[QUOTE="archive10, post: 1015393"] As nice as they are, how does a 90 cm gregorian compare with a good 120cm dish? Is there any x-polarisation benefits or similar that makes it worth dabbling with the smaller sized dishes? My gut feeling is that dish-size is everything, but I could speculate that the gregorian mirror could provide better H/V discrimination or something similar... [/QUOTE]
