NGC 6445: The Box Nebula

Not much information exists about this nebula. Aside from its unusual shape, which is probably partly due to our perspective, this nebula exhibits bright colors and extended nebulosity. These outer filaments extend 2-3 times the diameter of the bright inner portion. Perhaps the radiation from nearby stars are affecting this nebula's outer structure.

Meade 16in LX200 telescope operating at f/10

SBIG ST8E CCD camera with color filter wheel

LRGB color production was used to create this image.

One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

Luminance = 50 minutes binned 1x1

Red = 10 minutes binned 2x2

Green = 10 minutes binned 2x2

Blue = 20 minutes binned 2x2
