I use both Sky Safari and Starry Nights 8 - SN8 in my observatory. On SkySafari, the FOV rotates as the view slews - perfect! But, SN8 does not. I did not realize this until the other night when I took 2 hours 90 degrees off what I wanted. SkySafari was correct but SN8 was not. Is there a setting I have missed to make that happen?
