Deep in the star fields of Aquila lies SS 433 aka V1343 Aquilae. Discovered in 1977, researchers noticed spectral shifts alternating between red and blue shifts. The star is also embedded in a supernova remnant, and is also a powerful producer of x-Rays.

The star system consists of an A type star orbiting either a neutron star or a black hole. The companion star loses material to the other object forming an accretion disc that is subject to extreme heating as it spirals in. In the process giving off intense x-rays and jets of material above and below the accretion disc. These jets precess around in a period of 163 days, and travel at 26% the speed of light.
 
The two object orbit each other with a period of 13 days and is located 18,000 light years away. Astrophysicists call the object a micro-quasar.

I also preformed a photometric observation and came up with a magnitude of 14.46 in the "v" band and uploaded it to AAVSO.

300 second exposures through R/G/B filters with the Ed80CFT refractor for the color image, and a 600 second exposure through a V filter for the photometric observation.
