Please consider to enable recording of capture time on images and single frame in videos to enable ASIAIR for use in occultations session observations. It is essential to introduce GPS (external USB would be great) support to keep time synced.
Those features are available with big limitation on only two cameras on the market, at the moment. It would be a great improvement for ZWO and an absolutely great appreciated by all amateurs involved in occultation observations. Please, refer to IOTA or IOTA-ES for any reference about technical requirements or contact me.
