Hemi,
I've built and used many Newtonian's over the years - from a 6" f8 (back in 1966) through 18" Dobbies and almost every aperture in between.
I used a great 12" f5 for many years, visually searching for Super Novae.
I feel the "sweet spot" for a Newtonian is a 10" aperture, and around f6 (easy on the eyepiece)
