Variable Stars

Variable star observing is different from Deep Sky observing. Dave Sworin has written in 1997 a very interesting text about this subject. The article is no more available on Internet, but Sworin pointed out :
- First observation of Deep sky object is great thrill. Deep sky observing is an experience in space dimension.
- Variable stars are less impressive, but more interesting the more you observe them. The dimension of variable star observing is time.
- Variable star observation heals aperture fever.
- Variable stars are not bothered as much by light pollution.
- You need an organization. (AAVSO, CBA)

Publications

Here are the final results of observations, i.e. publications

PowerPoint Presentations

Variable stars are not well known by amateur observers. I am trying to fill this gap by presentations given in local astronomer clubs. I hope that these presentations will convince amateurs to start Variable Star observations. These PowerPoint presentations were given in French. Do not hesitate to use them.
