I setup star constellation maps years back for customers that want to add a few constellations to their stunning star ceilings. You can see the Dipper and Crux here in this star constellation how to video. I have PDF files for each of the below constellations which you can take to your local print shop and have them print your constellation maps onto A1 size paper or you can down size the file to A2 (Do not go smaller).
The color coding of my templates simply let you know which size star to fit in which position after you have punched all the holes. From the bright range patch use any of the two largest size stars in the blue holes, 3rd and 4th size stars in the red and any of the remaining smaller size stars for the yellow.
Use around a half inch punch for all the holes which will let you fit all star sizes. You do not have to punch different size holes based on the color as the color is simply a visual after you punch to know which size star to place in any given position. Only one star should go in each position. Have the room correctly dark and enjoy your astronomically correct star constellations within your star field!
Note: Use no more than a few of the bright range stars for star constellations as they are very important to also be placed random thru out your star ceiling. If using all stars as random just follow my video instructions on the XVR star page. Approaching two decades of creating star ceilings I found that most customers do not set these up as random constellation style groups will naturally occur without you trying to set them up.
