NGC 1187

This barred spiral Sbc(s)II galaxy is notable for how well the H II regions delineate the bar, inner ring, and almost the entire length of each of its half-dozen or so arms, "like beads on a necklace" to paraphrase Baade (1963). The two major arms appear to be extensions of the bar, which leads to the impression that they intersect perpendicularly with the inner ring of H II regions. It is the home of supernova SN1982R which brightened to a max of magnitude 14.6 on Oct 6, 1982. (Distance: 58 million ly)

LRGB color production was used to create this image.

The AO-7 unit was used to acquire this image.

Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 90 minutes binned 1x1

Red = 30 minutes binned 2x2

Green = 30 minutes binned 2x2

Blue = 30 minutes binned 2x2
