I’m looking forward to a 1Q22 delivery of my SVX140T and considering an ALT/AZ mount. Stability & lack of shakes is the most important thing. The tripod is a Berlebach Planet. 
 

I realize there aren’t a lot of 140s in the wild; perhaps someone has some experience with a TEC140 or similar with the same setup?

 

Any recommendations and experiences will be helpful. Thanks!

I'm sure you'll get the 'usual'... DM6 etc or perhaps a SkyWatcher EQ6-GT.

 

Personally I like a manual alt/az as a change from the computerised imaging gear. A Nexus WiFi device reads the encoders and send the info to my iPad running SkySafari. It is revolutionary (although I still like to use a paper atlas at times!) Sweep to which part of the sky you want... no waiting for the mount to slew, no de-clutching, etc, etc...

 

I have a TEC140ED riding atop a fully equiped Half Hitch Telescope Nova Hitch alt/az mount (also on the Planet), which I can highly recommend. Unfortunately these are out of production as the maker, Charles Riddle passed some years ago, but I do see them come up on your second hand State-side astro shops.... you may even be lucky to get the last mount he made, the FTX-V2.

 

Perhaps even a T-REX..?

 

If not, the Rowan AZ100 has a very good reputation (both on here) and SGL:

But none have the Half Hitch Telescope mount two-axis balance philosophy....

 

Good luck with your decisions!

Clear skies,

Super Mount KR makes the W Master alt/az mount. It handles up to 55 lbs. They post YouTube videos of their products in action. I watched one the other day where the W Master mount is supporting a Celestron C14

I use my TEC 140 with a Rowan AZ100 on a permanent pier and also on an Ioptron Tri-Pier with great results.

William A. Paolini did a field test of the NOH CT-20 ALT-AZ MOUNT and his extensive report is available on the CN Home page.

 

While I do not have this mount, it may be able to handle your forth coming scope.

I read that yesterday, looks pretty good. I was a little worried about the 2.5 second settle time for the 152, but the 140 should be better.

Dave, that's honestly the way I'm leaning. Can I assume by 'great results' you mean the focus shakies and settle time are minimal? 

 

Thanks T.J. for pointing me at the W Master.  Perhaps W stands for "Wood"?  :)

 

Damian, I can only say I wish Charles Riddle was still among us.

 

Anyone have experience with the Losmandy AZ8?

I have W Master mount.  I use it for 130mm f/7, f/9.2 and 152mm f/8 refractors.

It works really well.

 

I saw video demonstration with CFF 200 (f/6.5?) on W Master.

Yes, settle time after a slap on the diagonal is less than a second. Focus shakes with the Feathertouch are pretty much a non-issue.

 

I considered an AZ8 but decided against it when I found out the azimuth slow motion doesn't rotate with the mount. It stays in a fixed position so it would be pretty hard to reach most of the time.
