Description

This image shows how close Jupiter and Saturn were on 20 December 2020, seen from Maceió-AL, Brazil, at 21:00 UT.

This was the first image where the two planets fit mutually in the Field of View (FOV) of the 12-inch telescope in prime focus with the QHY183C camera. During the two days that preceded the occasion, I had to use a f/6.3 focal reducer in order to accomplish that. And, before that, I had resorted to a 80 mm APO with a 2x Powermate, and, then, a C8 with the f/6.3 focal reducer.

30% out of about 1500 frames were stacked with AS!3 and then post-processed with Photoshop.

I was pleased with the results. And I hope you can enjoy!

This image was achieved with the collaboration of my friend Romualdo Caldas.
