A sketch of the crater Bailly by Harry Roberts, on display at Cork Castle, Ireland Harold Hill, the great lunar draftsman, says of Bailly “There is so much sketchable detail within this formation that it is well nigh impossible to cover Bailly in its entirety on a good night.” For this reason I was only able to record the southern half in 2004.

What does an amateur astronomer do? Les goes hunting for galaxies

January 23, 2009

Nick Lomb
The globular cluster 47 Tucanae was one of the objects Les and his fellow amateur astronomers looked at observing from Bargo 28 - 29 December 2008, though they probably had a much better view. This is an image from the now decommissioned Sydney Observatory Robotic Telescope that used to be on the roof of the Powerhouse Museum.
