Hi all: When I first started using cables for my styles I thought a lot about what would be the correct diameter cable. On one hand, I wanted the cable to be as thin as possible, because a thin shadow gives a more precise time reading than a thick one. On the other hand, if the shadow is too thin, it makes for difficult time readings from a distance. Not knowing the resolution formulas that some of you have mentioned, I determined the cable diameter by experimentation.
Since the calculation of arcseconds is a bit complicated, what would help would be some sort of precalculated table which would give the maximum readability distance for different shadow widths. For example, the table might say that a 1/4 inch wide shadow is easily visible from 100 ft. or an 1/8 inch cable is visible from 50 ft. and so on. (These numbers are not correct as this is just an example) I wish one of the dialist/optomologists who answered Ross's question could come up with such a table, with shadow widths of 1/16 in to 1 inch in 1/16th inch increments. Then we wouldn't have to do the calculations. This would be very useful to us. Any takers? (John B? Gordon?) John Carmichael >Good dialing question Ross Caldwell!
