Double Stars - Auriga

  • Note:

    All images are at 1:1 scale taken with the same equipment (120mm refractor, 1000mm FL, Canon 450D DSLR) and same magnification unless stated. The Canon 450D gives equivilent to a 12mm EP, giving a mangnification factor of approximatly 80x. This means that the split between all stars can be compared against each other. Exposure times and ISO levels are adjusted to give best image of both components but on average they are 4 seconds at ISO 400

    As the image shows, I could not split this double, although you can just see the secondary showing to the left of the primary. Magnitues of 5 and 8.2 respectively, at a distance of 159 L.Y.'s and with a separation down to 4.7", this was a difficult one to try.

    14 AUR (STF 653)

    This is a quintuple system, but I could only image components A & C with magnitues of 5.2 and 7.4. I am suprised that component B was not visibe at a magnitude of 9 and separation of 10". This multiple star system lies at a distance of 269 L.Y.'s

    26 AUR (STF753)

    Another multiple star system, components A & B are equal magnitued at 6.2 and only 0.1" separation, in which case it shows as a single star. Component C is visible at a magnitured of 8.4 and is just visible against the combined AB magnitured of 5.4.

    STF 872

    Anonther quadruple system, components A & B are shown with magnitudes of 6.9 & 7.4 respectively. This system lies at a distance of 158 L.Y.'s
    Details: Constellation: Auriga    RA: 06h 15m 39.1s    Dec: +36° 08' 55.3"    PA: 217°     Separation: 11.3"

    41 AUR (STF 845)

    A simple double this time, easy to split even at a narrow 7.7". Both components are almost equal magnitues at 6.1 and 6.8 respectively. This binary system lies 311 L.Y.'s away.
    Details: Constellation: Auriga    RA: 06h 11m 36.6s    Dec: +48° 42' 39.6"    PA: 356º     Separation: 7.7"

    59 AUR (STF 974)

    A triple system, component C too faint, but shown are components A & B with magnitueds of 6.2 & 9.5 respectively. This system lies a staggering 530 L.Y.'s distant.
    Details: Constellation: Auriga    RA: 06h 53m 01.4s    Dec: +38° 52' 08.9"    PA: 223º     Separation: 22.3"


  • 22:27 UTC      28-01-2013

    STF 681

    Another double, magnitueds of 6.7 & 8.7 respectively with a large split. This pair lies even further away at 615 L.Y.'s
    Details: Constellation: Auriga    RA: 05h 20m 39.2s    Dec: +46° 57' 49.6"    PA: 181º     Separation: 23.2"

  • 22:32 UTC      28-01-2013

    STF 764

    Finaly another distant pair at 503 L.Y.'s, magnitues of 6.3 and 7.4 make this a fairly even pair, with just a slight colour difference noticable.
