I agree with almost all of this, but I still thing refractors are better for beginners
Yes there's a cost, but there's enough to learn with this hobby and if you can afford the jump up in cost to a refractor, I would recommend that. They are "set and forget", pretty much. If you're jumping into this hobby from terrestrial photography (like I did), then that's one thing you already know and don't have to re-learn
Plus, they tend to give better contrast as well.
It's also easier on guiding performance when your tube is small compared to the light bucket (which catches breezes easier).
Best thing to a reflector is the resolution they can give because of all that extra light *drool*
Just my opinion. Great advice, Alex
