NGC 2419 - Intergalactic Wanderer
NGC 2419 is an unusual globular cluster because it is so far away. It's out there orbiting the Milky Way beyond the Magellanic Clouds. It's also a great fit on Hubble's detectors because of its distance and large size, which is double great because there is a robust set of data in the archive, which made filling the chip gap rather trivial. Its nickname, Intergalactic Wanderer, is somewhat of a misnomer because it is orbiting rather than wandering (read the wiki article) but I think it's a great name and gives the cluster some character.
Data primarily came from this proposal:
Red: hst_11903_41_wfc3_uvis_f814w_sci + hst_11903_41_wfc3_uvis_f775w_sci + hst_11903_41_wfc3_uvis_f625w_sci
Chip gap filled with:
Red: ACS/WFC f814w (j8io01071_drz) + hst_11035_04_wfpc2_f814w_wf_sci
Green: ACS/WFC f555w (j8io01021_drz) + hst_11035_04_wfpc2_f555w_wf_sci
Blue: ACS/WFC f475w (j8io01031_drz) + hst_11035_04_wfpc2_f439w_wf_sci
North is NOT up. It is 44° counter-clockwise from up.
