    The form I use goes:
    
     1 Day and Date (local)
     2 Body
     3 Observed Watch Time
     4 Watch Correction (+Slow, -Fast)
     5 Standard Time
     6 Time Zone (+West -East)
     7 GMT (h m s) - check GMT date!
     8 GMT (Degrees & Minutes)
     9 GHA or (GHA-GMT) of body
    10 SHA of star
    11GHA (Sum)
    12 DR Longitude (+East - West)
    13 LHA
    14 DR Latitude
    15 Declination
    16 (column for adding up results of sight reduction)
    17 Latitude~Declination
    18 Computed Altitude
    
    19 Sextant Altitude
    20 Dip
    21 Sextant Correction (-On, + Off Arc)
    22 Apparent Altitude
    23 Altitude Corrrection
    24 Observed Altitude
    
    25 Intercept
    26 Azimuth
    
    As you can see, it is a little bit 'CN for Dummies' as someone asked for. There
    is none of that Ho and Hs stuff, its mostly in plain language.To use with it I
    have one page of instructions that walk you through the process step by step
    with a Time/Degrees conversion table on the other side. This sheet is covered in
    plastic as it gets used all the time and makes a handy bookmark. Everything else
    I need is in one slim hardcover book that lies open flat - sight reduction,
    examples, almanac, prediction and indentification, star finder, detailed
    instructions for everything from noon sights to finding amplitude to finding
    latitude via Polaris to averaging sights, 3 different methods for calculating
    azimuth and all sorts of other forms that can be photocopied. There is space for
    4 bodies on one sheet, 8 if printed on both sides.

    I keep referring back to the form to check, for example, the + and - when
    converting local time to GMT and vice versa. This form can be used with other
    sight reduction methods, its just a handy way of laying out the process step by
    step. It must be great to know and understand the whole process so well you can
    carry it all in your head, but I'm not quite there yet.
