Both need a coma corrector and Skywatcher have their 2" coma corrector which for about £97 not only corrects the coma across large fields of view on f/4 to f/6 telescopes, but it also provides about 0.911x focal reduction. This makes an f/5 effectively work at f/4.555 and an f/4 effectively work at f/3.644.
