Just a quick question.
Can reflector telescopes show as much detail as refractors?
I've see many planetary photos done on SC telescopes with CCD imagers. They show quite a bit of detail, As in bands of Jupiter and Saturn, also Saturn's rings.
Can Newtonian reflectors perform as well if equipped with an imager and EQ drive or are the optics not up to that of a refractor?

Absolutely they can. Also, note that SC (if you are talking about Schmidt Cassegrain) scopes are reflectors, simply of a different design than Newtonian.

Actually, Schmidt-Cassegrains and Maksutov-Cassegrains and a few other less well-known designs are compound or catadioptric telescopes since they incorporate both refractive and reflective elements. In the case of the SCT, the refractive element is an aspheric lens known as a Schmidt corrector plate that counteracts the coma of the spherical primary mirror.

Thanks for the replys.
The reason I asked is I have a newtonian reflector and I was giving some thought to putting it on a equitorial mount to try some basic astro photography with a CCD imager or camera.
I was not sure of the quality I could expect from a reflector vs a SC or refactor.
I did not want to go through assembling this a then find out it would not work all that well.
