NGC660
Image Information
| Quoted from NOAO/Adam Block:
NGC 660 is described as being a "polar ring" galaxy. Another remarkable
picture of this rare type of galaxy was recently taken by the Hubble
Space Telescope- the example in this case is
NGC4650A.
These galaxies are believed to have formed from the collision of two
galaxies in the past. In the case of NGC 660 it would appear that our
perspective is inclined from the axis of the disk so that the foreground
portion of the ring does not cross the plane in the middle- but instead
towards one side. The central region of this galaxy is considered a
"starburst" due to the extreme amount of luminous star formation.This
galaxy is estimated to be 24 million light years away.

| This image is compiled from 10 - 15 minute
each R, G, & B images and 22 - 15 minute luminance. A total of
13 hours of data was used for this image. All data was acquired using
MaxImDl/CCD version 5 using ACP. Images were reduced,
De-Bloomed, average combined and saved in MaxImDl version 5.
Alignment was done using Registar. The master images were combined,
registered and the color image created. Photoshop CS 4 was used for
cleanup of blooms, curves, and levels. The image data was
collected over Dec 3, 2009 - Jan 15,2010. The image is cropped more than
usual as I was having issues with the A08 and the frames were not
aligning closely.
