I want to see the Red Spot and cloud of Jupitar in detail through eyepiece. In order to do that, I have made 6" dobsonian telescope using meade f5 primary mirror. It is good mirror but I can only realise the existance of red spot and cloud with it. I also tried to see the Jupiter through celestron's 11"schmidt - cassegrain at star party, but in fail. Now I am trying to build 16" f4.5 dobsonian using Meade mirror hoping that 16" is enough to gather the light.

Are there anybody who knows what size of aperture is enough to see the red spot and cloud of Jupiter in detail through eyepiece? (I believe there exists some threshold of aperture size to see the Jupitar clearly. )
