Slow moving asteroid?

    asteroid moving in front of star?

    enter image description here

    three images, red green and blue stacked together

    big object in red (i band), the red colour of an orange star

    big object in green (r band) , the yellow colour of an orange star

    small double or moving object in blue (g band)

    red + green makes yellow or orange, the big orange "star"

    blue + red makes magenta, that purpley pink "star" inside the orange

    blue + green makes cyan, the "green star"

    So possibly, an asteroid was caught during several exposures of the blue (g) filter against a background orange star?
