IC405, The “Flaming Star Nebula”

After imaging IC410, the next logical thing to image was its bigger companion, IC405. Known as the Flaming Star Nebula, it’s the other bright nebula within the hexagon of Auriga’s stars. The ripples at right are really nice (easily enhanced with LocalHistogramEqualization), but IC405 lacks the color contrast of IC410. The SII and H-alpha overlap … More IC405, The “Flaming Star Nebula”


This is not exactly a shining moment as an astroimager, because I completely messed up the polar alignment routine, resulting in smeared stars.  (When the CGEM tells you not to pick polar alignment stars too close to the pole, it means it!)  But NGC7000, more commonly known as the North America Nebula, is such a … More NGC7000

The Moon: Narrowband as a Neutral Density Filter

Sometimes the moon just has you beat. With no significant narrowband targets in the sky and the moon well past a quarter, I figured I’d take its portrait before calling it a night. As with my previous image of the moon in conjunction with Venus, narrowband filters make great neutral density filters to dim the … More The Moon: Narrowband as a Neutral Density Filter
