Double Star Index

  • Just as small catalogue of images I am creating that I hope to improve as I go along.
    I started by placing images on each page as I took them, but now I have decided to make a separate page for each constellation.

  • Auriga

  • Leo

  • Ursa Major

  • Coma Berenices

  • Bootes

  • Draco

  • Hercules

  • Random

  • 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 equivalent to a 12mm EP, giving a magnification factor of approximately 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
