Jupiter was high up and was showing the Great Red Spot leaving the face.  The first image run of the night captured a moon shadow but I am not sure if it was Europa or Io yet.<br \/>\nI left the system running unattended for 10 minutes and tracking was not perfect and Jupiter drifted out of the field of view.  I have to start researching a method to allow the software to command the scope to keep the target centred in the Field of View.<\/p>\n<p>Image runs were 90 seconds.    Exposures were a little high and got worse at times, showing transparency getting worse.  Exposure ranged from 40 to 50 ms.<br \/>\nProcessing started with replaying the .AVIs and discarding any that had Jupiter move out of the FOV.<br \/>\nCastrator was then used on the remaining to shrink the image down to 400&#215;400 pixels and centre it.<br \/>\nAutoStakkert! was then used to analyze set approx 20 alignment points and processed with the best 75% being used here.<br \/>\nRegistax was then used to autobalance RGB and to do wavelet processing using my &#8220;jupiter&#8221; settings.<br \/>\nFinally, a linux bash script annotated the images with the UT time and equipment notes, then combined them into an animated .GIF and an .MPG video.<br \/>\nThis is the animated .GIF below.<br \/>\n<figure id=\"attachment_6882\" aria-describedby=\"caption-attachment-6882\" style=\"width: 400px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2016\/04\/jupiter-1.gif\" alt=\"20160409 from 01:32 to 02:04 UT\" width=\"400\" height=\"426\" class=\"size-full wp-image-6882\" \/><figcaption id=\"caption-attachment-6882\" class=\"wp-caption-text\">20160409 from 01:32 to 02:04 UT<\/figcaption><\/figure><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A 3 hours gap in the cloud cover Friday evening had seeing and transparency at &#8220;average&#8221;.
