This image, which includes the string of galaxies known as Markarian's Chain, as well as the galaxy M87, is in the constellation Virgo.
It was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue NP127is.
This image is a stack of 9 eight-minute exposures that were calibrated, defect-corrected and stacked using AIP4Win Version 2.
A Sigmoid scaling was applied to bring out the myriad of background galaxies and prevent burning out the galaxy cores.
This image has been resampled down from its original size of 4008x2672. Clicking on it will show a full-sized version.
The map below shows most of the objects in this field.
Clicking on it will bring up a larger version.
The three digit number after each object designation on the map is the magnitude,
with the decimal point omitted (i.e. mag 17.2 is represented as 172).
The galaxy cluster is the upper right corner is Abell 1526, which is more easily seen in the large version of the image.
