The Fifth Element
Hi Dennis,
Thanks for your comments. I understand what you refer to “ 5th element “ is. The 4th element on my design will provide a 90degree sweep. I searched for a while for all designs available and came up with this. It is so simple and taken the time to build it was worth it. I think wood would work just as well. The brass bushes don’t know if they are in steel or wood. As a fan of Binoculars, there are a new model of Large Binoculars being imported. They have removable 1.25 eyepieces. I have been invited to see them this Friday and will know more then. Assuming a focal length of 400mm one may vary magnifications from 10X to 80X, will know more Friday.
Best regards Larry Brockman
