Get the 119FSA.
 
You will have to add a 10-12" aluminum disc or plate as well. You can usually find suitable 1/2" thick aluminum discs on eBay.
 
Using an intermediate aluminum disc will allow you to avoid making permanent changes/holes to your mount or pier.
 
If you aren't handy with a drill press and hand-tapping aluminum, your friendly local machine shop can help you. They could provide the aluminum disc as well, if you don't find a cheap one elsewhere.

I do not expect you to know the technical drawings of hole patterns of the PMX pier. I am pretty sure I will have to tap holes. My question was more geared towards versatility between AP1100 and Mach2.

The scope won't stress the mount, but it may not be as steady for visual as you might want. That's why i would go with the bigger 1100. You won't need the encoders on that mount, so it's actually a bit less expensive. Also important is the pier or tripod that the mount sits on.

For visual, the rule of thumb for refractors was that the mount's worm wheel diameter should be same size as the scope's lens aperture. Smaller worms take longer to settle than larger worms. That was the rule of thumb back last century ;^))

It will be only for visual with typical add-ons (finderscope, rings & plate, diagonal, eyepiece, etc.).  The 180FL will be about ~47 inch long. I saw that it’s still within the length & weight curve/graph posted on AP’s website for the Mach2. I just want to make sure that mount can be the permanent workhorse for the 180FL without worrying that the scope causes undue stress to it in the long run.
Thanks

I would expect the Mach 2 would carry your 180, but moment arm vibrations at the eyepiece is why folks recommend the beefer 1100 bearings.   The 1100 also breaks into very tidy lightweight components for easy transportation.    Nice decisions to have.

1. Can I use Tpoint from Software Bisque to create a pointing model for the AP1100 or do I need to upgrade to APCCPro?
2. Will the Losmandy HD tripod be able to handle the TEC 180FL on the AP1100? (38lbs scope + about 15lb cameras accessories + the mount ofcourse).
3. Is there a way I can mount the AP1100 on a Paramount MX permanent pier via an adapter?
1) yes, you can use T-Point. However you cannot use their Pro-Track feature for unguided imaging. APCC Pro does have this feature and many more.
2) Yes, the HD tripod is very rugged.
3) We have flat surface adapters that can be drilled to fit just about any pier or tripod.

I recently purchased an AP1100 from a user who got it from AP in the April batch (thanks to Astromart). This comes with the Losmandy HD tripod. I am expecting the mount (+ cws) next week.

I am also about to get a TEC 180FL next week (it has been shipped by Yuri), so I am excited to give the AP1100 a spin.

I am new to AP mounts and this one does not have AE, and comes with APCC (not pro), I have a Paramount MX and associated The SkyX with Tpoint etc.

I have three questions:

1. Can I use Tpoint from Software Bisque to create a pointing model for the AP1100 or do I need to upgrade to APCCPro?

Re: AP1100 GTO question

 

Regarding the question about Tpoint versus APCC, I highly recommend going with APCC. Not only will you get an improved pointing model but you will also get an improved tracking model which is pretty critical in my opinion. We have an AP 1600 with absolute encoders and are doing unguided imaging at nearly 3000 mm focal length and it’s essential

Yes, as John has said the Losmandy HD tripod is a nice solid tripod.  I use one. 

3. Is there a way I can mount the AP1100 on a Paramount MX permanent pier via an adapter?
Yes, you will need an Astro-Physics 119FSA - > https://www.astro-physics.com/119fsa

We have a 48" Software Bisque pier with an AP1100 bolted onto it using the 119FSA at our observatory.  You just have to drill down through the top of the SB pier and attach the flat surface adapter with bolts and nuts or drill and tap a threaded hole.

My ap 180 f7 rides on my 1100 and losmandy hd tripod no problem.  3, 18lb weights, plus rings, saddle, dovetail plates, finder, diagonal. 20 ethos, no problem.   I like the losmandy hd for the flexibility it offers with my other telescope configurations.

Subject: [ap-gto] #Mach2GTO - Can It Handle TEC 180FL?

I know many had suggested that the 1100gto to be the best candidate for the TEC 180FL refractor. However, I have checked AP’s website spec sheet for Mach2GTO mount and it does look like the TEC 180FL is within range - both in weight & dimension. I’m not really a big fan of mount overkill idea nor ready to drop $15k for a mount. So, my question is, can the MACH2GTO handle TEC 180FL at ease without any concern for longterm effect/issue? Per TEC’s website, the 180FL OTA should be very close to 40 pounds.


Re: #Mach2GTO - Can It Handle TEC 180FL? #Mach2GTO

1314 keystrokes follow
 
In some cases the length is more important than the weight.
 
Example:
 
Need a broomstick or something light, strong and a few feet long
Put a 10 or 20 pound counter weight on a horizontal broomstick so you can slide weigh close to you.
Hold arms out horizontal holding broomstick level with ground and counter weight close to hands.
 
Notice the torque on your shoulders to keep broomstick level with ground.
 
Slide counter weight out a foot from your hands
 
Notice the torque on your shoulders has increased to keep broomstick level with ground.
 
Slide counter weight out another foot from your hands
 
Notice the torque on your shoulders has increased to keep broomstick level with ground.
 
If the weight is too large or the distance from shoulders to weight is too long,
 you will eventually not be able to keep the broomstick and weight level with the ground.
The Torque on your shoulders is too much for your shoulders' muscles.
 
In this example your shoulders are your mounts' worm and worm-wheel.
 
Torque is a static and linear force and zeroed out if balanced.
 
Moment of Inertia (resistance to change in speed or direction) varies with
the distance squared from worm.
 
Length of scope can be more important than the weight of scope.

As always I may be wrong again.
