HELENSBURGH ASTRONOMICAL SOCIETY
- lux ex astra -
THE sun - our star - solar activity

First a word of Caution:

Observing the sun directly whether with the naked eye, binoculars or a telescope causes instant and irreversible damage to your eye and almost certainly permanent blindness. Please take informed advice before proceeding to observe the Sun. There are methods and instruments available to assist in such observation - the full aperture of any instrument that is pointer at the Sun must be covered with an appropriate solar filter or filter mask combination

Here at this society we make use of White Light binoculars, a Coronado Solar telescope and occasionally Baader AstroSolar[TM] Solar Filter Material from Baader Planetarium - this filter material has been specifically designed and manufactured for use on telescopes and binoculars for observing the sun in white light and is sold at most reputable astronomy shops - do not to use any substitute that may be claimed to 'work'. Children must must not make solar observations unless a responsible knowledgeable adult is supervising at all times.

Please be safe - if in doubt don't proceed!
