As someone who has been learning to take astro photographs this was one of the best and most straightforward Astro photography KZbin video tutorials I've watched over the last couple of years. Thank you for a short, and using a pun, very focused presentation which has helped me tremendously.

Any hack for the 32gig SD card limit on the Air+?

Thanks lot... dear friend , can i use canon M50 mirrolus camara

Thanks for this! Very helpful indeed. Especially when you're first total score is 1400 and the benchmark takes forever -.- I reduced my swap directories from 4 to 2... Got 6078 though! :o

Can I control it using a mobile app? I need portability

I could not figure out why my flats were never what my stacking program wanted! I did not know that you had to keep track of the focuser numbers! Thank you! So many times I feel like I am searching for needles in a haystack while learning this stuff.

Great video, loads of information! I see that you are using many different softwares. The software for the MT 3000 should ne enough to get the job done correct? Please let me know, thanks.

your camera is to of control. it won't keep focus and it won't keep exposure. I always just keep it all in full manual.

iOptron doesn't manufacturer their telescopes either.

I've been looking for a replacement for my AVX mount which carries my C8 SCT. With my image train it's about 19lbs. The image train consists of Starizona focal reducer, Celestron OAG, ASI174MM Pro, guide camera , ZWO filter drawer and ASI071MC Pro, I looked at you logs and while the guiding results were good for your refractor the couple for your C8 where well over 1" . I'm thinking strain wave mount are not suitable for anyone over 1000mm due to the PE. I'm thinking I'm going to have to look at a CEM40 instead.

So happy I found this video. What USB cable were you using the USB 3 or 2 to hook up the camera to the ASIAir? I note there are two different USB options on the ASIAir. Thank you.

When you spin your telescope around like that, I hope you realize there is just a bundle of thin wires that goes up to that head. And every 360 rotation puts another another twist into that bundle of wire. And if you have a tendency to rotate that scope in the same direction you'll eventually break the wires inside the mount.

Unboxing? What else is in the box?

For me the EQstar was a nightmare to setup. Took me like 2 weeks to properly get setup due to a bajillion different problems. Had to calculate my own gear ratios and do more math since I counted wrong. Had to find cable converters which I ended up just making one myself by soldering the wires together. Had software issues due to the confusing instructions, but it was worth it. Now I can find targets extremely fast using sharpcap. I can use autoguiding but haven’t got around to that yet. The only issue is that for some reason lunar tracking is very odd and the mount sorta forgets where it is when trying to do an automatic moon mosaic, but that’s not rly an issue for me. Overall worth, and if anyone has questions bout the EQstar I might know the answer since I went thru every single problem possible

Do you need to balance the dec as it has a clutch?

I gave it my best, but doesn't seem to run anymore. Can it be due to the upgrade from Stellarmate to a newer Pi-kernel?

Thanks a lot. I have gem28, other router, all done well, almost work, I see my mount, asiair too on my router but how to setup mount on asiair. this one is some problem for me. with usb mount works, when I disconnect gem28 from the asiair it stops working. How to setup asiair, ethernet/serial?

Nice - this is one of the reasons I love both my CEM mounts. I learned earlier today that the strainwave drive used in the AM5 is the same used in the HEM27 - they come from the same 3rd party manufacturer. I need to replace the lubricant on my CEM26 - it has the stock factory applied lube and it has now gone bad - humidity and cold did it in. But my CEM40 is giving me around 0.45" rms guided without issue, out of the box.

I’m disappointed the Guidescope wasn’t red! That’s really bad for my OCD

is there any reason you wouldn't want to enable all four ports?

Joey - Do you know how to control the speed of the hand controller ? I find it is way too slow. Thank you

Def not a lie.. 2nd week into my AM5 shooting flats in my living room.. I fell asleep on my couch as it was happening and frgot to turn off m-flip.... I wake up to the sounds of CHHChkckkckKKSKKSKKSKKkkkk... Yep cables got snagged. Power jack broke off halfway into the AM5. Luckily it was only 150 to have repaired.. regardless ended up picking up the HAE69CEC... Bye bye AM5. lol.

Zo the AM5 has way better polar alignment knobs (on the iOptron you need an small wrench, that you drop and never find and when it’s cold good luck), you polar align the AM5 with ASIAIR in minutes. But more importantly the guiding analyzes done by another reviewer show that the AM5 is quicker and more accurate than the iOptron … Yeah the power thing could be better, but if you are a pro that is not really an issue, we had cable spaghetti for years, so one cable is not that hard to manage (ps when you showed your power connector, that 12v cigarette connector, really??!!). If I’m informed correctly the DEC of the iOptron is traditionally geared ??!! So old tech on the Worm + belt … that will be interesting how that will hold up, and also explains the slower / more spiky behaviour in corrections.

Hi Joey, thank you very much ¿ Can use it with AsiAir mini?

Is this video a joke? How can you compare two mounts without showing actual tracking and guiding performance? I can only assume that you haven't used a ZWO mount (since other reviewers routinely report that the AM5 performance is superior. But, naturally, a mount that uses a ring-and-worm drive for the DEC axis must be better. Oh, and by the way, explain how the iOptron arrangement for changing from Vixen to Losmandy bars is something you would want to praise.

Have you helped anyone figure out how to best image the April total eclipse with a Sony camera body, an ASIair and an AM5 or 3?

Thank you for posting.

Do you live any where near Dallas?

Strange guy!

So how will hem 15 compare?

Are there telescopes really not there’s? What about the pending patent that they mention on there website, could be that of Askar patent instead of zwo?

I will call it as I see it.. no issue with power ports on AM5 I run it up ASI AIR. Works for me no issue. I like how it all connects with ZWO eco system. plug and play simple to set up and use.. A friend of mine has HE27 and he is happy with his. I dont see either as deal breaker. thats all I got to say..

that's not a comparaison.... that only because you bought an ioption.... make comparaison A to Z before saying this one is better than an am5 (including guiding etc...). futher more, you just give a poor image of your chanel and capabilities with this.

Did you experience spike issues with guiding with your setup

The title would more properly be, “iOptron HEM27 is better (for me) than AM5”

Hello!. Excuse my English😢😢😢. I want to buy the ioptron HEA29. I have a zwo asiair. How have you made the Asiair work well with the mount? Thank you very much 😊.

Those 3 points aren't an issue for me, but I guess the rear cable mounting would be the nicest as far as the power cable goes and make things a little tidier. But definitely not a deal breaker as it is for yourself. And all my power connections come from the power supply direct, nothing goes through some other device.

Please buy a microphone, or use a Phone with Irium Webcam.

Is there a simple way to only change the config file and disable wifi (and bluetooth if it has it) on the ASIAir? Something like dtoverlay=disable-wifi or dtoverlay=disable-bt? I am using the Mini btw, with the Rockchip board, I believe, not the Pi. Thanks

Hey Joey, thanks for sharing this. I am able to use the use cable to do the connection plus shooting! guess it's the new firmware? anyway, thanks for this!

Awesome!! I'm trying to figure this out for my HEM27. From the PlusRoc 12V/24V to 5V Converter what to wires do you solder for the DC connection to the Plus and the USB C to the router?

any work arounds on the new asiair plus 3.3 version yet

Glad to know you are having success using the 3A power connection of the HEM27, but I find it to be a limiting factor in my setup and don't use it. To start, I'm not a fan of the ASI Air, preferring NINA, and I don't trust 3A to cover the camera (when cooling) plus dew heaters plus a computer. I also wish they used USB3 instead of USB2 in the saddle, as perhaps that would've allowed me to take advantage of that cable bypass. As a consequence, I use a Pegasus power box and end up dangling the cables (power and USB) off the back end. It works, and I'm happy with the tracking performance (which is somewhere in the neighborhood of .5, but I don't document that; if my stars are round and tight, and they are, then all's good whatever that number is). Overall, I'm happy with the HEM27, as it's super easy to set-up and just works (it carries an Askar FRA300). Alternately, for my larger scope, I've always fought with my G-11, finally giving up on it and replacing it with an iOptron HAE43 (ironically, its cabling is off the front, and while it has a 'through-the-mount' option, it doesn't really fit two cables, strangely, so I also have to dangle off the back). It seems there is never a perfect mount, short of spending $15k on a Mach2, which isn't going to happen. Clear skies!

Interesting. Does this allow adding non-Zwo cameras and accessories? I know that default is that only Zwo astro cams (plus some DSLRs) will work with it.

very good comparison. I enjoyed it, please let me know what is your proof which am5 is made by ioptron.

I thought you were going to say it tracks better than the AM5 which is mounts true value to me. My am5 normally tracks between .25-.5 with a 25lbs load without a counterweight, how does your track? Nevertheless, It depends on the needs of the individuals power requirements because the iOptron nor the am5 could never power my whole setup. Your friend probably had poor cable management which probably caused his accident. It's nice that your mount could spin like that but unrealistic unless you forgot one day and let it track all day but am5 can set limits to its range of motion to prevent full spins like that. Thanks for your opinion.

Ok, it's not a video about computer parts

nice vid! Is 3 amps on the output of the mount enough to power all that up top? What about guiding if you don't own a Dou? How do you connect to the ASIAIR without using the usb from the hand controller the ASIAIR? sorry for all the questions... just got a hem 27.
