Variable Star Charts created using AAVSO Variable Star Plotter online software.
Each chart is suitable for binoculars, North is up and East is left.
Beta LYR – A beautiful double star, 7.8 magnitude blue secondary; the white primary is a eclipsing binary varying between 3.4 and 4.3 mag every 12.9 days.
Beta Per – Algol, an eclipsing binary that varies from 2.2 to 3.5 magnitude every 2.87 days for 10 hours before returning to 2.2 magnitude.
Delta CEP – The prototype pulsation variable star of it’s class. Varies between 3.6 and 4.3 mag every 5 days and 9 hours. Also a beautiful double with a 6th mag blue companion.
Eta AQL – A bright Cepheid that varies from 4.1 to 5.3 magnitude every 7.2 days
Chi CYG – A long period red giant star varying from 4th or 5th magnitude at brightest to a dim 13 magnitude every 407 days.
Zeta GEM – A bright Cepheid that every 10.2 days falls from 3.7 to 4.1 in 10.2 days
Omicron Cet – MIRA , the prototype of long period red giant variable stars. It takes around 331 days to fall from 3.0 magnitude to 9th magnitud
