I may be 50 years into being qualified in sextant optics, correction and use, but only 5 as a telescope amateur and have a history of good inventions which others make money from. A woman has just paraded my 15-year-old stand up urinal for women on Dragon’s Den! Complete list by request.
Quote:Anyway, I will submit to editors of respected publications the following correction, …’until the day of the Cheshire when the type of primary centre mark I used at f/6 and fl 1200 was reflected at f/4.4 as a large unclear black blob.
