In the animation I have included this time the 6 images with both the best 10% and the best 50% of the frames.<\/p>\n<p>The 10% ones are much more pixelated and lower resolution, especially in the first two images.  Typically I do two 30sec runs to start, one with autoalign turned off, to get a gauge of seeing, then on to compare.  Then I move to 120second runs, about the most for an f20 system that will not show Jupiter rotation&#8230; I have yet to figure our winjupobs to derotate and stack images&#8230;<\/p>\n<p><a href=\"http:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2017\/02\/jupiter20170131.mpg\">jupiter20170131<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>brr.. even a little colder this morn&#8230; -17C but no wind at all.
