How much can the ZWO AM7 carry?

20 kg without a counterweight and 30 kg with one, from a 6.75 kg head. My C11 EdgeHD rig of almost 14 kg sat at 70% of the no-counterweight rating.

How well does the AM7 guide?

The ASIAIR readout across the 18 minutes of that M 51 test averaged 0.58 arcsec total RMS (0.40 in RA, 0.41 in Dec), between 0.35 and 1.17, with just over 10 kg on the mount and no counterweight. With the C11 EdgeHD the guide sensor in the camera struggled at the long focal length.

Does the AM7 come with a counterweight?

The bar in the box is 25 mm across and 250 mm long; no weights come with it.

Should I buy the AM7 or the AM5N?

For a rig over 15 kg, the AM7: the AM5N stops at 15 kg without a counterweight. Below about 12 kg the AM5N does the same job for less and weighs 1.25 kg less.

How does the AM7 compare with the MLAstro SAL-33 and the ClearSky ST25?

The SAL-33 carries 15 kg, 20 kg with a counterweight, at about half the price; the ClearSky ST25 matches the AM7 at 20 kg and 30 kg and won my seven-mount showdown. The AM7 slews fastest and is the one that runs in the ZWO app and the ASIAIR.

Rank: #10 of 18 mounts
Verdict: With reservations

Written by Damon Scotting 7 min read

Buy it if

Your rig weighs 10 to 20 kg and you would rather image without counterweights.
You run an ASIAIR and ZWO cameras and want the mount in the same app.
You slew a lot, for live views or for steering by hand after satellites.

Skip it if

Your rig is under about 12 kg: the ZWO AM5N carries 15 kg for less.
Value comes first: the MLAstro SAL-33 carries 15 kg for about half the price.
You often need counterweights: its thick bar takes weights with larger holes.

“My first thoughts and feelings towards the AM7 mount are it's really good. It is worth the money that you pay for it.”

How well does it guide?

My ASIAIR guiding readout on M 51: 18 minutes of 1 s guiding, just over 10 kg on the mount and no counterweight

“The payload now is just over 10 kg. There is no counterweight being used at all, but this puts it at about 50% of the recommended payload without a counterweight, and it's doing a pretty impressive job.”

“When imaging in narrowband using the C11 EdgeHD telescope, it's such a large focal length that the guiding camera really suffers.”

What is it for? In my words

Four things the AM7 is for, in my words

Power and USB-C on the dovetail

They've also been positioned closer to the edge, making them more accessible than ever before.

Guiding through the camera's own sensor

The key thing to note here is that I'm not using a separate guide scope and camera. I'm using the ASI2600MM Air, which comes with an inbuilt guiding sensor.

The handset

I remember when I first saw this Joy-Con appear on the first ZWO AM5 mount and I really wasn't too sure what to think of it. But I love it.

A C11 without a counterweight

Have you ever seen such a tiny mount handle a big telescope like this so flawlessly? I think the AM7 mount actually makes the telescope itself look deceptively lightweight. It's not.

0:00 Out with the old, in with the new

0:02 Out with the old and in with the new. 0:02 Now, would you look at this? 0:02 Have you ever seen such a tiny mount handle a big telescope like this so flawlessly? 0:08 Something about this just looks so unnatural. 0:09 In fact, I think the AM7 mount actually makes the telescope itself look deceptively lightweight. 0:15 It's not. 0:15 In fact, the payload is almost 14 kg in total, which is conveniently 70% of the max recommended payload for this mount without a counterweight. 0:22 So, right in the sweet spot. 0:24 I wanted to have a play around with this mount before tonight's observing because it does look as though it defies physics. 0:30 The mount arrived in its own little carry foam case with the required data cables, remote control, and a chunky counterweight bar.

0:30 What you get in the box (no tripod, no power supply)

0:35 But, much like its predecessors, you do need to purchase your own 12 V 5 A power supply to get it going. 0:41 And as is the case with most mounts these days, it does not come with a tripod. 0:45 So, you're going to have to buy one that's capable of handling this payload or build your own pier mount like I've done here. 0:50 I have actually just made another one, so I promise I'll be sharing with you a video very soon about how I made it and how you can make one yourself. 0:56 Right, so maybe it's the fact that we have clear skies here in the UK for the first week this year, but I have a really good feeling about this mount. 1:03 I'm Damon Scotting, and this is Astronomical.

1:07 First impressions, building the rig

1:07 All right, so first impression, that is very sleek. 1:09 This is a solid design. 1:09 It does exactly what you pay for it to do. 1:14 It is a very capable mount. 1:14 So, yeah, I think I'm only missing one cable before this is fully functional and up and running, and that is just a power cable to go from the back end of the mount just here into the camera to give that some power. 1:24 So, I'm just going to explain a little bit more about what else I'm using with the mount just here. 1:29 So, of course, we have the Celestron 11-in EdgeHD telescope.

1:29 The full back end: C11 EdgeHD, reducer, filter wheel and ASI2600MM Air

1:30 It is a beast. 1:33 But, down the back end over here, I'm going to spin it around. 1:35 Connected to the telescope, we have a 0.7 times reducer as well as a T-adapter, camera angle adjuster from ZWO as well, as well as a 7 by 2-in filter wheel, and then the ASI2600MM Air camera. 1:46 So, with this setup, I'm hoping to take some really nice quality narrow band images of our night sky at a very long focal length. 1:56 Just for entertainment purposes, here are a few images I captured with the C11 EdgeHD.

1:59 Why I had to switch to the Askar SQA106

1:59 But the truth is, for the rest of the video, I'm using the exact same camera setup at the back end, but now with a much sharper telescope in the Askar SQA106. 2:09 And this is for the simple reason that I was really struggling to guide with the C11 EdgeHD. 2:12 So, I think the next question I'm going to answer is how well does this mount guide, and is it the best value mount on the market currently available?

2:20 The M 51 guiding test, 20 minutes of 1 s exposures

2:20 So, the key thing to note here is that I'm not using a separate guide scope and camera. 2:23 I'm using the ASI2600MM Air, which comes with an inbuilt guiding sensor. 2:28 So, the issue is when imaging in narrow band using the C11 EdgeHD telescope, it's such a large focal length that the guiding camera really suffers. 2:36 So, instead, here is almost 20 minutes worth of 1 second guiding whilst tracking the Whirlpool Galaxy with the Askar SQA106. 2:45 And as you can see, these are some very healthy numbers. 2:47 So, the payload now is just over 10 kg. 2:49 There is no counterweight being used at all, but this puts it at about 50% of the recommended payload without a counterweight, and it's doing a pretty impressive job.

2:57 AM7 specs: 6.75 kg, 300:1 reduction, 20 kg payload

2:57 The AM7 strain wave mount uses a 300 to 1 reduction ratio drive, which makes it a premium level mount. 3:04 With a total weight of 6.75 kg, it still falls into the category of what one would call a portable mount, especially since older mounts required multiple 5 kg counterweights as an absolute necessity to operate.

3:14 The AM5 is officially obsolete (and why)

3:14 I generally think it leaves the AM5 mount in the dirt. 3:18 There's no real need for it now since for just 10% more cost, you can get a significantly better mount that only weighs an extra 20%, but it can carry significantly more. 3:27 I do, however, still have a soft spot for the tiny AM3 mount, so I'd continue to advocate for that.

3:32 The thick counterweight bar problem

3:32 There is a small hiccup with the AM7 counterweight bar since it has a much larger thickness than a typical counterweight bar, meaning you've now got to go and find some specific counterweights with larger holes, and some websites are charging ridiculous prices for these. 3:44 At this point, you'd be better off just taping water bottles to the end or buying actual workout weights and custom fitting them yourself. 3:51 But then I suppose if you've got two and a half thousand dollars to drop on a mount, you expect it to be able to pay a couple hundred more for a custom counterweight. 3:59 The power port and USB-C ports at the back end of the dovetail continue to be a welcome addition. 4:02 They've also been positioned closer to the edge making them more accessible than ever before.

4:07 New competition: MLAstro SAL-66 and Prometheus Astro

4:07 So, to tell you the absolute truth, when I first got word come through from ZWO saying, "Hey, do you want to review this mount?" 4:13 my immediate thought upon seeing the specifications was, "That's pretty underwhelming." 4:18 And that might sound pretty harsh considering 20 kg without a counterweight is incredibly impressive. 4:24 We haven't really seen anything like that on the main market yet. 4:25 But the reason I had that immediate feeling was I just got off the back of reviewing another mount which is just to the left of me right here, and it is the MLAstro SAL-33. 4:34 And that's capable of 15 kg without a counterweight, 20 kg with a counterweight. 4:38 So, not as much as this, but upon releasing my review, the owner just announced that he was going to release another mount called the MLAstro SAL-66 which had some very impressive payload capabilities. 4:56 And again, its payloads are huge. 4:57 So, all of a sudden I've gone from being, "Yeah, 20 kg without a counterweight would be insane right now." 5:04 to, "Come on, ZWO, surely you can do better than that." 5:06 It's great. 5:07 20 kg, 30 kg, fantastic. 5:07 But I think it's because now all of a sudden we're seeing this flurry of new mount manufacturers coming out with very impressive mounts for fractions of the price of what ZWO are charging. 5:18 So, let's start off by doing a deep dive into the specifications of this new mount and seeing how it compares to the other competition on the market, as well as those third-party mounts that we're not too sure if we can trust yet, but do offer a very good bargain. 5:30 The MLAstro SAL-66 is an eagerly awaited design that incorporates robotic polar alignment for the first time in a mount. 5:37 This looks set to be a staple for mounts going forward. 5:41 That in itself is enough of a gimmick to make it worth buying. 5:43 But even more so when it has these astonishing payloads and promises to go toe-to-toe with the AM7 in terms of prices. 5:50 Meanwhile, Prometheus Astro are adding a multi-power output system in the mount head, something I looked at with the ClearSky ST25 mount and came to the conclusion that it's very handy and a nice simple addition that again makes astrophotography easier, which should be the ultimate goal of all of these mounts. 6:06 Yeah, I'll leave it up to you to decide in the comments which of these mounts you think looks the most appealing in terms of value for money.

6:13 Final verdict, who is the AM7 for?

6:13 All right, there we go. 6:13 So, in conclusion, my first thoughts and feelings towards the AM7 mount are it's really good. 6:19 It is worth the money that you pay for it. 6:20 Is that an expensive price tag? 6:22 For me personally, I'd say yes, but then in relation to the rest of the gear that you're buying in your entire astrophotography setup, it is not out of place. 6:29 When I did that really big mount comparison video last year, the most obvious thing to note in terms of differences between the ZWO AM mounts versus all of the other third-party mounts was that this mount is very quick. 6:41 It literally zips between the targets. 6:43 It's the fastest one by far. 6:45 So, yeah, get used to seeing this because I am going to be using it a lot more in the future, especially when I'm hoping to do some more live streams over the coming months. 6:52 This is going to be my first choice because when I put the Sky-Watcher HAC125DX on a telescope mount, I want to put it on something that's really fast and can zip between stuff.

7:02 The Joy-Con, best mount remote ever made?

7:02 And if I do see satellites or something like that, I want to be able to just pick up a Joy-Con controller like this, which is unique to just this telescope mount, and then just follow it. 7:14 And it can definitely keep up and I don't have to worry too much about it falling off balance or any slips. 7:17 I mean, that's really cool, isn't it? 7:20 I remember when I first saw this Joy-Con appear on the first ZWO AM5 mount and I really wasn't too sure what to think of it. 7:27 I actually thought it looked quite tacky, um but I love it. 7:30 This is the best remote control that I've ever used of anything. 7:32 Yes, it doesn't have a display on it so you can pick out targets, but ZWO have an incredible app that lets you pick out the targets alongside images of them anyway, so you can just download the app for the mount and then have a much better user experience than when you have these really tiny displays on the mount itself.

Pros

“The payload is almost 14 kg in total, which is conveniently 70% of the max recommended payload for this mount without a counterweight.”
“Here is almost 20 minutes worth of 1 second guiding whilst tracking the Whirlpool Galaxy with the Askar SQA106. And as you can see, these are some very healthy numbers.”
“It literally zips between the targets. It's the fastest one by far.”
“This is the best remote control that I've ever used of anything.”
“The power port and USB-C ports at the back end of the dovetail continue to be a welcome addition.”
“With a total weight of 6.75 kg, it still falls into the category of what one would call a portable mount.”

Cons

“There is a small hiccup with the AM7 counterweight bar since it has a much larger thickness than a typical counterweight bar, meaning you've now got to go and find some specific counterweights with larger holes.”
“You do need to purchase your own 12 V 5 A power supply to get it going. And as is the case with most mounts these days, it does not come with a tripod.”
“We're seeing this flurry of new mount manufacturers coming out with very impressive mounts for fractions of the price of what ZWO are charging.”

Is that an expensive price tag? For me personally, I'd say yes, but then in relation to the rest of the gear that you're buying in your entire astrophotography setup, it is not out of place.

Who the AM7 is for

Complete beginner

Skip

A £2,599 head for 20 kg of telescope is far beyond a first rig; a TeSeek 11 or JUWEI-14 is where I would start.

C11 or big refractor owner

Buy

It carried my C11 EdgeHD rig of almost 14 kg without a counterweight, and the Askar SQA130 through 12 and a half hours on the Elephant's Trunk Nebula.

ASIAIR user outgrowing an AM5N

Buy

It carries 5 kg more than the AM5N without a counterweight from a head only 1.25 kg heavier, in the same app.

Value-first buyer

Skip

The MLAstro SAL-33 carries 15 kg, 20 kg with a counterweight, for about half the price.

Live-streamer or satellite chaser

Buy

Of the mounts in my comparisons it slews fastest by far, and the Joy-Con style handset lets you steer it by hand.

Small refractor imager

Skip

Under 10 kg the AM5N or a TeSeek 17 does the same job for less money and less weight.
