From what I'm reading the difference between the two is the direction of the 2nd reflector ( concave V convex ). I'm also reading that for offset dishes the curve is inward facing and therefore Gregorian. For prime focus dishes the curve is outward (Cassegrain). Can anyone discuss this ? and perhaps (if it's accurate) explain why offset dishes need an inward facing curve and primes an outward ?
