NGC 281: Capturing the 'Pac-Man Nebula' Through Light Haze
Sometimes, even when the skies aren't perfectly dark, astrophotography can still yield beautiful results. This capture of NGC 281, also known as the 'Pac-Man Nebula' (though my daughter insists it looks more like a shrimp!), is a testament to the power of narrow-band imaging.
The Challenge of Light Haze
Living in a Bortle 5 zone with a touch of light haze, I often prefer darker skies. However, this session demonstrated how effective dual-band L-Enhance filters can be in cutting through atmospheric interference. The challenge was to capture the intricate details of NGC 281 without relying on broadband filters or artificial star reduction.
Acquisition and Processing Details
- Telescope: 150p Quattro f/3.6
- Camera: Unmodified Canon 60D
- Exposure: Approximately 2.5 hours
- ISO: 3200
- Filters: L-Enhance dual band
- Processing Software: ASTAP, SIRIL, RawTherapee, Gimp
This image was processed using only narrow-band data for the stars, avoiding broadband filters and StarNet. While the lack of Ha sensitivity in the Canon 60D is still a limiting factor, I'm pleased with how the narrow-band imaging allowed the nebula's structure to shine through despite the less-than-ideal conditions.
A Flexible Approach to Astrophotography
This experience reinforces the added flexibility that narrow-band imaging provides. It's a great way to continue pursuing our passion even when perfect skies are elusive, proving that creativity and the right tools can overcome many obstacles in capturing the wonders of the cosmos.
