So the Orion 4.5" has got to
be a step up over that one. Can I see any deep sky objects like Orion Nebula
as an example. What about galaxies??


Hi:

Yes, you'll be able to see quite a few galaxies and other deep sky objects with
a 4.5. The entire Messier list is quite doable with this aperture--I've done
'em all with a 4 inch myself--and you can see many other deep sky objects
besides.

Now, as for how good they will look and how easy they will be to find, that
depends on the condition of your skies with regards to light pollution.
