Anatomy of the Microscope - The Concept of Magnification - magnifying power
The home to all amateur astronomers & telescopes! Feel free to discuss anything astronomical here, from what sort of telescope you should get, stargazing tips and tricks, to how to use that scope of yours that's been sitting around! Astrophotography is permitted as well, but feel free to check out /r/astrophotography for more of that. If you're looking for your first telescope, please read the stickied post and check out the review/buying guide links in the sidebar before posting.
