So with a marketing budget that big, surely they're going to pull out the stops, get the absolute best results out there, to tempt us to splash out our cash on their 20Da and EF-L USM lenses? Here's what I see in that image... - screaming lateral colour around the stars...so much for the EF-L lens! - double stars in the corners from a tracking jump, & field rotation pretty much everywhere...so much for showing us their best shot! - where's the rich crimson nebulosity?... so much for the "enhanced" deep red throughput for astrophotography!
