NGC 7023: The Iris Nebula Captured from a Light-Polluted Sky
Astrophotography often conjures images of pristine, dark skies. However, the dedication of sky-gazers can overcome even significant light pollution, as demonstrated by this breathtaking capture of NGC 7023, more commonly known as the Iris Nebula.
This stunning image is the result of 7 hours of meticulous exposure time, a testament to the patience and perseverance required for capturing faint deep-sky objects. The photographer bravely tackled a Bortle 8 backyard, a level of light pollution that typically makes such endeavors challenging.
To achieve this level of detail and color, a specific setup was employed:
- Telescope: Askler V Telescope
- Camera: Sony a6300
- Filter: Baader Moon and Skyglow filter
The Baader Moon and Skyglow filter is a crucial tool for urban and suburban astrophotographers, helping to reduce the impact of light pollution by blocking specific wavelengths of artificial light. This allows the fainter light from deep-sky objects like the Iris Nebula to shine through more prominently.
NGC 7023, located in the constellation Cepheus, is a reflection nebula illuminated by the hot, young star HD 200775. Its ethereal blue glow and the surrounding dust clouds give it the appearance of an iris, hence its common name. Capturing such detail from a light-polluted environment is a significant achievement and inspires fellow amateur astronomers to keep aiming for the stars, no matter their location.
