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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
