comment Gallery of 'actual images' from space?
Lots of amateur astrophotography can be found here: reddit.com/r/astrophotography

comment Is it difficult to see DSO in your eyepiece?
It depends on a number of things, local light pollution, aperture, eye piece, focal ratio, the size and brightness of the target, ect. There are a number that are visible in 4-6 inch scopes in moderate light pollution, Andromeda and the ring nebula for instance.

comment Alt-Az or Polar?
Are you going with the wedge to start getting into astrophotography? The folks at r/astrophotography on reddit would be able to give you some help with any problems.

comment Alt-Az or Polar?
I'd not really familiar with meade hand set computers but I imagine they have an alignment helper routine built in you can use in either mode. Good luck!

comment Alt-Az or Polar?
Do you mean will you be able to align in alt-az with the wedge installed? If so, probably not.

comment Does the gravity of the planets affect the orbit of other planets in our solar system?
@Dieudonné So what is the cause?

comment How will the recent appearance of a supernova, the closest in 27 years, help reduce the uncertainties in our measurements of dark energy?
Has it really been directly imaged? I didn't think HST had the angular resolution to resolve stars that far away.

comment Why are orbits elliptical instead of circular?
Circular orbits are a special case of elliptical orbits.

comment What can be seen with a 4.5" telescope
A big part of the answer is - What latitude are you at? The Double Cluster in Perseus is an amazing site in a small wide field scope.

comment Is the Jupiter-Sun system considered a binary system of some type?
Since Jupiter-Sun's center of mass lies outside the volume of the Sun, that means that the Sun moves around that center of mass All objects orbit at the barycenter between the two objects, not just Jupiter.

comment Is it possible to measure galactic red shift using consumer telescope equipment?
@astromax I'm looking into tracking mounts capable of the long exposures needed. I'm think you'd also need fairly long focal length, maybe a Maksutov-Cassiagrain like telescope.com/Telescopes/Cassegrain-Telescopes/…
