Is it possible there could be a large planet, either a gas giant or a super-Earth, somewhere beyond the orbit of Neptune?

Or would a large planet have been spotted by Astonomers already and we'll only find small things out there? I was thinking earlier about how huge the Oort Cloud is supposed to be and wondering if gravity would cause anything to form over time.

This pic was worth the time and money!

So, was thinking of going out and buying a new telescope. I've had this old beginner one for years, still has the computerized stuff and all and doesn't really give good views of much.

I've looked around a bit, and found 3 possible fits so far:
Orion SkyQuest XT8 Classic Dobsonian
Orion 80mm ED Apochromatic Refractor
Orion SkyQuest XT10 Classic Dobsonian

If anyone has had any experience with these three, I'd really appreciate any sort of reviews for these, and other suggestions would be welcome as well. If it helps anyone in forming advice, I would very much enjoy to get some good views of the planets as well as galaxies/nebulae/general deep space objects. Thanks in advance for any help.
