I was in Plan mode last night. At 12:29 AM (image 57) something happened (the blinked image was divided into two: half of the DSO image on top and the bottom half of the image is white). At 12:48 ASIAIR had automatically switched to internal storage (this was image 61). Three images, i.e., 58-60 were deleted. (This is the second time this has happened). Today I was able to piece the first, flash-drive 57 images together with the ASIAIR stored images. Is the problem likely a faulty flash drive or a problem with the ASIAIR? At least the night was lost as the ASIAIR jumped in and saved the rest of the images. Any thoughts appreciated.
