Finder Charts

This finder chart form lets you generate finder charts centered on a given sky position (in B1950.0, J2000.0, or Galactic coordinates) with a given field width and magnitude limit. To prevent any charts from getting overly crowded, only the brightest 200 objects will be plotted. Also note that the gnomonic projection used for these finder charts creates a larger distortion as you move further from the field center, and only matched objects are displayed.

If these restrictions are a concern, consider retrieving the data using the sky box query form and plotting up the data with another plotting package.

Finder Chart Interface

If you enter an object name below, the SIMBAD name resolver will be used to attempt to determine the position of that object on the sky. Entering an object name overrides any positional information entered below. If you want to search around a specific position, leave the object name blank. Object Name:
Enter your central coordinates in the boxes below. Both sexagesimal and WCS (e.g. - decimal degrees for longitude and latitude) format are accepted.
Right Ascension/Longitude: Coordinate System: B1950.0J2000.0Galactic Declination/Latitude: Field Width: arcminutes
A note about magnitude limits: The MAPS Catalog is incomplete for bright objects (magnitude < 12) and has a faint end limit that varies with each POSS plate but ranges from 22.5 to 23.5 in O.
Faint magnitude limit:	in O Stellar Magnitude in O Integrated Magnitude in E Stellar Magnitude in E Integrated Magnitude
