The optical tube is really the heart of your night time exploration.  Sizes range from 50mm to 20" in diameter as well as f/ratios from f/2.2 to f/15.  The optical designs range from simple doublet refractors to complex cassegrains with built-in field flatteners.  There is literally something for everyone here, you just have to decide what path you want to walk down.  We are always here to help with any questions you have.
