On the help page, specify the image you are interested in and the image will appear with right ascension and declination labeled. North is at right. East is up. Now that you are oriented with your image , you can find the corresponding region on a star chart . If you have your own star chart on paper or in a book, you simply find the proper right ascension and declination and then turn your chart so that north is at right and east is up.
Charts are also available on-line.
These charts are already restricted to a declination range of -8 to 0 degrees, similar to Stardial's images. This leaves you the task of finding the proper right ascension. These charts are NOT oriented with north at right like Stardial images. So remember to mentally rotate the chart 90 degrees clockwise so it matches the Stardial images. Or electronically rotate the chart using a graphics program, or print it out and then physically rotate the paper.
