NGC 6814
Object
NGC 6814 is a Seyfert galaxy, which means that it's a strong radio-emission source. You can find NGC 6814 between the constellations of Aquila and Sagittarius,
which is a rich field in the milky way. That means that the object lies behind some dark clouds
in the MilkyWay. We are lucky that NGC 6814 is a bright galaxy so most of the light comes though the dust.

Comments
I needed to capture the data on two nights and had some difficulties with placing the object on the right place on the
CCD-chip. As a result I lost some space on the borders with the layering.
