I will soon be downsizing some of my equipment. In my mid-70's, I no longer enjoy nor use my Esprit 120 and my Losmandy G811. So, from mount perspective I am starting to look at possibly a ZWO or Ioptron harmonic mount or possibly an Ioptron CEM 26. I will be loading it with either a SV105 or an SV80L. I need a mount that can 20+ lbs or equipment. However, I am visual only. I'm asking for comments, suggestions or experiences that the forum may have and suggestions on what direction I should go.

I admire and drool over those Berlechbach German wood tripods.  They are so beautiful and well crafted.

 

If I were interested in pure visual observation then I wouldn't hesitate about purchasing one, new without a tick or blemish.  I believe tgat they are lighter to transport or move, but again, I don't have one.

I was going to suggest the IOptron AZ Mount Pro, but I see that you already have one.

 

Are you looking for something lighter?

If have the funds "harmonic driven" mounts are very interesting also because do not need counterweights.
I would start with the mount and see if am happy to handle it with the 120ed: downsizing to a 100mm IMHO does not make a terrible difference.
If are on the other hand set for a 80mm may go much smaller (for visual even the smallest ioptrons may be enough).

Is there a specific Harmonic Drive mount that appears to be easier to operate? These mounts represent new technology and I would like to feel most of the "bugs" have been solved.

Just recently turned 70 and started to do a similar project.

Sold the Esprit 120 and replaced it with the SVX102d which is now mounted on the CEM40. My AZMP also handled the 102 with ease.

I still have the 15" for deep and the C-8e for planetary, doubles. With wheels i just roll those out of the garage

And for road trips the Esprit 80 on an Stellarvue wood mount w/AS dsc.

That is some really nice setups. How reliable have the Ioptron CE mounts been for you. Can the CEM25 carry the SVX102D without problems for visual observation.

The Losmandy GM811G is the most reliable mount you've mentioned so far.  Maybe consider getting the RA extension kit for it (so it comes apart for easier carrying) and stick with it...?

To the OP, I would strongly consider a harmonic mount. I have the Rainbow Astro RST-135 and the iOptron HEM27EC, which both weigh about 3kgs, but have stated payloads of 13kgs, or 18kgs with counterweights.

These mounts are rock solid, do not need to be balanced on the axes which are strain waves (the HEM needs to be balanced on DEC) and generally do not need a counterweight. Quite apart from being really light, they are very quick to set up!

For visual, I would check that the mount you go for has an Alt-Az mode (like the RST-135) or can accommodate a polar scope if you want to use it in equatorial mode and not use a computer to polar align it (a limitation of the RST-135).

The RST-135 is good enough to image with an Edge HD 800 without counterweights, so it should be plenty good for visual with the scopes you mentioned! I hope this helps.

I had my CEM25 with this ES 102 for ap. Mount handled that one well. For vis it should be no problem.

I would recommend a strain wave (harmonic) mount as well.  The light weight of the mount and not needing a counter weight is a huge advantage.  But the thing I’ve found that I really like is how very solid and stable they are. I have an AM5, and I’m very happy with it.  The Rainbow mount has a good reputation as well.  I’d also look hard at the upcoming Pegasus model.  As a visual only user, I’d think any of these would be a great solution.
