I did several clips, and this was the last, coming up pretty clear. But I have others in the middle that showed a noticeable amount of scintillation which caused the details, especially along the terminator, to ripple. While this is caused by atmospherics, air densities and movement and all that, I don&#8217;t know why they changed so significantly, back and forth, in the half hour or so that I was out. Yet this also shows that, unless conditions are optimal, a long exposure of a dimmer subject (everything else in the sky, really,) would easily be blurred by these changes, no matter how stable and sharp the rig, no matter how accurate the tracking system.<\/p>\n<p>I&#8217;m gradually getting closer to doing some <em>real<\/em> telescope stuff, and expect to have some results this winter.
