Description

After finishing with Venus, I decided to try something a little different by imaging a double star. The obvious candidate was Sirius with its bright A-type main sequence primary and dimmer white dwarf companion. Sirius B is slightly past its 31.5 AU apastron, similar to the distance between the Sun and Neptune. The stars will gradually close in until they are 8.2 AU apart at periastron in 2044.
