About this image

I love the way narrowband astrophotography allows me to obtain images like this even during a full-moon!

Any DSO astrophotographer will know that the clouds always seem to clear during a full-moon!

This image consists of just two exposures of 10 minutes (H-alpha) and 20 minutes (OIII). Guided using PHD2. I'll try stacked images next time.

The nebula is no longer a crescent in this narrow-band view, more like "The Brain Nebula".
