The ASIAir Pro hardware is based on the PI4 board and OS has been rewritten for that platform - there will be a code branch to allow ASIAir Edn 1 to continue development in line with ASIAir Pro. USB3.0 is now standard on PI4.
ASIAir Pro has 64 GB of built-in space and a 64 GB flash drive giving total storage of 128 GB. PI4 has 4 GB of RAM and a new CPU - 30% faster than PI3.
The unit is now housed in a CNC milled aircraft-grade aluminum housing. The housing will have mounts to allow it to be installed on the finder foot and the finder/guide scope can mount on the ASIAir-PRO. ASIAir-PRO integrates simple power management with 4x DC outlets (3A each to 10A max total) - will be controllable from the ASIAir app (some ports will be PWM controllable for dew controllers).
It will have a DSLR shutter control line to control the snap socket on many cameras. It will support all the latest cameras and devices such as EAF. New software features for ASIAir-PRO have not been finalized yet - Autofocus/automated meridian-flips, Live stacking, and Auto-Focus are all possible! As ASIAir-PRO is a new software package PI3 boards will not support it - updated versions with non-PRO features will continue to be developed and released.
Definitely, the old generation of ASIAir will be supported with limited new features and bugs fix. Some features rely on the hardware performance will be only available on the ASIAir PRO. So we encourage users to upgrade to the new-generation to make astrophotography.
Key Features of the ZWO ASIAir Pro
Preview & Focus In Real-Time
The ASIAir Pro can preview images in real-time. It will de-Bayer images from a color camera and automatically white-balance images on the fly. You can also zoom-in on a small area and use the half flux width half diameter graph to perfectly focus your telescope. The ASIAir will also switch between automatic and manual stretching so that you can get the most detail out of your deep space astrophotography images.
Independent Autoguiding and Imaging
Autoguiding with a portable imaging setup requires you to bring along a laptop, often with multiple programs installed to both successfully capture images and autoguide. Often with multiple programs installed for image capture and autoguiding. However, the ASIAir is designed to handle both autoguiding and image capture at the same time so you can control everything from a single smartphone or tablet.
The 32GB TF card comes with ASIAIR PRO software, providing 20GB of free space.
A 64GB U-Disk is included.
You may also use any size of storage device you choose.
Four USB Ports to control up to four devices:
USB 2.0 Ports: The ASIAir has two USB 2.0 Ports that allow you to control two devices including a German Equatorial Mount.
USB 3.0 Ports: The ASIAir has two USB 3.0 Ports that allow you to control two more devices including a German Equatorial Mount.
Mounting your ASIAir Pro device:
The casing has been designed to be mountable to the dovetail bar on your telescope.
The casing is made of CNC machined aluminum. ZWO has tested the device and found that the casing should have almost no effect on the Wi-Fi signal.
The degree of heating the casing undergoes during use depends on its power consumption. The aluminum should help to dissipate the heat.
Software: The new ASIAir PRO software has amazing features. Two of these features are Live Stack and Automate Meridian Flip.
At the moment the app, (ASIAir) is only available with iOS/iPadOS/Android, but through some emulators for Apple technology you can try to run the app on these platforms.
The old generation ASIAir will be supported with limited new features and fixed bugs. Features which rely on the hardware performance will only be available on the ASIAir Pro. ZWO encourages user to upgrade to this new generation for the best astrophotography.
Cameras: Compatible with all recent ZWO cameras, as well as some Canon & Nikon DSLRs (with correct shutter release cable).
Mounts: Compatible with most equatorial mounts with the correct cable, often a EQDir cable. For a detailed list, please see the ZWO ASIAIR Pro manual.
Focusers: The ASIAIR Pro is only compatible with the ZWO EAF.
ASCOM/INDI: The ASIAIR Pro is not compatible with ASCOM & INDI drivers, as it is limited to the above.
