M74

Click on image for larger version.

M74 is one of the dimmer galaxies in the Messier catalogue. The galaxy is estimated to be 35 million light years away and about the same size as our own galaxy (100,000 light years across). Many bright pink spots line the blue spiral arms. These pink regions are the stellar nurseries from which the bright blue stars in the spiral arms are born.

Equipment

Meade 16in LX200 telescope operating at f/10
SBIG ST8E CCD camera with color filter wheel

L R G B color production was used to create this image.

Luminance = 60 minutes binned 1x1
 Red = 24 minutes binned 3x3
 Green = 24 minutes binned 3x3
 Blue = 24 minutes binned 3x3
  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

  • Digital Developement (DDP) via Maxim/DL was also used in order to display the the very dim and very bright details of the image simultaneously.
