Questions about this item:

Shopper  besides planets and stars, can you see star clusters, galaxies and nebulae? what would they look like in a telescope like this? my idea would be only able to see the central cores of galaxies but I am just curious.
Andrew R  This scope should provide good views of local planetary bodies and may allow you to view very bright celestial objects. Unfortunately the small aperture of this scope does not provide the light gathering ability necessary for deep sky observations.
