Tri-Pier Compatibility w/AM5N

I'm considering buying an AM5N soon and am looking at the Starfield Tri-Pier 1000, which comes with a 3/8" mount adapter. Currently, I'm only putting my Redcat on it, but eventually I'd like to put an Askar 130PHQ on this setup.

Two questions:

1) Can this setup manage the weight of this Askar (or ZWO FF130, they are the same) astrograph?

​​​​​​2) Do I need to buy the ZWO PE200 pier extension?

1. Yes

2. No. I have seen one in person and will be too high with a PE200

My configuration includes an Askar 107PHQ (a few cm's shorter than your 130) on the AM5 with the ZWO TC40 tripod and the PE200 pier extension. I operate from a hi-rise apartment balcony and travel to an observatory site 45km distant… so this configuration works well for me. 

The AM5 will  cetrtainly manage the Askar 130PHQ however you will most likely need the PE200 pier extension; I need it with my OTA and ASI2600MC-P attached - without the pier extension, my OTA/cam would hit the tripod leg while imaging higher altitude targets…. also allows for comfortable vertical slew to take my flats calibration frames. 

There have been incidents reported on other forums of tripod-OTA collisions without using the pier - be safe-not sorry…. and enjoy your 130PHQ.

I mount a Tak TSA 120 with feather touch focused , D plate, rings, and visual appliances( diagonal, eyepiece etc) on my AM5. I use two small counter weights on the shaft. I have the pier and extension. It all works perfectly all night, or all day when solar viewing.

I second what rbr27 just wrote. I have almost the same combo 107PHQ+TC40+2600MC Duo and PE160. With an 130PHQ I’d most certainly put it on a PE200.

I have the iOptron tri-pier and the PE-200 isn’t optional…

If you do end up getting the Starfield pier, you need to make sure you get the iOptron adapter plate as well

The PE-200 serves as the adapter to mount the am3/5/n to another iOptron compatible tripod…

I wouldn’t hesitate to just use just the 3/8” bolt with something small like an 80mm scope or redcat but there is no way I would risk it for a scope over 100mm… (I frequently use my AT130EDT with my am5)

Guys, please read the post carefully because you are providing wrong advice. This is my advice based on actually dealing with both the starfield and an ioptron tripier

- if you get the starfield, get the 3/8 plate, goes directly into the AM5n, do NOT get a PE200, will be too tall and unnecessary

- if you get an ioptron tripier, those do need the PE200 to adapt to the AM5n

- you could get away with the large refractor in a TC40 + PE200 as others point out. I did for a while. However got a lot better guiding once I moved into the tripier.

For what it’s worth, I’m upgrading mine to a cq350 on the SW tri pier. This just doesn’t feel solid enough.

I'd have to agree with Dompe's replies. The Tri-Pier's legs are so far down from the mount that you'd have to have an exceptionally long bit of gear to have it foul them. If you like to think of it this way: the Tri-Pier already has its own extension built in.

I use an AM5 on a TC40 tripod, and I use ZWO's PE200 extension simply to ensure that my longer refractors + imaging train don't foul the tripod legs. I also use the counterweight shaft and a weight (or two) for my bigger imaging rigs. When I am using my PHQ107, I add 1 x 5kg as a precaution, but the AM5 (and even more so, the AM5N) really doesn't need it - I'm afraid I'm a bit of old school, and I think it pays to reduce the load the mount has to contend with, and provides improved stability especially when the OTA is well off axis. This arrangement has not been a problem for me, and the AM5 copes quite well, and also with heavier rigs + 2 x 5kg counterweights.

If I were you, I'd put my money into an extension bar + counterweight, rather than the PE200, if you are buying the Tri-Pier 1000.

I hope this helps,
Paul.

BTW: I've refrained from including a photo of my kit as it differs in only minor detail from the gallery of photos already displayed here. If you think it would help, I could do this, though.

I think I know where you are coming from.  While the TC40 tripod is a wonderful, light and easy to carry in tripod, I was getting sick of having to polar align my scope everynight after I took my telegizmos365 off.  I decided to try and find something more sturdy and found a Ioptron 360.  Here is a picture of it (on the right) with the P200 pier extension and my Redcat 51.  I havent had to polar align again since the night I set it up....

P.S. I have also mounted my Tak FSQ106 and EdgeHD 11" on it with no issues.

Scotty, very nice set up.  I already have the P200 extension, if I bought an Ioptron 360, what additional adapters would I need to mount my P200 on the Ioptron 360?  Thank you. Jeff

I used this Jeff:

https://www.printables.com/model/329484-zwo-am5-pe200-pier-adapter-for-ioptron-piers

Took about 1.5 hours to print.  If you don't have a printer there are places like craftcloud that you can get to do it for you.

https://craftcloud3d.com/

if you aren't comfortable with that... I could be persuaded. ;)

Scotty, thank you for the information.  3D printing is outside my wheelhouse, but it looks like an amazing technology.  Ill get back with you if I pull the trigger on a new Iopton pier.

I use the TS TriPier with a customized 3/8 adapter plate. I drilled out holes in the plate to mount the AM5 using its three bolts.








The tripod bag of the TC40 is placed underneath the leg spreaders for the power and cable stuff.



No more collision risk at zenith.

Here are some pictures of my WO Mortar 1000. I dont know why WO stopped making these. I can only assume that the timming was off in terms of marketing since the AM5 had not yet been released. I actually picked mine up at a discount. Picture below with my RASA 8 and ES127 FCD100.

Solid mount. I also have an Ioptron tripier that i use with my new AM5N and Edge 11.

The WO pier is the same as the TS one. They're all from the same OEM manufacturer, just branded differently.
The TS pier is still available for purchase.

One of the nice things about these forums is that you can end up learning a lot. In my case, I have a couple of long refractors (with imaging gear attached) that foul my tripod legs near zenith. This discussion has alerted me to what was available to get around this problem, and by inference, people's experiences with them. The upshot is that I have now ordered a TS-Optics Tri-Pier with EQ6 adapter plate (see: https://www.teleskop-express.de/en/mounts-tripods-rings-rails-power-supply-14/tripods-piers-polar-wedges-80/ts-optics-tri-pier-tripod-height-950-mm-weight-only-8-kg-13985).

So, thank you all for your inspirational inputs. I, for one, have benefitted.

Likewise. I ordered the Tri-Pier as well l.

Thanks for all of the input here! 👍🏽

Another thing I learned from this forum discussion is that others follow a different practice to myself w.r.t. placing their dew heaters. So, I have raised the following discussion: https://www.astrobin.com/forum/c/astrophotography/deep-sky/so-where-is-the-best-place-for-a-dew-heater/?page=1#post-178446. I hope you find it interesting.
