+This panel help you print a [[https://en.wikipedia.org/wiki/Planisphere|planisphere]] with a rotating transparent overlay.
+Before you start you can set the chart options you want, the observatory location (within latitude limit), the color (black on white is suggested), the objects, the labels ("orient to the pole" for better readability in any orientation).
+=== Make the background chart ===
+When ready press the "Set chart" button.

+=== Make the rotating disk ===
+Without changing anything press the "Set overlay" button.

+=== Printing ===
+Use the "Print to bitmap" function to save a large image file for both part. In Printer Setup, select "Bitmap file", set width and height to a comfortable value depending on the size you want to print (something between 2000x2000 to 5000x5000 is a good starting point).
+When asked give a file name for each part.
+If required you can use an image editor to make some adjustment or additions.
+You can now print the background chart on paper or cardboard, and the rotating overlay on printable  transparency film.
+Finally cut the transparency, and perforate both at the marked pole location to mount with a small screw.
