Hi Mike,<br><br>I used CCDsoft by Software Bisque to do the auto align folder, for aligning all 21 images, then chose the combine(average)tool. <br><br>I did have to go through and remove some hot pixels and cosmic ray strikes manually in Adobe PS first, which appeared on some of the images during the exposures over the 1.6 hour time frame.<br><br>The Full frame Movie is pretty cool too!, But have not put it up on my website yet as the file size is 2.8 megabytes. Not practical for most. <br><br> I will try to do and assembly as an animated gif in Adobe Image Ready to see if I can get it smaller.<br><br>Best Regards,<br>John Chumack<br>www.galacticimages.com
