Tonights Observing

16 09 2017

There is obviously much more cloud than earlier forecasts. Intending visitors need to make their own decision whether or not to give it a go.

Observing for Saturday 16th September is ON.

15 09 2017

There will be some cloud early, which will improve to “clear” by 10pm. Visitors are welcome, so do take advantage of a good night’s observing—we have had a terrible run this year. There will be a brisk 24 kph wind so it will be cold—rug up well. As usual, the gate will be open from around sunset.

Solar Observing for Tomorrow September 10th is ON.

9 09 2017

There will be some cloud it should be ok. If you’ve never been to one of our Solar sessions please come along anytime from 11am to 1pm. Prepare to be amazed by this lesser known branch of astronomy. No, it’s not going to burn your eyes, but please bring a dark hood with you to enjoy it to the utmost. Directions are on the NSAS website.

Abstract: Spectroscopic observations of stars and galaxies often show us much more than we can learn from simple images, though they often require significantly longer observations.  One way to make spectroscopy more efficient is to observe many objects at once through a long slit or with numerous independent fibres.  I will describe Starbugs, a robotic optical fibre positioning system that facilitates the observation of hundreds of stars or galaxies simultaneously.  I will also describe the science and engineering of TAIPAN, an instrument currently undergoing commissioning on the UK Schmidt Telescope at Siding Spring Observatory, and the first instrument to make use of the novel Starbug technology.
