Right Angle Sweep, (RAS) or Be Your Own GoTo
By
Tom Hoffelder
Comments from Dick
Parker, on using the Right Angle Sweep.
"Tom explained this right angle
sweep method to me and after less than an hour I was able to find many new
objects with ease. And by using this method I have started to learn the various
names of the stars in each constellation which adds to my appreciation and
overall knowledge of the sky. I had been using setting circles to find objects
directly by coordinates, but have found Tom's method easier and much more
reliable especially with portable equipment used at varied observing sites. I
recommend that you give it a try and we should all thank Tom for freely sharing
with us the tables and references that obviously took him many hours to
assemble."
