NGC 672 (on the right side of the image) and IC 1727 (in the bottom left)
are interacting galaxies some 18 million light years distant. From each
other they are separated by only 88,000 light years- little more than
their own diameters. While outside of the "Local Group" of galaxies, these two
are close enough to begin to resolve some of the brighter stellar associations
and dust lanes. This gives the galaxies their granulated and bumpy appearence.
By examining these galaxies in the radio wavelengths of light, astronomers
have detected a large envelope of gas that surround these galactic friends.

color production was used to create this image.
Luminance = 90 minutes
Red = 20 minutes
Green = 20 minutes
Blue = 20 minutes
One iteration of L-R deconvolution (sharpening) algorithm using
CCDsharp was applied to the luminance image.
Digital Development (DDP) via Maxim/DL was also used in order to
display the the very dim and very bright details of the image simultaneously.
Due to the placement of the guide star it was difficult to position and
frame these galaxies. Since NGC 672 was the brighter of the two, the other
galaxy (IC 1727) sacrificed a bit of itself to the edge of the field.
