Hi! I get an error when I try to load your process icons, the one missing is NarrowbandNormalization. Can you point me to the repository if possible?

Hi Luke, I would be honored if you would take a look to my cheap DIY harmonic equatorial mount!

Hey mate - Nice overview pal. I wouldn't mine one of these if I did a bit more travel with my gear, but Im toooo lazy 😂 the Heq5Pro is pretty solid for now.

Great video as always! Going to try it on my first narrowband capture ever of the Eagle nebula! I was doing some testing and didn’t expect to be able to capture any data just seeing if I could get focus and stuff like that. I didn’t even polar align. Somehow my guiding was 0.7 arcsec so I just picked a target from the sky atlas in NINA and left it overnight. Using L-ultimate and 4 min subs I got 3 hours of data. I was shocked to see the images! Never seen that many stars before since I was doing broadband from Bortle 8/9 skies.

What is USBC port for?

Amazing! Thanks

Great video but I believe your trial parameters are misleading. In the terrestrial trial, you use an identical focal length whereas in your astro-trial you compare the RASA11 with a FL of 620mm with the Askar120 with a FL of 840mm. The difference comes into play when you look at the light you received from the same object In addition, the RASA has a central obstruction that takes away 16% of your light compared to the Askar. Both parameters downplay the difference in focal ratio.

Great experiment. I believe that AI, high resolution cameras and tools like PixInsight have changed astrophotography. Luke what do you think is the ideal refractor size for planetary imaging? I've been thinking a 150mm Sky Watcher on a EQ6R Pro mount

Welcome to sleep deprivation and good bye to nighttime activities.

Great review Luko! hope the price is not so high as the old one…

ZWO really listens to their customers and I can see nice improvements here. Curious is the new case allows the mount to be placed back inside without having to adjust the altitude (latitude). The soft case is great that way. Unlike my HEQ5 styrofoam boxes, the old AM5 case allows replacing the mount without adjustment. I do note the new color is more red and a bit less orange.

This model is supposed to be twice as accurate as the old one… we’ll see.

Also I don’t see the bubble levels, but i never use them, and it never affected my accuracy

Can you or should you move altitude bar when the sides are locked?

Hi Luke great video as always i like the new through cable addition so much better

If you wanted to experimentally test the effect of f-ratio, then it is completely nonsensical to add yet ANOTHER variable by changing camera. f-ratio is NORMALISED to aperture, so aperture has absolutely nothing to do with the argument. How you can say that f-ratio is not a very useful indicator of speed itself when f-ratio is used synonymously with speed is totally beyond me. I have imaged with an f#2 Hyperstar and f#4.5 Sky90 using THE SAME imaging camera for over 20 years and the resulting images are very clear in showing that the Hyperstar is indeed 5 times faster than the Sky90 - exactly as we would expect.

Really helped. Now i need to implement

Will the am3 have a similar revision?

Hmmm... I've been using 0.5 seconds guide exposure on my, now, not so new AM5 and guiding in the range between 3.8 and 6 arc seconds with both my petzval 71mm and my 102mm F7. I have considered trying .25 seconds, but wonder if your 0.02 may be at the point of diminishing returns. At least with my ASI mini 120, I doubt it could resolve much at that short exposure. In any case, shorter guide exposures are the key to better guiding on the strain wave mounts. I would be interested in knowing what guide exposures others are using....

My AM5 started to slip when my payload was nearly 13 kg. A substantial portion of the weight was above my Askar 120 APO in the form of a guider, Eagle, and associated hardware. I ended up using a counterweight and all is well. From my experience, the payload torque is more important than the payload weight. I wonder at what distance above the mount they are basing their payload weight limits.

Interesting video. I’m considering replacing my old HEQ5 pro with an AM5, just for ease of shifting it in an out of the garage and the lower periodic error. I was wondering what tripod you use for your AM5?

That was pretty damn interesting and some of the comments have also been pretty epic. I'm really enjoying this new style of work you are putting out. Love it. PS Congrats on the happy news! That's epic as well! x

This is my next big purchase.

these are the kind of the videos that make sense. Point out how OCD people are in this hobby and inform them there is a point of diminishing returns.

Excellent overview and it is still the best review couch on UA-cam.

F:2 is King. Collecting Photons Using an EdgeHD11 vs a RASA11 with the same camera is worlds apart. I ain't got no no time for no F:10/F:7 any more 😂 Compare your HD11 vs your RASA11.

Common AP, Paramount, 10 micron! It is time to produce this type of mount. Many people are waiting such mount from you.

Great! Ordered the N version yesterday. Curious about trying my C11 on it. I didn't with the original AM5. Where do you suggest attaching the ASIAIR? Although not recommended it worked great on the SIDE of the AM5.

Hi thanks for the great review. I have always wondered if there was a preferred method of placing the telescope in a saddle. I usually slide the dovetail from the front but I have seen people place the dovetail on one edge and then rotate it into the saddle. Is one better than the other?

10:45, that is the main upgrade I'm jealous of. I love my AM5, but its most annoying trait is that adjustment piece hanging low and knocking the tripod locking mechanism.

Thank you for the full review But be careful not to install the screws without the base on the side of the old mount, as they will damage the engine. See instruction booklet.

Where does the increased payload capacity come from?. Where is the mechanical improvement ?

Thanks again Luke! Good on ZWO for improving the drive accuracy. I fear that the other main change deflects from the real issue (too low power output) and will just hoodwink more newcomers into having unreasonable expectations. Attaching an AsiAir a main camera and dewstraps through this output will seem like a perfectly reasonable thing to do. It will inevitably lead to poblems and disappointment (whereas thrilling the customer should be the goal). I'm not looking for a dark cloud, but I upgraded my old AM5 with a Pegasus power saddle. Doing this with the new model will likely leave you without a usable case. Cutting the foam to allow room for puck (5mm higher up saddle) and the bigger knobs looks less likely to work with the new case. Also the 3A output is fine for the lighter equipment on the OTA, but powering a main camera (eg a 2600 MC) through this would require the full 3A supply leaving nothing for dewstraps and asiair with its other accessories. To my mind the rerouting change is NOT a power or cable management solution, its is just a nod to acknowledge a weakness that has been 'improved'... OR HAS IT?? There is a mismatch between the AM5 user manual and the scribing on the output port. I'm assuming that there's always been only 3A available (and the 5A as claimed in the user manual is a saleslman's typo). 3A is not enough to allow worse case (robust) power distribution into the rig design. So if you want FULLY effective cable management power and dew control, swapping to a Pegasus powersaddle will do that, but this route now has extra downsides compared with the older AM5 model. Now it leaves you (potentially) without a usable case, and the new AM5 cables will need to be cut or disconnected and stowed where they wont jam the RA movement, or short out.😪

This looks tempting, for replacing my EQ6R that is. I must however say that I'm kind of disappointed to see that the through the mount USB is 2.0...

Great review Luke. I'd be annoyed at the mark on the casing caused by the Allen key too! I won't be buying one at the moment as I'm quite satisfied with my AZ-EQ GT. Clear skies!

I think the opening frame/thumbnail of this video is misleading and too much click-bait. There is nothing mythical about f-ratio, it is physics. And when towards the end of the video you start about reducers and not believing how they are in fact speeding up imaging, I feel you missed the mark. Sure, at fixed image scale it might be so. The fact that in your experiment you change BOTH the focal length AND the camera (pixel size) already shows you are doing a particular experiment. But for most people starting their astrophotography journey, it should be clearly stated that when changing the focal length for a fixed aperture and hence the focal ratio, one indeed gathers more light per unit time, at the expense of imaging resolution. The light cone is steepened, meaning the light is not spread out as much on the sensor and hence the light hitting the same surface area on the chip per second is increased, but with less resolution. Maybe you can consider changing this thumbnail? "When imaging at fixed resolution, it is not the F-ratio that determines light gathering power, but the aperture" would be much more to the point.

Great review Luke looks like some very nice updates , do you think this would be able to handle a Quattro 250 if it was mounted on a permanent mount?

An F on the new carry case. Trading in that nice older one for a 6-pack cooler is not good. And not sure how you now lock down azimuth with going underneath with a wrench, the old lock handles seemed to work OK. Would have to try it all for myself at night for a true measure :). Thanks Luke!

Hey luke, thx for this overview ! It seems that there is no longer a bubble level... ZWO has placed these bubbles elsewhere on the new AM5?

It shows they are listening to reviews of pros an cons and thriving to make things even better, nice info Luke and look forward to see what you think of this red devil... But we want an AM7/AM8 👀

I'm hoping one you will test this mount with at least a 8" SCT at at focal length of 1280mm and greater using an OAG for guiding. With the improvement in PE I'm hoping the guidance from ZWO changes about suggested focal lengths. I didn't want to take a chance on buying a strain wave mount if it wasn't suitable to guide my C8 SCT. In your opinion should this new version open up higher focal lengths?

Oh man ZWO is going after all of the other mount companies business for this weight class! This is now the perfect mount! Thanks for video Luke!

Hi Luke, Well, you got my mouth watering for a new mount now. That new AM5N is VERY enticing. Hard to believe it can handle the Celestron Edge HD 11". I sure would like to give it a try though. Clear Skies

$4200 AUD with tripod yeah nah there is no competition at all seriously disappointed with ZWO

I replaced my AM3 saddle with the Pegasus 10 amp one. It powers everything. The mount, the ASIAIR, the camera etc. 3amps is insufficient. Is this new saddle on the AM5 removeable so I can replace it with the Pegasus? If not, I will use the Pegasus Power box to power everything. I'll just Velcro it to the front of the mount!

Great intial review Luke. I will probably be buying an SWG mount sometime between now and New Year and an AM 5 is one of the units I am considering. First, do you know if there is any difference in the price point between the two models? Second, do you happen to know when the new mount will be released here in the UK? I do like the look of this mount, but to be honest I quite like the look of the Sky Watcher SWG mount that comes with dual saddles ( think it's the 100 ) as well but I have no idea when that will be available either. If it turns out that they are both out of my price range, then I'll probably go for an AM 3 or the original AM 5 if there's any left. Clear skies.

Great review! Looks like some worthwhile improvements. I just got the older model so I'll wait on upgrading...

Is the old model going to get a price reduction?
