NGC5466 is just another globular cluster. This one can be found in constellation Bootes. It is more less in the same distance from us (51,800 light years) and from galactic center (52,800 light years). With apparent magnitude 10.5mag it is available for medium sized telescopes, but is much fainter than brightest globular clusters in the sky. NGC5466 is a little bit unusual insofar as it contains a blue branch of stars – it can be spotted in the image. Most globular clusters contains very few blue objects. This cluster is thought to be the origin of stellar stream called 45 Degree Tidal Stream that spans in the sky from Bootes to Ursa Major. This stream has been discovered in 2006 and spans on both sides of NGC5466 cluster along its orbit around galactic centre.
I made image below in my backyard observatory with Meade ACF 10″ telescope and QHY163M camera on EQ6 mount. It is total 210 minutes of exposures through LRGB filters with 2 minute subframes.
