Christmas astronomy - The Moon & Jupiter

Most people around the world were treated to a great view of a waxing moon paired with Jupiter this Christmas night. The astronomical event presented itself to be the best way to start using our newly acquired telescope!

The Moon was spectacular offering plenty of detail (although at this stage of it's cycle it's increased brightness reduces contrast), and Jupiter was clearly visible with it's majestic bands and four Galilean moons - Europa, Io, Ganymede and Callisto - And since none of us had seen Jupiter through a telescope before, we were all rather chuffed. 


Although we'd not yet received our astrophotography kit, we shivered through the sub-zero temperatures (a crisp -20 deg C)  here in Cedar Rapids, Iowa to grab a few shots through the eyepiece with our cellphone cameras. Granted the images are really low-quality, we're happy we got anything at all on our very first astronomy outing!


Beginning with the Moon - 
























Using a cellphone camera our shot of Jupiter and its four Galilean moons couldn't obviously produce the detail we observed through the eyepiece. The image below is untouched and includes distortion due to the eyepiece barrel and the fact that we were trying to keep a cellphone centered at -25 degrees Celcius.









Attempting to clean up and re-size our original image gave us something a tad clearer (below).


























Both the observed and captured image above were 'mirror reversed' since our telescope is a Schmidt-Cassegrain design. A comparison between a 'direct' view versus the captured view is shown below. The rendering is a screen capture from Sky & Telescopes' Jupiter's Moons applet available here

Note: E = Europa, I = Io, G = Ganymede, C = Callisto

  1. A truly magical night indeed! The first glimpse of the surface of the moon fascinates one's mind in so many different ways that it becomes hard to take your eyes off it and one can't possibly ask for anything more for Christmas when you get to see Jupiter and 4 of it's moons.

    Great job everyone!!
