- The Millennium Star Atlases in the reading room are a good place to locate
setup stars for your targets.
Here's a good place to get
finding charts for your objects for use with CCD imaging projects.
Choose the 'SkyView Query Form' interface, and under Optical highlight 'Digitized
Sky Survey (DSS)', input your coordinates, under `Common Options'
pick a size of 1 degree, and download the FITS file. Then load it into IRAF,
smooth it using 'gauss' with sigma=1. Display the smoothed image with zsc- and zra+ or
some other appropriate value of z1 and z2, make
the stars black in ds9, and then use 'wcslab' to add a coordinate grid.
Scale the image to highlight only the bright stars, with the intermediate ones still visible
but looking faint and the background a very light grey. xv will be helpful for grabbing
the image and changing it to greyscale and storing it. Then print out the chart and
mark your object on it in black ink or with a pencil.
An example of what it should look like is here.
