Mars and Jupiter Approaching Conjunction

I had to take advantage of a very clear sky, less the 98% Moon but it was in the WNW and I was shooting in the ESE, to capture the approach of Mars to Jupiter. According to Stellarium the conjunctions will occur on January 5th and 8th with Mars eclipsing Jupiter on January 6th & 7th, please correct me if I am wrong. This shot was one of 13 in two and a half minutes, the temperature was 14° F (-10° C). This image was shot at 4:32 a.m. with the following gear and settings: Canon Rebel T7i, Rokinon 85mm lens, f/4, ISO 1600, 4 seconds. The image contains Jupiter (large and to the left of course) with Mars right and above, then you have the star Zubenelgenubi II below Mars. Of the 13 images this was not the very best but you can’t throw out an image with a meteor just above the star. This image is cropped from the original 85 mm focal length.

Upon examining the image under Full Resolution you can see the fat stars, 4 seconds was too long for the lens but again, can't throw out the shot with the only meteor. Please enjoy.
