Description

Since the beginning of the week, Jupiter and Saturn have been giving a real show, just after sunset on the West horizon. On Tuesday the conjunction still had the presence of the new moon and today I was able to register the two planets close to each other at an angular distance less than 0.2 degrees. Observation with eyepieces is also unbelievable, seeing the two giants and their moons in the same field of view was unforgettable. On Monday (12/21) they will be even closer at about 6 arcmin (minutes of arc)
The images below were taken with a Celestron 8 ota at F10 and a Canon Ti1 camera, which is not ideal for planets, but allowed to fit both planets in the same field, since it has a relatively large sensor (much larger than my ASI290 planetary camera). The first image had 1/15 seconds of exposure iso 800 and you can already see the rings of Saturn, in the second image I used 2 seconds of exposure iso 800 to highlight the moons Io, Europa, Ganymede and Callisto, in sequence close to Jupiter) and Titan ( the "left" of Saturn). You can still see the star HIP99314 on the right. A zoom on Saturn also showed the moons Rhea, Tethys and Dione, but I believe that the web resolution will not allow this observation.
