My hat goes off to you Dennis. Miraculous! If you want to get serious with this type of work, get yourself one of Custom Scientific's ND spot filters. It has a neutral density spot in the center of the filter that cuts the light transmission by a defined percentage. Actually, it operates similar to a moon filter, but selective. You can then place the dot over a bright star allowing the binary/companion to be easily measured. It will take the guess work out of the equation and provide an accurate reading. Look forward to seeing more of your gargantuan efforts - they don't seise to amaze. Thanks for sharing.
