I was able to get out last night before a bit of snow rolled in today. I started with nice clear cold skies at 12F winds SSW @ 4 MPH dew point of 4F.
I used my 203mm reflector with several magnifications from 160x to at highest 240x. My best view was with a W80A filter. I tried a 82A, and an apodizer
Start time 20:10 end time 20:56
System 1 = 282.92. System 2 = 237.22 System 3 = 34.92
I was able to detect the GRS move during my observation . Europa had just cleared and Ganymede and Io sat as a double star. I noticed a great deal of boiling trailing the GRS and two noticeable festoons. My oldest daughter was out for some of the observation with her sky scanner looking at the full moon.
A very enjoyable night at the telescope.
