This week’s Picture of the Week features a very old favourite of mine, the interacting galaxies M51 in the constellation Canes Venatici.
This image comprises data taken with the original Hyperstar with a tiny little H9C OSC CCD, and the Hyperstar III with the M25C OSC CCD. Probably around 4 hours worth of data in all, and looking at the depth of the image, this one could do with quite a bit more data to do it justice.
