Make annotated finding charts (mirror site)

This form allows you to make annotated finding charts for a given astronomical target, by specifying either the coordinates, or an object name to be resolved by Simbad or NED. The finding charts use data from the Digitized Sky Survey, and they are annotated with the object coordinates, a 1-arcminute circle in the center for scale, and the object name if provided, as in this example.

Target name:  (Will be resolved by Simbad/NED if no coordinates given below. Otherwise, it is used as a label for the plot but not for coordinates.)

RA (J2000):
Dec (J2000):


Field width (arcmin):   Default: 30 arcmin. Max: 60 arcmin.
Field height (arcmin):   Default: same as width. Max: 60 arcmin.

Show outline of detector (with size specified below):

Detector width (arcmin):
Detector height (arcmin):   Default: same as width.

Dark background (black sky, white stars)
White background (white sky, black stars; better for printing)

This code was created by Eric Jensen. This page is maintained by Mittelman Observatory at Middlebury College. This tool is part of the Tapir package (upstream primary site, this mirror site) for planning astronomical observations; the source code is freely available.

The upstream primary site includes a more robust set of tools optimized for planning follow-up observations of periodic targets, especially transiting planets.
