What is the BAM600?
The BAM600 is a list of 600 observing targets for the Southern Hemisphere, covering all different types of targets and catering to various telescope apertures and observer experience.
How did it come about?
John Bambury is one of the “Core 4” volunteers with 3RF Australia (Three Rivers Foundation in Australia) who do a lot of outreach astronomy. In addition to this 3RF Australia regularly hosts small and large groups of observers from the US to Australia with annual astronomy tours known as The OzSky Star Safari.
As most of the US visitors have a very short observing time down here (8 days per trip), John decided it would be beneficial to them if he put together a comprehensive observing list. Basically he wanted to do something similar to the Herschel 400 for Southern Hemisphere observers and for the US visitors who came to Australia.
John put the list together himself by incorporating several of the known common lists (eg. Messier, Caldwell, etc.), and also added a lot of targets he had observed himself over many years and also by consulting with some of his observing colleagues on some of their favourite targets in each target category, which were not part of the "common" lists.
In 2009 the Astronomical League added the BAM600 target list as a “supplementary list” to their Southern Skies Telescope Club Observing Badge List.
How to Use The List
You can observe the list in whatever way suits you to fit in with your available observing time. Most people will take a couple of years to work through the list.
A good way to start off might be to sort the list and allocate targets to each “planned” observing night based on “best month to observe”, setting your observing program for each night to observe targets rising towards the zenith from the East.
By doing it this way you will always have the targets on your program for the night well placed and you should be able to work through them all systematically.
