Firstly, Uranus and Neptune are planets, not galaxies. But if you are using the term correcly, then even a pair of binoculars will allow you to see these things if you know where to look (in the case of galaxies you need mostly dark skies). Now if you want to know if you can see them WELL as opposed to *just* seeing them, then as others have pointed out, the larger the aperture (diameter of objective lens or mirror) the more you will see. Because of expense reflectors are more suited than refractors >100mm to see these things.

Sure. But one that costs a few hundred dollars will only sees a very small featureless disk for Uranus, an even smaller one for Neptune, and a dim fuzzy patch for a galaxy. Some people like to do that, others are disappointed because they've seen great pictures.
The pictures you see are made by giant telescopes costing millions of dollars, taking a picture over a long period of time (hours for galaxies). The view just looking through the million dollar telescope is much less spectacular.

Depending on the diameter of the objective(front)lens, yes. There is no theoretical limit to the size of lens, so there is in principle no upper limit to the resolving power of a refractor. However, there is always a catch, and in this case it is the upper limit imposed by the weight of the lens itself, which becomes so great that the glass "sags" and it's shape becomes distorted. That is why the largest and most powerful telescopes are of the reflecting type.

they haven't any photos of pluto yet, the hot Horizons probe (the quickest synthetic merchandise ever outfitted, placing a clean international checklist each 2d and stil accelerating) is definitely on its thank you to pluto however the gap it has to commute is so far it extremely is going to nevertheless be around 2020 i think of in the past we get any pictures of pluto. New Horizons gets its exceptional speed from it extremely is ioncontinual which delivers a mushy yet consistent acceleration. The planets Jupiter and Saturn have been visited by utilising Voyager a million and 2 yet no probes have been sent in specific to Uranus and Neptune however the probes took the final photos they might as they went close to(ish) to the planets on their way out of the image voltaic gadget. hyperlink to NASAs very own internet site under.

Yes, but a reflector would be better....especillay for the galaxies. A good rule to follow is the WIDER THE APERTURE (width at opening of the tube), the fainter the objects you can see.

You'll need to get a big one to see distant planets. You might want to get a reflector instead; the bigger reflectors are easier to manage (the tubes aren't as long).

Hi. Yes. Get the best and largest you can afford, or try one at a star party. Look up a local astronomy club.

Yes. Get the biggest objective lens you can, lets in more light. Same applies to binoculars.

F.Y.I. - because of all the jokes they have changed the name of uranus- it is now urrectum

No reason why not, if it is big enough.
