I used a short tube 114mm reflector from K-mart for over a decade. I saw a lot with this scope including detail on Jupiter, Saturn and Mars. I found both Uranus and Neptune with it and frequently observed nebula (orion, eta and tarantula) and open and globular clusters with it.
I also did prime focus and eyepiece projection of the Moon and did piggyback photography of constellations.
On day I tried removing the built-in barlow/corrector in the hope it would give a cleaner light path. The spherical aberation was so shocking I could barely see a thing.
You can see a lot with these scopes and they are very portable. It's just a shame that that cheap corrector must remain in place
