User keywords, or 'tags', are words added to object records by other users to enhance their discovery. You can add keywords that may be useful in helping others find this object.

We are experimenting with tagging because sometimes museums describe objects in language that is highly specialist and user added keywords are useful in bridging the 'semantic gap' between the language of the museum and that of the user.

Any keywords listed have been added by other users like yourself. You can click on them to use them as search terms to dicover other objects. User tags
Related subjects lists the broad themes that have relevance to the object you are viewing. You can click these themes to see other objects related thematically. Related Subjects

'Autogenerated tags' are a new feature that we are testing. These tags are generated by passing the object record through the OpenCalais service from Reuters. This service makes a 'best guess' at the names, places, companies and specialist terminolgy that is in the text of the object records.

By clicking on a tag you can find all other collection records related to that person, place or company.

Because the tags are autogenerated there are likely to be some errors. If you spot one of these then please flag the tag for deletion by clicking the 'x'. Auto-generated tags: [Beta]

The Australian National Antarctic Reseach Expeditions (ANARE) all-sky camera had been designed and manufactured for use at ANARE stations At Mawson base, onMacquarie island and at Melbourne, Hobart and Camden.
Sought by the Museum's Director in January 1960 as an example of Australian scientific progress. In June 1960 an all-sky camera mirror, was loaned to the Museum (L947). Following on from the rationalisation of the Museum's stores and the resolution of the status of early loans, it was decided to recommend the acquisition of the mirror for the Museum's permanent collections.

The surface finish is a form of anodising done by the Defence Standards Laboratories, Maribyrnong. The underside of the mirror's rim has a thread finish for screwing the mirror onto the camera.

Made: 1955 - 1960
