Good catch-up this morning, great to see Neil and Glen. Varied conversation as usual.
Thanks for the article on focal ratios and apertures Glen, very interesting read. Will have some fun at challenging some of the statements... well maybe not challenge... just see first hand what the relationships are. I too am surprised by the light lost in a Newtonian. It gives new appreciation for the quality of the mirrors in the larger professional telescopes.
Hope to see everyone again nearer the new moon, maybe a trip to the Pony Club.
