt and I hope this helps. Clear Skies, BrianB :usa:

Thank you all for your kind words and opinions!
The CG5-ASGT would be an easy buy, as I have already have had one. I did not like the poor fit and flimsy construction of the plastic used as a cover surrounding the drives and electronics. In all other respects it was a very easy to use and serviceable mount. I'll have to take a look at the other suggestions and see how I feel about them.

Again, THANKS! :bow:

Alan,

I also own the GC5 and I agree with you the cheap plastic pieces over the motors suck. The Dec housing on mine actually got stuck on the dec lever and ripped the housing apart causing my mount to go to Celestron for 45 days.

I haven't had any problems with the LXD75 but it does develop some backlash after using it so every 4-6 months I take the motor housing off and tighten the worms. It really helps out. For the price the ASGT and/or LXD 75 are excellent mounts not G11 but good entry level go to mounts.
