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