"Digital Deep Sky Astrophotography "
By Dave Grennan and Jed Glover.
For many years the 'black art' of high resolution deep sky astrophotography was confined to professional observatories and very advanced amateur
astronomers using very expensive equipment. The advent of consumerised digital cameras has resulted in imaging devices being made available to the general public at
far more reasonable cost. Many of these devices are well suited to taking wonderful images of the night sky and the treasures it beholds. In this this talk, Dave Grennan
and Jed Glover will uncover this revolution in digital deep sky astrophotography and will show how very detailed images of far flung galaxies, clusters, and nebulae can be
recorded using equipment which many amateur astronomers may already possess. Since this revolution began Dave and Jed have worked together to devise techniques which have
enabled them to take such images. During the talk they will discuss the relevant equipment, software and techniques used to produce portraits of many jewels of the night sky.
To conclude they will both present many such images which they have produced over the years.
