The Pacman Nebula is something I’ve been wanting to image for quite some time. Mostly because it looks like what it is called… Pacman. NGC 281 is a very bright emission nebula in Cassiopeia only 9,200 light years away. Emission nebulas emit light due to ionized gases within the cloud.
To date, this is the longest image I’ve ever captured, coming in at 30 hours of imaging time! And more amazingly, I’ve had 9 nights of clear skies over the course of about 3 weeks. It usually would take 1-2 months to get this amount of imaging time.(more…)
