Mirror took over 12 months from start to finish - but the results were impressive. The society aims to create mirrors of better than lamba/8 surface aboration. https://www.broughastronomy.co.uk/apps/photos/photo?photoID=102706491 102706491 15m eXperimental Development Model (XDM Extract from website: "Karoo Array Telescope (KAT) will be used to test technology leading up to development of the Square Kilometer Array (SKA). The XDM is a testbed prototype for KAT.

Taken at about 21:00 while waiting for the Lunar eclipse, bright full moon. 59 photos of 30 seconds each, ISO400, F8, 28-135mm lens set to 28mm. Images stacked with a small program called star trials. With one of the 59 photos Reynardt used a spotlight to illuminate the surroundings, especially the wind turbine - very effective. https://www.broughastronomy.co.uk/apps/photos/photo?photoID=129513403 129513403 Startrails - Album Cover See full size image in album https://www.broughastronomy.co.uk/apps/photos/photo?photoID=129514028 129514028 Milky Way from Jo'burg Pat Kuehn August 2011 - "I have taken a new sequence of shots of the centre of the milky way during August.
