Chris, I’ve looked at the log you posted and I note some strange stuff. The imaging session started at 9:33 with images of 240 seconds. The first image was downloaded at 9:37:52 and the second was downloaded at 9:42:10; both these images took about 20 to 25 seconds to download after the acquisition which is normal. The 3rd one though finally downloaded at 9:50:24. That’s 8 minutes 14 seconds since the previous download and that is roughly 6 minutes unaccounted for? It looks like the camera is not releasing the image for download and BackyardEOS timeouts (or BackyardEOS is unable to complete the download) ~ I’ve never seen that before but there is a first for everything I guess
