I am looking to buy an advanced telescope for my home observatory, I have a Meade Infinity 70mm Alt-Azimuth Refractor Telescope

but that just does the bare minimum. It does not captune fine moon geography, and Jupiter's a dot. I've got scopes and filters but still, the contrasts for the butterfly nebula and deep sky constellations is not good, compared to what I want to see/have seen in my local planetarium.

So I want to know if anyone here has some experience with professional telescopes, I'd prefer a Schimdt-Cassegrain catadioptric one with a CGEM/GEM mount but as for requirements, I'm in a dilemma.

Does this look like a good one for seeing Saturn with clarity?
