Best of AOP - Galaxies


M88 displays a set of tight spiral arms and dust lanes in each. A recent supernova (1991) in M88 helped better determine its distance from us. Stars exploding in other galaxies can be used as a "standard candle" since astronomers know their intrinsic brightness (how bright it would appear at a known distance). Then, by measuring the brightness of the supernova, they can estimate its distance by using the properties of light (things appear dimmer the further away they are). M88 is calculated to be 60 million light years away by this method.

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.

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 = 105 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
