Last night was suppose to be my first night of taking some photos of the moon surface using my DSLR 400. I set the alignment up and was away, everything was fine. As I was a little early for the moon to arise I just went to Pluto and had a look and same with Saturn and Jupiter. I finally decided to try and get pics of Saturn as it was very clear, however the GPS dropped out. So I tried realign 4 times but each time it failed. Has anyone got an explanation why? I must add I used a bright star, the moon (as it was up by now) and Saturn to set the alignment again.
