 All (CDSPortal) Send to within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR. The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding. Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).

• message of Brent A. Archinal (27.12.2005):
the IC makes no mention of a star cluster here, and neither do the discoverersof the IC 5146 nebula (the "Cocoon Nebula"), Espin (1900) and Wolf (1904).Collinder appears to have been the first to identify a star cluster here(even though he also used the IC 5146 name incorrectly), so the preferred namewould seem to be Collinder 470. Details of this are given in Brent A. Archinaland Steven's Hynes book "Star Clusters", pp. 127-128.
