So sit down, have some coffee, and please join the discussion!. Based in Los Angeles, California we provide a nice area for those who may need a platform to reach out to the astronomy community. For small astronomy related business feel free to make a post including a web link and email. Right now it is simple and basic but if matters change, rules and guidelines will have to be established Astronomy/Telescopes related topics only. Astronomy/Telescope related businesses only. If you are courteous along with using common sense in your posts and replies you should have no problems at all. It only takes a minute. Our observatory is eager to hear comments and suggestions. In order to provide personalized services and access control, you'll need to go through a quick registration, so let's get the conversation started!
