The new mount is still not polar aligned,  so there was more drift than I was happy with.  This is the first time the x2 antares barlow was used.  Focus is still quite soft (I still do not have a full length extension on the electric focus controller) and that will get better.<\/p>\n<p>Again, the camera would not come to focus with the x2 barlow, but it did with the 90 deg diagonal.  So I am still all confused up as to orientation, flipx flipy choices.  I had to go into stellarium to see what Saturn should look like and edit it after the fact.<\/p>\n<p>This was a 240 second run with 60ms exposures.  The best 25% of 3970 frames were used.  I love the scale of 3600mm focal length&#8230; Saturn is actually larger than a pinprick!<\/p>\n<p>So, altitude was still very low and Saturn was still in the Kingston SkyDome&#8230; so this again is a benchmark image, where future ones can only get better \ud83d\ude42<\/p>\n<p>Also attached is an image from Allsky1pi (with its new wider angle lens) camera system actually showing Saturn at the same time as the telescopic image was taken, approx 22:53 EDT Friday evening.  Saturn is 19deg altitude and is located centrally in the Kingston SkyDome.  If I had better prepared with a nap, I could have gotten up around 02:00 or 03:00 when it would have cleared the light pollution.<\/p>\n<p><a href=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann-299x224.jpg\" alt=\"\" width=\"299\" height=\"224\" class=\"alignleft size-medium wp-image-9577\" srcset=\"https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann-299x224.jpg 299w, https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann-1023x767.jpg 1023w, https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann-150x113.jpg 150w, https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann-768x576.jpg 768w, https:\/\/starlightcascade.ca\/blog\/wp-content\/uploads\/2021\/08\/image-20210730-225345ann.jpg 1280w\" sizes=\"auto, (max-width: 299px) 100vw, 299px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is one of a few imaging runs of Saturn taken Friday evening.
