Arp 286-Galaxy Trio in Virgo
« on: 2010 August 05 17:48:50 »
I know it's nebula season but I'm struck on galaxies.:D  Arp's Atlas of Peculiar Galaxies contains 338 photographs that document many unusual galaxies. Some are very familiar such as M51. I am particularly fascinated by interacting galaxies and Arp's catalog contains many fine examples of these interesting objects though many are quite small. Arp 286 has 3 prominent galaxies. NGC 5566 is the largest of the 3 at 6.6 x 2.3 arc min and is almost exclusively yellow while NGC 5569, the smallest at 1.7 x 1.6 arc min is blue. The 3rd, NGC 5560 is 3.6 x 0.9 arc min, multicolored and the most distorted by it's interaction with NGC 5566. NGC 5566 seems to have some distortion as well. Arp thought a connection between the two was not visible but it has been suggested that there may be a faint connection from the tip of NGC 5560 to the core of NGC 5566. Don't think a connection is visible in this image. If it's there, need a lot more signal to demonstrate it.  I did collected 15 hours of data hoping to have enough signal to try to bring out some of the detail in these small objects. Hope you like it.

Thanks for all the nice comments. Harry, I'm not sure what "slightly soft" means but it sounds good to me so I'll take it as a compliment. :D

Steve,

Very nice indeed.  Is the galaxy in the lower right really that blue?

Hi Wade,

NGC 5569 is blue though likely not "that blue". Indeed, I pushed the color in the whole frame as I really like the look of vibrant color in my images. I have at times pushed the saturation a little too much but hopefully not on this image.

Congratulations on APOD.  Looks like you toned the saturation down a bit.

Thanks Jack,

The image submitted to Jerry at APOD was the same one posted here in this thread. So, there was no change in saturation.
