Description

I've captured the Heart Nebula before, but this time I wanted to start from scratch and capture 20+ hours on it and see if I could improve from a couple years ago.. It's captured using narrowband filters and processed in the Hubble Palette.

All of the data was captured in September, 2019.

Optolong Ha: 125x240" (gain: 139, offset: 21)

Optolong OIII: 109x240" (gain: 75, offset: 15)

Optolong SII: 104x240" (gain: 139, offset: 21)

Integration: 22.53 hours
