This pair of large, faint
emission nebulae are difficult to observe visually, requiring moderately large apertures
to be detected. IC 405, on the right, is also known as the Flaming Star Nebula and
contains the hot, blue variable star AE Aurigae. Radiation from AE Aurigae causes the gas
in IC 405 to glow red, while dust creates the bluish reflection nebula near the
star. AE Aurigae formed in the consteallation Orion and is traveling through IC 405 at
about 100 kilometers per second. IC 410 contains the open star cluster NGC 1893, which is
actually easier to see in a telescope than the surrounding nebulosity.

Exposures: LRGB: L 10 x 6 minutes: R 11 x 6 minutes: G 10 x 6 minutes: B 10 x 6
minutes: RGB binned 2x2

Technical Notes: Individual exposures were obtained using CCDAutoPilot2 and then sigma combined. The RGB image was created in
Registar 1.0. Reduce Noise was applied to the RGB image and to the dim portions of the
luminance image. A high-pass filter with a radius of 4 pixels was selectively applied to a
copy of the luminance image.
