NGC 1144


Click on image for larger version.

If this image was a Far Side cartoon, the caption would read " When Galaxies Collide." Observational evidence seems to indicate that the elliptical galaxy to the upper right of NGC 1144 (center) recently punched right through the heart of what used to be a regular spiral galaxy. NGC 1144 has now developed a distorted ring-like structure that has spectacular star formation and high velocity gas (600-1,000 km/s). In fact astronomers have theorized that either the nucleus of NGC 1144 is releasing a jet of gas in our direction- or the nucleus itself is being ejected towards us. The HST image to the right shows the spiral nature of NGC 1144. Our ground-based (though low-resolution) shows the color of these galaxies and the ring of material that has formed during this galactic gala some 300 million light years away.

Equipment

20in RC Optical Systems telescope Operating at f/8.4
Paramount ME Robotic Telescope Mount
SBIG ST10XME CCD camera with color filter wheel

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

Luminance = 60 minutes binned 1x1
Red = 10 minutes binned 2x2
Green = 10 minutes binned 2x2
Blue = 10 minutes binned 2x2

  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp wasapplied 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.
