Twilight lasts a long time after the Sun has set and before it rises, because of all the dust in Mars' atmosphere. At times, the Martian sky takes on a violet color, due to scattering of light by very small water ice particles in clouds. [4] Generating accurate true-color images of Mars's surface is surprisingly complicated. [5]
A triple conjunction between Mars and Jupiter occurred. At the first conjunction on May 26, 929, Mars, whose brightness was −1.8 mag, stood 3.1 degrees south of Jupiter with a brightness of −2.6 mag. The second conjunction took place on July 4, 929, whereby Mars stood 5.7 degrees south of Jupiter. Both planets were −2.8 mag bright.
Even though star trail pictures are created under low-light conditions, long exposure times allow fast films, such as ISO 200 and ISO 400. [6] Wide-apertures, such as f/5.6 and f/4, are recommended for star trails. [5] [8] The star trails captured with 136 minutes long period of exposure in Eleebana, NSW, Australia on 3 March 2019
