The Hyperstar III is so fast that all other amateur imaging systems are extremely slow and have very disappointing performance in comparison – and that includes the mini-WASP array as currently configured.

Lots of ways of looking at it but in terms of aperture the C11 has got something like 9 times the collecting area of a Sky 90….. You don’t have nine Sky90s
Nope – there’s actually only one way to look at it – and that’s f# which normalises the aperture to the focal length. So the Hyperstar is 5 times faster than the Sky 90 and 9 times faster than the TS 80s (this is for extended objects like nebulae). So taking the mini-WASP as a whole the Hyperstar is something like 2 and a half times faster. BUT the FOV of each MW camera is about twice the Hyperstar so in the end it’s almost break even between the Hyperstar and the mini-WASP array. If I had an extra imaging scope on the mini-WASP (as designed) then the mini-WASP would just edge ahead of the Hyperstar overall. Nothing beats f# 🙂
