▶ Plate Solving
Offline plate solving can be done in a few seconds.

For those new to astro photograpy, here is little bit of explanation what plate solving is. It is a way of defining the actual direction of the telescope when an image has been taken. A camera takes an image of the night sky, then a software will analyze the star patterns and by comparing them with data from various star catalogues it will "understand" where it is pointed to. Then this information (usually repeated in various directions) can be used in various ways, but most frequently it is being used to calibrate / align the mount, so that you can use it to point at a subject of your choice without need for "star hopping", use of a finderscope, etc. It can also use this information to improve the pointing accuracy of the mount. Basically it's a very cool and useful feature.

▶ SkySafari Bridge
The user can use the Skysafari app to control the mount through ASIAIR, choose the target and go.

▶ Supported cameras
ASI USB3.0 camera, ASI cooled camera, ASI mini cameras. (It can not support ASI120MM/MC camera)

USB2.0 Port

ASIAIR comes with 4 USB2.0 ports, you can connect up to 4 USB devices and don’t need USB Hub.

Power Supply

ASIAIR need 5V@2.5A external power supply, it’s micro USB port. Normally, ASIAIR consumes only 500ma current. but peak value would be 2.5A, so please use the power cable come with ASIAIR. other cables may be too thin and cannot provide enough power. we also provide one 12V-5V DC Converter, so you can connect ASIAIR to the 12V power supply as most Astro device.

SD Card and Card Reader

There is one 32GB Micro SD card that comes with ASIAIR. The OS (operation system) is running from this SD card and 25G space left for the user to store images. The user can use this SD Card Reader to transfer the images to your PC and processing. There is risk that the SD card may become corrupt one day, therefore we highly recommend you to back up your SD card as soon as you receive your ASIAIR device. Please find more detailed information in the ASIAIR Quick Guide. (Scroll down to the bottom of this page, there is a link to an backup application.)
