I took this over several nights. I ended up only using less than half the data but its still about 6 hours worth.
Ha and O111 bicolour image of the Pencil Nebula. I was surprised by the ball of Ha nebula to the side with some ripples in it as well.
CDK17, FLI Proline 16803, 5nm Ha and O111 filters, PME mount.
