Description

I fit two different planetary nebulae into this same frame. Heckathorn-Fesen-Gull 1 (HFG1) is a planetary nebula in Cassiopeia. It was produced by a binary star system and discovered in 1982. The small circular bubble, Abell 6, is also a planetary nebula. It's diameter is around 3 arc minutes in the sky.

It's captured with narrowband filters. I put Ha in the Red Channel and OIII in the Green and Blue Channels.

All of the data was captured in October and November, 2019.

Astronomik Ha: 285x240" (gain: 139, offset: 21)

Astronomik OIII: 308x240" (gain: 75, offset: 15)

Integration: 39.53 hours
