I try to know the best what I'm going to watch. I classify my first target of observation, based on their transit passage for receiving a maximum height, but also their height above the horizon during the night to avoid areas inaccessible to a zenith dobson. The experience showed me that I spend between one and two hours per target T635, to observe, draw, and write my notes, I am very "chatty" because I wrote two or three pages of notes by object, sometimes more. For cons, I'm not "drawings", but "sketches. " I draw as lines the limits of the isophotes, ie areas of similar brightness, and brightness, opacity or even just as an ordnance map details the contours to materialize the terrain. I add the paper all sorts of information, according to scales developed by Ciel Extreme (see Chapter Publications), and with lots of abbreviations (see corresponding chapter Abbreviations). Of course, the number of clarifications and abbreviations increases with the diameter of the tool I use, as the examples of M 17 to the bezel 80, and M 77 at Dobson 635. All my drawings and notes are recorded, not on loose sheets, but on a spiral notebook of 200 pages. In my view, it avoids the losses, or lost leaves. Do not laugh: the day I write this paper, February 2009, I am in my notebook No. 18!. With these notes and sketches, I have all the data to move to the next step, the drawing. I have plenty of time because nothing stayed in my mind, and everything was down on paper (well, that's what I tried to do . . . ) so I can draw several days, several weeks after my observation, which is sometimes very useful. For example, when I come back two weeks in Namibia, and a whole halo drawing book full of notes, it's a month I need to get to the end!. I begin by halo drawing book on a scrap paper stain the darkest possible, with mine 9H charcoal and then I rub the tip of the stump on the spot, and with that blackened stump that I draw on the map drawing. This avoids having stroke, stripe, contrasting black spot too: I try to stay in the gradient of the observation to the eye. For beaches and extensive low cloud cover, I replace the stump of my finger, for example the outer turns in the example of M 77. For very small and very nebulous contrast, I use charcoals directly mines 2H and 6H or 9H example for a core of bright galaxy stellar front view, or for very, very fine details, the 2H and 4H pencils. Stars are drawn with ink pens with liners, and using the normograph to circle it helps draw out well-round, and a diameter proportional to their magnitude. The best record is, in my view, the stars with a diameter of 0. 5 mm Augme for each magnitude. For bright stars, or m <5 for L80, or m <11 for the T635, I note that brilliance by two cross-shaped rays that mimic the spider crested high school, and whose length is proportional to the brightness of the star. All my drawings are oriented, except in very particular, North up, East left. I also clarify the scale and the constellation. The title of the design details the name of the object, including in several catalogs if necessary, the instrument, the magnification, filters possible, and the date and time in universal time. Finally, the place of observation. . . .
