I don't know. The ASIAIR has made my astrophotography so much more enjoyable.
The app isn't perfect, but there's always room for improvement in any software/hardware. I've also found the support to be fairly good so far and the app keeps getting better over the years.
Maybe I feel that way because I started playing with astrophotography 15 or so years ago. There were lots of cables, software glitches, and mosquito bites to contend with back then. These days I go to bed and occasionally get woken up if local wildlife (or the stupid neighbor's cat) wanders too close and triggers my alarm system.
I received a long reply from ZWO support. I'm still trying to decipher it as it assumes that I'm using the pc-based ASI software control. I'm using an ASIAIR and the app on my tablet to control things, which is a bit different.
From what I can tell so far, via testing and the support response, the CAA needs to be able to rotate the full 360 deg even when you have set the range to 180 deg. The 180 deg range will move around on identical Plan runs on different sessions. Stuffed if I know how the ASIAIR decides on where this 180 deg range will be set or why you'd describe it this way if it moves around.
I was able to find the so called "Mechanical Zero" position and I haven't had the unit rotate past this point yet. I found this position by using a hand controller during testing for possible cable snags. The app control also uses this hard limit.
This position hasn't changed throughout all my testing so far.
The random 180 deg range works for me as I've set my rig up to pause either side of the meridian flip long enough to avoid any collisions. The L-OAG (when attached) sticks out the opposite side as the filter wheel, so it's always been a no brainer to avoid the pier no matter the rotation of the imaging equipment. YMMV.
