This is Special Publication No. ii, It is hoped that you will find this "Special Effects Booklet" to be of great ad vantage. Mr. David Pguilar has over the past two years, tested and tried many of the special effects listed here. He needs to be congratulated on his fine work. \Vhen a planetarium uses special devices to produce realistic astronomical phenomena, this enhances the visual concepts and therefore it increases learning. The planetarium profession has been growing in complexity each year, and along with it the programs also are more complex. It is hoped that this booklet produced in a form that you may
add to from time to time will be an important part of your planetarium library.

I would like to thank the following people who so generously contributed their time and expertise to participate in this project, John Cotton for keeping me on track with those midnight phone calls from Texas, Don Hall for the postcards saying "Is it ready yet?", and especially Don McDonald for showing me how marvelous special effects can really be.

ABLATION TRAIL ABLATION TRAIL PROJECTOR, depending on its motor speed, can be used either as a passing rocket (1-2 RPM) or a bolide (5-10 RPM). Use a very heavy duty motor to move the projector or else you will get a very jerky motion across the sky_ A Hurst 600 inchounce reversible motor works well.
