OBSERVING OCCULTATIONS USING VIDEO: A BEGINNER'S GUIDE

The RASNZ Occultation Section has prepared a Manual to assist observers of occultations in the region of Australia, New Zealand and the South Pacific. The intent of this publication is to comprehensively describe how to capture occultations using video.

The project’s aim is to bring together in one place as much information as possible about current video equipment and options, observing practices, occultation techniques and other relevant material. It is intended to be a ”how to” guide for observers new to the field, as well as for more experienced observers who need information about specialised aspects of the use of video in occultation work. Topics covered include: generating, interpreting and using occultation predictions, choosing good observing locations, the use of video versus CCD detectors, low-light video systems (including integrating cameras), suitable telescope systems, timing options, recording devices, techniques for monitoring events, reducing data using Limovie, Tangra and Scanalyzer software, and reporting results.

It is because of the many requests for information we have received over the years that this Manual has been written. It’s aim is to gather as much material as possible into one document. Although intended specifically for observers in New Zealand and Australia (i.e. those using the PAL video system), it still contains material which will be of interest to observers elsewhere.

The Manual has received input from participants at several Trans-Tasman Symposia on Occultations, as well as from a number of senior observers in Australasia. However it is by no means complete and we would like to invite you to download the current Version and give us feedback. Specifically. we would like to receive your feedback on how well the material is presented, areas that are not covered to your satisfaction, and anything else that you feel will help us to make the Manual even more useful.
