Goldtop57 I just took your suggestion and used BIN 2 for preview and it works. I got a image on the ipad and it looks good. However, when I looked on the memory, it showed images in bin 1 and bin 2. The reason is that I set the autoplay to .2 seconds and 3 exposures in bin 1. I shot another set in bin 2. The bin 1 image was not on the ipad screen, but the bin 2 image WAS on the screen and like I said, both sets of image were on the memory stick. some success, but I want to try it on the mount and the guide scope, too Thanks for your advice.
