Jupiter and GRS


Yesterday evening the sky was clear and seeing was good with a relative humitidy of 90%.  Using Sky & Telescope I was able to know when the Gread Red Spot (GRS) on Jupiter faces directly to earth. This was around 20h20 UT. I made  observations using my Dobson 12" and 9mm oculair and immediately recognized the big spot. Using my TAL200K and ASI224MC I took some pictures  and movies of Jupiter and the GRS.
