Sample text

The apparent magnitude of a star is the term used to describe how visually bright a star is to the naked eye, regardless of how far away it is from us. You could have a large star very far away or a smaller star close by and they can be similar in magnitude. It is not just stars that have apparent magnitudes. All celestial objects in the sky such as the Sun, Moon, Planets, Nebulae and Galaxies have their brightness determined the same way. These objects however, are not pin-points oflight when seen through binoculars or telescopes, but have a real apparent size in the sky.

The template has been tailor-made for users ofLXD telescopes, where details relating to the mechanics of the telescope, such as alignment or motor problems can be recorded. These notes may prove useful for solving set up problems during later observing sessions. You may wish to dedicate an entire observing session to a single object such as a Planet. In this case you can use observing record templates which have circular discs on them for you to sketch details on. These templates are freely available from the British Astronomical Association.

These templates are freely available from the British Astronomical Association. Youcan produce your own observing template using any word processing package. Alternatively, there are various astronomy computer programs and on-line facilities available on the internet for recording amateur astronomical observations. Their websites are listed in Appendix D.
