Calculator and explanation of telescope numbers.

Hi guys,

Thought this might be usefull for anyone learning about their telescope: Telescope Maths Calculator

Hi Seanie, Richard Bailey posted a link to it, on the Online Astronomy Association facebook page and suggested it for one of the members trying to calculate the "Dawes resolution limit" for double stars of his scope. It caught my attention as a newbie that has often felt out of his depth when people are talking about the performance of their optical equipment. Hopefully others will find it useful.

Cheers
