A night image of a lunar eclipse taken in an astronomical observatory. There are four large cylindrical telescope domes and two small rounder ones under the night sky. But the stars aren't point sources: instead, they are curved arcs streaking across the sky. In the middle of the frame there's an arc brighter than the rest. It looks like a Q-tip, with white bright ends and a thinner red middle part. It's the Moon, which starts bright, then fades during the eclipse and finally gets brighter again.

Photo of a page from the symposium proceedings "Celebrating the AAO: Past, Present & Future". The relevant part of the text is as follows: As I releated at [this] meeting, Californian astronomer Sandra Faber told me before I left Keck that, on seeing the Ann plate image projected at an astronomy instrumentation meeting attended by Pat and Graham Bothwell (at MIT?) she knew that a new era in instrumentation had dawned.

Photo of a page from the symposium proceedings "Celebrating the AAO: Past, Present and Future" Text is as follows: 4. On the Ann plate The famous "Ann plate", showing the capabilities of the AAT's computer control system, appear in teh paper by Pat Wallace in this volume. While the photograph is widely remembered, exactly who took it is slightly uncertain, and probably irrelevant. However, for the record: Pat Wallace: I did the experiment and processed the plate, but I think an AAT technician was present in the PF cage for opening and closing the shutter, with me at the telescope controls... I guess it was 1975 [It was 22 December 1974] Peter Gillingham: I don't think it much matters but I'm almost certain Ken Oliver (the first AAT electrician) was the Night Assistant for the night and he was the one in the PF cage. But, as Patrick says, aII he had to do was to open and close the shutter (several times) as Pat commanded. It's also my quite confident recollection that, one or two nights earlier as we (Pat, very likely John Straede, and I) were discussing what should be traced on such a plate and puzzling over what would be a suitable word, Ann Savage, came into the Control Room and, on being acquainted with the topic of conversation, suggested "Ann" right away, pointing out its geometric simplicity [and only two alphabetic characters had to be encoded!].

Photo of a negative print of a photographic plate taken with the Anglo-Australian Telescope. In addition to normal stars (black on a white background, because it's a negative), there are black circles, raster scan patterns, Lissajous figures and the name "Ann" scattered across the image.
