Yes, that's what I meant - it's through-mount cabling, but only for the integrated +12V and USB
Having only one 12V port is a bit limiting though.

I would imagine it's intended to try to keep you in the ZWO ecosystem and is for the ASIAir - which would then go on to power/usb everything else.

Another option would be to something like a PPB - again that would then give you power/usb galore, all above the saddle with no cables to the ground.

Do any other mounts offer multiple power outputs?

2. Improved cable management
- by providing internal cables routed through the centres of the RA/DEC axes.
- not certain why they only mention the DEC axis ??
- with +12v and USB-C connections on the base routed through sockets on the dovetail plate.
- similar to iOptron CEM70 etc.
- no mention of how many power/USB sockets - having only one of each would be of limited use for most setups.


Actually the translation above said "Dovetail plate integrates DC output and Type-C port to effectively prevent cable entanglement" - which to me sounds like something more like a cheap version of the Pegasus power saddle?

Its not through-mount cabling.

This can be seen in the screenshot on the website mentioned above

Yes indeed they do ...
For example the iOptron CEM70G has 2 power ports on the rear of the saddle, and 2 more on the front.

The ones on the front are powered separately to the ones on the back - which is great for switching things like lasers and flat panels on/off remotely.

I'm not familiar with the  iOptron CEM70G - but it appears to be almost twice as expensive as an AM5?

No. I pulled the image from the OG link posted above. I also annotated in an attempt to reduce conjecture.

Indeed, but you didn't specify that in your question :-)

In fact we can go further and note that most (all?) mounts in the >10k region have all sorts of ports on the saddle plate. This is, of course, irrelevant to the present discussion. But if you don't set the boundary conditions you have to accept all the answers :-)

(sorry to be a pedant)

Yes it is more expensive, but it's in a different class of mount. Many larger/more expensive mounts have multiple 12V/USB ports on the saddle.
I wasnt trying to compare the CEM70 with the AM5N - just offering an answer to your question

If you have even 1 USB port, then you just add a quality powered hub and you're good to go. I have a Pegasus power box but that's really overkill from a pricing perspective.  Same with a single power port - as long as it will take 5 amps, I'm good to go with it. 

 So, I just ordered one.

I don't see anything important enough to make me splash the cash on a new AM5N, as opposed to the original one that I already own. Instead I went with a Juwei 17 at less than half the price to get my second rig going.

How does that mount compare to your AM5?

You really need just one port. The question is how much amperage will it allow. If it can support 5A it will be plenty for a PPB placed on the OTA that can distribute to miniPC and cameras. So that will elimante cable tanglement completely. 

The one thing I REALLY hate about the AM5 is the placement of the Power port for the mount. It sits on the RA axis and if you are using a counterweight you can have significant drag from the power cable. Or you could rout it from the back but there is still risk.

Time will tell, it should arrive in a few days but astronomical darkness is still some time away. Based on the experience of the earliest adopters it should perform very well.

In terms of capacity among other specs it's equal to the AM5.

I honestly think that just providing one 12v power and one USB port is sufficient… almost everyone is running a powerbox of some sort that's mounted to their scope… so being able to have a static cable that goes from the saddle to the powerbox is awesome… In the same way, if that USB port allows you to run a USB-C cable from your minipc/asiair into the saddle, and control the mount via that cable, you're essentially going to have 1x12v cable to power the mount, then every other cable is from from the saddle and up, meaning 0 chances of snags and drags and much cleaner overall cable managment..

I do something similar with my setup (Not on an AM5) but I have a powerbox and a mini-pc mounted to my scope, and 1x 12v dc cable goes from the ground to the power box (routed through the RA Axis, and 1x USB cable goes from the mini pc to the mount…. Its far and away the best power/cable management I've ever had. 

If I could plug power into the mount head at the base somewhere, and have a power out on the saddle, and direct USB to mount communication through the saddle, I would literally have 1x 12v power cable into the mount - and no other cables that weren't cleanly and tidily routed and attached to the rings/dovetails..

If you're really careful - it's not much benefit, but at the very least, it's aesthetically very nice to have no random cables dangling down from the scope.

Alex, you nailed it.  With the AM5N, you have a single 5V power cable to the mount, and the 5V and USB mount control to ASIAIR won’t ever snag again.  MUCH cleaner cabling.

Summary of key changes from original AM5 to AM5N:
  • 12V power and USB mount-control routed thru mount to saddle
    • Huge!  Completely eliminates cable-snag issues and makes for very short cables!! Yay!!

  • Periodic error reduced from +/-20 arcsecs to +/-10!
    • Still better total guiding error

  • Load rating increased from 13/20 kg to 15/20 kg
    • Now handles 33lbs without counterweight and up to 44 lbs with!!  From a 12 lb mount!!!

  • Added Bluetooth control option (like on AM3)
    • Now you can control AM5N with Bluetooth and keep your iPhone/iPad/Android device on WiFi or cellular for internet access

  • Redesigned base so azimuth adjustment does not need Az locks
    • Makes polar alignment even simpler

  • Moved altitude scale to front facing with an obvious arrow pointing to scale
    • Original AM5 had a recessed slot with hex-head that you tried to align…awkward!

  • Removed mini-dovetail mount from side of mount-body
    • That caused all kinds of cable-snags!  You only want to mount ASIAIR or other controller on saddle or telescope anyway

  • Richer, more elegant red powder coating.
    • Pretty!!

  • Carrying case changed from soft-case to hard-shell
    • Better protection, but some like soft-sided cases!

  • Dropped the bubble levels from oringinal AM5
    • They were especially nice (and important) for leveling in alt/az mode

  • Weight of mount increased from 5 to 5.5kg
    • A little heavier, but not much!

  • Note: Still requires hand controller for WiFi connectivity and control
    • Rumor:  WiFi connection integrated into mount:  untrue
    • Rumor: Hand controller now wireless:  untrue

I think it's a 12V 5Amp port. Should be enough for my portable systems.

Ross, my bad!  Yes, the power is 12V routed to the  saddle!  I corrected my post.

Also, the AM5N photo shows 3A available at saddle.  Which should JUST be enough to run ASIAIR+ (0.3A), 2600mc-Duo w/cooler and guide chip running (2A) and my 8” Edge dew heater at 30% (0.5 A)

close, but should work.

If the input is 5A 12V then why would the output be 3A 12V or are there actually two outputs? My 10 year old MYT had a small 1A 12V outlet that was part of the mount power that was useful for a powered hub or a focuser.

I don't like the idea of putting a computer on the OTA or the mount saddle. If you have a problem it's a nuisance to remove it and figure out what's wrong. There's nothing as reliable as a laptop in the field. After 14 years of imaging, I feel that wifi in the field (or even bluetooth) is just asking for trouble.

The old AM5 is the same - 12V/5A and 12V/3A on the side.

Ross,
5A  is for the total input into the AM5. The AM5 uses .6 amp when tracking and 1.3 amp when slewing.  The three amp port on the saddle is what’s available after the AM5 uses it’s draw.

 I use the AM5 mount as my portable rig with an 8 inch Edge. So I am always nearby when using this rig and the Wi-Fi is very appropriate. On my permanent system at home I have a 14 inch Edge with an ASIAIR mounted on the pier of my CEM 120. I have ethernet connected directly to the ASIAIR and then route all the controlling power and signals up through the CEM 120.  I THEN RUN EVERYTHING WITH MY IPAD IN FRONT OF THE FIREPLACE WITH A MARGARITA IN HAND.

I wouldn't give up the dual 23" monitors in my office for any iPad ever made when it comes to imaging.  I've been using a dual screen setup here at home and at the observatory and I dearly miss it when I'm nomadic and just have the 15" of screen real estate on my ancient laptop.

My nomadic system is a Hobym 170HD which I'm going to find a home for at the observatory. It's so tiny that I can fit in one more pier with some re-arranging I think. We have a 22x22 space right now with 5 systems running.

I'm really stoked about the new AM5 as the one thing I hate about the Hobym is no cable management. Each time I use it, I seem to end up with slightly different cable routing. While so far no snags, I worry every time I use it.

One of the beauties of this hobby is the diversity of reasonable configurations given the diversity of use cases.
