NGC 5351

Click on image for larger version.

NGC 5351 and NGC 5349 float together at around 100 million light years away. Astronomers found that the radio emissions of HI (redshifted 21cm line) surrounding NGC 5351 extend about 1.4 times the size of the galaxy that is seen in the optical wavelengths of light. Astronomers can use this information to determine the mass of a galaxy (in terms of its luminous and "dark" constituents).

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 = 90 minutes binned 1x1
Red = 20 minutes binned 2x2
Green = 20 minutes binned 2x2
Blue = 20 minutes binned 2x2

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.
