Since discovering the world of difference between viewing with Low and High f/numbers my question is...... Given that scope makers have always been a bright bunch, why did it take until somewhere about the 60's-70's for the amateur community to evolve from high f/number scopes to low f/number scopes?
The world of difference between viewing with an expansive wide field low f/number scope and a cluttered and dim high f/number scope, why did the change take so long?
Was it because we had invested so much into our scopes and we were loathed to discount the perceived value of high f/numbered scopes? Why was it that the photographic community, a community so closely aligned with our own understood from the get-go the value of wide field lens? Drawing a ven diagram of the two communities photographic/astronomy many of those members are within the set describing shared membership why was it that astronomy battled with narrow-dark scopes for so very long, much longer than can be reasonably justified via techno lag?
