Posting new threads

First; is your new post already covered?
This site has many threads covering most astronomical and space topics.
To avoid duplicate posts, make sure you've searched thoroughly for the subject which might be covered already.
Your new thread may already be covered under an alternate spelling, or simply under an alternative name or expression.
Duplicate posts will normally be merged, or alternatively, if your post is a duplicate but it is deemed to be important, your post may have a redirected link added to the original main thread;  this is at the discretion of this sites moderators. (A technical issue of merged posts is that your post does not bump up the original thread, ie,  does not appear at the top of sections.)
If in doubt, post into the members Sorting Office or the public Off Topic sections.
