46cm f/4.5 Deep Violet

Note: This nebula probably nonexistent, notwithstanding my observation and the observations of many observers (the Herchels, Struve, Dreyer, Steve Coe). Deep photos of the region show nothing, I probably observed glare from Epsilon Ori. A cautionary tale...

Very faint and extensive nebula centered on Epsilon Ori, best detected by panning though the field and noting brightness changes in the background, looking straight at Epsilon the background is clearly not very dark at the center of the nebula
