I captured this planetary nebula with two narrowband filters, Ha and OIII. I put Ha in the Red Channel (100%) and OIII in the Green and Blue Channels (100% each). It was rather small on my telescope so I drizzled and cropped it.

Astronomik Ha: 153x240" (gain: 139, offset: 21)
Astronomik OIII: 161x240" (gain: 75, offset: 15)

Integration: 20.93 hours
