Deep-sky observers are often so inspired by what they see that they wish to record it in sketches or photographs. To sketch a deep-sky object, draw a circle representing the field of view. With a soft pencil, mark bright field stars and roughly sketch the object while at the eyepiece. You can refine the sketch later. Note details such as the date, the equipment used, and the seeing conditions. To photograph most deep-sky objects, you need to attach either a conventional camera or a CCD camera to your telescope.
