| Exposure |
Twenty-nine exposures of 20 seconds each. Aligned,
stacked, and processed with AstroArt. The use of relatively short
individual exposures preserves the detail in the faint nebulosity
surrounding the four very bright Trapezium stars. The contrast has been
deliberately stretched to reveal subtle structure in the darker foreground
portions of the nebula. |
