About this image

Here is the 2020 version of the "Christmas Star". 

In Pete's words: "Jupiter and Saturn approaching Great Conjunction. This image was taken approximately 24 hours before the appulse of Jupiter and Saturn on 21 December 2020 – image date 20 December 2020. A glorious evening’s view of the two planets just 9.5 arcminutes apart. Easily split with the naked eye, it was also possible to view both worlds through the eyepiece of a telescope in the same field of view as tangible discs; quite a sight!

Image is a composite of two separate RGB sequences for the planetary discs, combined with an over-exposed field shot to reveal the moons. A C14 was used, along with an ASI 174MM planetary camera. A 0.63 focal reducer had to be employed to get everything on a single chip (just!). Image was taken from Thornton, Leicestershire from a location with a very flat, zero-degree horizon. This allowed the planets to be followed almost to setting, fading out a few minutes before reaching the horizon due to haze."
