NEW PHOTO, The Flaming Star Nebula, IC405
This winter has been extremely cloudy up here at 65°N, but I managed to use those few clear moments to capture enough data for a new cosmic artwork from our night sky.
IC405, the Flaming Star Nebula in Auriga, is a beautiful velvet-like emission nebula with a reflection nebula component. I somehow managed to capture good exposures of the reflection component despite my light-polluted conditions.
I decided to create a two-panel horizontal panorama of IC405, and the result is quite dramatic.
The total exposure time is 36 hours, with the data collected between 2024 and 2026.

The red emission originates from hydrogen (H-alpha), and in narrowband images the bluish tones are usually produced by ionized oxygen (O III). In this case, however, the blue area in the image is a broadband reflection nebula. This color combination closely represents the nebula’s natural visual appearance.

INFO
Rippling dust and gas lanes give the Flaming Star Nebula its name. The colors are a mix of red light and blue light emitted by AE Aurigae but reflected to us by surrounding dust. The two regions are referred to as emission nebula and reflection nebula, respectively. The Flaming Star Nebula, officially known as IC 405, lies about 1500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga)
