That's a great review! I'm running an almost identical rig - an Orion EON 130 APO (27lbs) on AM5 + PE200 with no counterweight. I love it now, but my immediate first impression was a terrible disappointment! A really bad high frequency vibration was introduced when I moved this OTA over from my massive EQ6 to the AM5 (configured as yours on the TC40 tripod but initially with the counterweight present). The inertial mass of the EQ6 mount head (17kg) and tripod (7kg) acts as a damping reservoir to absorb any trilling that could set up in the OTA (from touching the focusser, wind gusts etc.) and I think the dynamic behaviour of the counterweight with that weak anchor point on a thin plate contributed to the problem. On the EQ6 I was used to a very mild 2-3 Hz vibe that died down pretty much instantly (within about a second after a disturbance), but with the AM5 + TC40 combination these became quite vicious 5-10Hz and lasted about three seconds creating little saturn like star images on the first short exposure. This made PA and hand focusing very tedious and unpleasant experiences (take two shots, throw one away). I spent months on this, and have now taken steps (lots of measures) to manage that problem. It is now at an acceptable level though I still reserve the right to be fussy and grumble about it. So for that reason I can't agree with what you were saying about the AM5 being a windproof mount. You are right about strainwave drives not suffering wind against backlash, but there are often other sources movement (flex). My current AM5 setup uses a losmandy dovetail, no counterweight, and is back on the EQ6 tripod + PE200 with the legs extended to give it a good wide stance. Even with these measures in place it is *still* a lot more sensitive to the wind than the EQ6 ever was. Don't get me wrong. The EQ6 typically guides at 1"-2" and the AM5 figures are 0.5"-1.0" - so even on a gusty night the AM5 is never worse than the EQ6. But so it should be at twice the price. I get it that not everybody necessarily has this same experience, but it happens. Clear skies everybody!

Interesting to hear that even a big iOptron acts up now and then to ruin some subs. I’ve had 100% success with the AM5 as well. But that’s almost always true of my Astro-Physics mounts, too. But I agree that the traditional mount makers have blinkers on if they think strain wave mounts aren’t the future, certainly for any mount designed to be portable. There’s little point in designing mounts you don’t need to guide, which had been the Holy Grail of mount design. An autoguider costs a lot less than some super machined worm and wheel gear set, and as you say, has the benefit of dithering. Thanks for the review! Clear skies. Love the fireflies!

Great informative video! Thank you. One question. I’ve had my AM5 for a few months now and truly love it, however, when doing a PA I find that loosing and then tightening the mount adjustments always throws off the PA and I need to redo…and redo. I’ve wondered if keeping some tension on the mount adjustments rather than completely loose…or is it possible to keep significant resistance on the adjustments without damaging the mount??? Any thoughts on this would be most helpful. Keep up the great videos…they are unique.

If it's thrown off a lot when you tighten things it means something is radically off balance. Try to find the center of balance for you scope tube and move it to that spot like I showed in the short clip. For tension I do always leave just a little tension on it. It will not hurt the mount they are designed to be friction points anyway.

Just got this mount a few weeks ago but haven't had a chance to use it with all the wildfire smoke. But just heard some nice tips I didn't know like the Dec axis can be turned.

Sure are. I am in the country where there are fewer lights so they are still around here. IN the city they have virtually gone extinct because of lights.

The reason you need guiding to dither is because the way the software is written, not anything to do with the hardware. (As far as the mount is concerned, it just receives a command to nudge it in a particular direction; it doesn't matter if the vector is calculated based on the guide scope or the imaging scope.) Paramounts, for example, can dither unguided. What is needed is zero period error (after correction) and a robust pointing model that takes into account things like flexure of the system. Currently, this is only available on high-end mounts like the Paramounts, but I suspect that in a few years the more mid-range systems will allow for this.

I don't know if others have pointed this out but you don't need guiding to dither. You can quite easily dither without guiding. Typically to run unguided you need a mount model that makes micro corrections in real time and that probably can't be done with this because it's error is not periodic, at least over short time scales so guiding is essential with a mount like this but that statement does not generalize to all types of mounts.

@@magedsyehia That should not be over the weight limit. How close do you get your polar alignment? Check for something loose. Sometimes it's the darndest things that come loose. You could also try stretching your gears a little. Unload the mount of everything and have the head rotate around a bunch of times. Will get the gears to lap themselves in. If noise increase then something mightn't have been assembled correctly inside.

Make sure your triopod is sitting on solid ground and not grass. I cut three plywood squares that the tripod sits one when it isn't on bare dirt or pavement. I use the all sky polar alignment option with my ASI AIR Plus and it gets aligned quickly and accurately.

AM5 is great ... until it isn't. Then you will face the horror of ZWO Tech Support. My brand new AM5 failed at -11C ambient and 8.62kg of payload -- both well within stated specs. RA stalled during an attempted Meridian Flip. Now it has been sitting in ZWO Tech Support in New Jersey since December 6, 2023. Every time I contact them, I get the same reply: "Sorry. It will be ready next week." Does "next week" mean something different in New Jersey?

ioptron HAE 29 is better for the same price. It is something forgotten in this video. Please compare the same technology to be fair. We know the very good choice for a small but strong Goto mount like AM5 thanks to the robotic technology. It is a must for air travel too. My C8 tube and my Strainewave mount are good for international flight as hand luggage because less than 10 kg. No risk to suffer of bad care in the airport, their size are good to stay nicely above my head during the flight. The only true issue with this technology solution is the need of a computer brain to deal with the Error periodic which is 10 times and more higher than a very good classical Equatorial goto mount with backlash and 25 kg extra weight. Once the brain is connecting to the mount the mount free of backlash is becoming a precise mount without any problem up to 1 m focal instrument for deep sky imaging. The better solution with a extra cost is the Ioptron EC strainwave mount version sold for different loads, up to the C14 telescop. From this EC we get 0.1 arc/s precision or less. The baby AM5 is a good choice but the buyer must check to buy everything in ordrer to begin with. What a big step this new decade is offering for this lobby. I wish one day the AI will be suggesting me to organise the night and teach me during the exposures under its control about Astromony.

There is nothing personal or ridiculous about it. Most astronomers use red lights at night and so read hardware shows up well under it. I would prefer white but its a good compromise. Also with a red or white mount i can just glance outside to see what is going on. A black mount will be invisible. Also when doing daytime work black is not thermally stable and does all sorts of nasty things to tracking of the sun. So there. Some good scientific reasons ;) I touched a few at NEAF and the knobs for polar alignment were not as smooth. Seams like the joining structures are a little different. The design zwo went with is smoother and make polar alignment faster.

Have you ever seen an aircraft instrument panel illuminated in red? If there is one area where you have to "have the eye" at night, it is this one. All walkways of all recent military buildings are lit green.Why red?Contrary to popular belief, red light should be avoided, as the sensitivity of the eye is very inefficient for this tint. This makes it necessary to use relatively intense lighting to see details. The opposite effect of that hoped for!

Seems extremely optimistic compared to many that I know actually own it… It’s the opposite of wind proof, because it’s so light… a lot of what is said here is overstated clearly schilling to ZWO without having actually used it… no way it’s going to work with a 44lb long LF scope just ain’t happening… You are way wrong about tracking too, you’ll understand when you are more advanced as an astrophotographer. Astro-Physics knows a lot more than you do…

I'll be putting the newt back on here soon. It's a little above the 44lb limit. AstroPhysics disappointed me when I talked to them at NEAF. I asked them how they skiv their gear and they did not even know what that means. As a machinist from and from my conversation with them they outsource that to a machine shop. Scary if you ask me. They make some big stuff for sure and are the only option with some weight classes. I put that ending in there for them as I hope they do start doing better. Optimism is ok but experience is better. I can tell you backlash free mounts will always do better in the wind. They will punch way above their weight class.

@u2fletch

The physics are spot on regarding backlash in the wind. Whether the mount is light is irrelevant. The OTA is a sail. The longer it is the longer the moment arm and the resultant forces from wind gusts get bigger. As he stated in the review, the stiffness of the system is more important. Yes, once the system starts to flex, a heavier tripod will move more slowly. F=ma. But at this point either rig will lose the sub. Can you please elaborate on “way wrong about tracking”?

@@u2fletch Tracking is often used to avoid chasing seeing, with guiding you end up in a feedback loop with worse than atmospheric limitations, not being able to track is a serious limitation, tracking is superior to guiding for this reason. I somewhat agree and disagree with your physics, it’s not a simple harmonic oscillator so just adding mass doesn’t just effect it’s oscillation frequency, it adds rigidity with less flexure on top of a higher moment. I don’t think you could successfully model the behavior of the system in FEA with F=ma…. I have a mount that only has a little more mass but images in 40+ mph wind with zero subs tossed, so there is a massive difference…. These are a couple reasons why you’d invest $19,000 in a solid Astro-Physics or Software-Bisque mount… There are extremely numerous reports of very poor results with this mount in wind, so it’s a real problem and clearly wasn’t tested for the review, I believe it was actually sarcasm honestly stating that it’s less affected by wind….
