Nathaniel Everett Green: artist and astronomer ... Richard McKim

N. E. Green, a well-known BAA member from the decade of the 1890s, managed to successfully combine his hobby with his profession as a landscape artist and art teacher. One-time drawing master to Queen Victoria, and exhibitor at the Royal Academy, Green became equally famous for his beautiful and realistic drawings of the planets, above all for his expedition to Madeira in 1877 to observe the perihelic opposition of Mars. He inevitably became an important figure in the early martian 'canal debate'. Green was an Original Member of the BAA who twice directed the early Saturn Section, and ultimately served as President in 1896-'98. In this paper Green's life and works are reviewed, together with new details of his instruments and his approach to painting and drawing. Opportunity has been taken to publish some more of his original work, in colour, for the very first time. (11pp) Image-intensified video meteor observations and MetRec
S. J. Evans Experiences of analysing image-intensified video meteor observations with automatic recognition and analysis software are described. These may be of interest to others contemplating involvement in this method of meteor observation. (4pp)
An introduction to astrometry

Despite advances in photographic emulsions and the rapid evolution of CCD cameras, drawing is still a valid and enjoyable method of recording the appearance of deep-sky objects. It is cheap, simple and most importantly, you do not have to be a great artist to make a permanent record of what you observe. The eye and brain combination is a very sophisticated light detector, with the ability to record detail over a wide range of intensity. This means that both faint and bright detail can be seen together ( for example the bright core and faint outer arms of a spiral galaxy. This is something that other forms of imaging often struggle to achieve.
