### 1/5 — Now installation not work on MACOS

*2026-08-21*

Impossible to install on my Mac mini M4.

### 5/5 — MacBook Pro

*2026-07-29*

Although it is an iPad application, I use it on a MacBook Pro M4. It runs perfectly with no issues so far. Seamless switch between inside use (MacBook) and outside use at the telescope (iPhone).“

### 3/5 — Pas mal !

*2026-06-07*

Comme tous les systèmes propriétaires, il y a les avantages et les inconvénients. Je fais de l'astronomie depuis l'âge de 6 ans et j'en ai plus de 50 ans aujourd'hui. Je suis chasseur d'éclipse solaire et toujours aussi motivé par notre espace de nuit. J'adore leurs caméras mais j'avoue qu'un peu plus d'ouverture sur les produits, asiair serait les bienvenue. j'adhère de la même façon aux produits Apple qui se sont ouverts, petit à petit tout en gardant une partie sécurité et stabilité qui permet de garder la fiabilité. Merci pour ce produit . Continuer.

### 3/5 — Gut aber…

*2026-05-28*

Die Funktionalität der App sowie die Integration der unterstützten  System ist gewohnt gut und erweitert sich ständig. Mit Bedauern stelle ich über die vergangenen Monate fest, dass die Systemstabilität immer mehr leidet. Warum bericht die Verbindung immer wieder ab, obwohl die Distanz zwischen den Geräten minimal ist. Es kann kann nicht an der Reichweitenbegrenzung liegen, wenn die Verbindung nach drei Belichtungseinheiten abbricht, obwohl der Empfänger (Handy oder IPad) sich innerhalb von 3 Metern befindet. Der Verbindungsaufbau ist teilweise mühsig und bedingt mindestens den Neustart der App, des WLans oder gar des Gerätes. Bitte bekommt das in Griff, sonst vergeht die Lust am Arbeiten mit ASIAir. Alternativen gibt es mittlerweile. vor etwa 4 Updates war die Stabilität besser. Implementiert am besten auch eine Fallback Option.

### 5/5 — Fantastic product that continues to set the standard

*2026-04-20, version 2.5.2*

I have been using the same pro-product for a number of years now, it is well thought out and continues to receive updates.

My one ask for improvement request is on the star-chart. Please consider having astronomical symbols for objects visible when zoomed out - maybe different colours. I found it a little difficult to scan the sky without conducting a text search.

Cheers

### 3/5 — If it ain’t broke…..

*2026-03-29*

Constantly introducing bugs whenever updates are released, ZWO classic philosophy is to lock you in to their own products which is obvious with the ASIair, however- above anything else users have requested time and time again for a custom park position being added -,which they have indeed introduced- but only to their own line of mounts! When constantly asked to introduce it to other mounts such as Skywatcher their answer is evident only by their silence. Tip: if you do get your equipment working - disable automatic updates , you have been warned!

### 5/5 — ZWO have serious issues

*2026-03-21*

2.5.1 is the straw that broke the camel’s back.  
New equipment bricked by the firmware on first use, even my local retailer got the same thing It freezes and locks up the only fix is a reboot, WiFi drop outs, guide camera failure, mount, EFW etc etc.   their response put a bug report in.  
Sorry but no as new equipment out of the box should work.

### 1/5 — Disappointment ASI 2600 PRO USER

*2026-03-20, version 2.5.1*

I’m am so disappointed in ZWO. The are building this wonderful equipment, but they can get the software right. The SOUTHERN HEMISPHERE the polar alignment hasn’t worked for over a year. But the seestar seems to be able to work. Now the latest issue, with the updated software is WiFi is un-functional. Can’t even down load 1 photo for review. $2500 of scrap camera at the moment. 
Hope they sort thing out shortly.

### 3/5 — Bring back progress bar

*2026-01-13, version 2.5*

Please bring back the autorun visual progress bar on the main screen. It is much easier to see at a distance and when half asleep.

### 4/5 — Une version française ?

*2026-01-06*

Bonjour l’application est nickel mais ont auras quand la mise à jour pour une version française ?
