These are all amateur observatories, some home made, some manufactured small backyard obervatories.
The scope is an LX-200 Meade Instruments 10" diameter, Schmidt Cassegrain. Mounts need to be strong, if one plans on conducting astro photography or CCD imaging. Some mounts are metal pipes filled with fine sand to help eliminate sound vibrations, some are concrete. My observatory is in the early stages of building, as I only have limited time to build. But should be done by summer.
