Dusty Cepheus

These are only some of the dusty parts in the constellation Cepheus. Near the bottom center is DG179 (LBN 531) and near the bottom left is LBN532. Planetary nebula DeHT5 (LBN538) is visible above and to the left of DG179. I was hoping I would get more details in the dusty arcs that span across the image. A bit more aperture would have been nice but I wanted to keep the star shapes reasonable.

This was the first time in over three years that I bumped into astronomers again.

We again saw flashes on the horizon, but this time they were coming from the NW. My target for next week (if the weather holds) won't be in position until 1:30am, so I'll have some time to investigate the flashes.
