WHY "netastrocatalog-announce"?

You may have wondered why all subscribers are automatically subscribed to *two lists* instead of one: the main 'netastrocatalog', plus a separate mailing list called 'netastrocatalog-announce' list? The reason is that the main list ('netastrocatalog@visualdeepsky.org') feeds directly into our searchable Web archive of deep-sky observations! EVERYTHING sent to the main list is intended to be a *deep-sky log*: anything sent to this list, on the other hand, does NOT end up in that Web archive! Instead, the 'netastrocatalog-announce' list is for more "timely" announcements or discussions, not to mention any observing questions we want to share with each other.

WHY JUST DEEP-SKY OBJECTS?

Some folks have also asked in the past why the main 'netastrocatalog' list (and now the Web forms) are designed JUST for deep-sky objects: stars, galaxies, clusters, nebulae... Why not planets, moons, comets, asteroids, zodiacal light, meteors, atmospheric phenomena, the sun?? The answer of course is that these observations ARE welcome! But the IAAC Web archive (and 'netastrocatalog') are focused on being a long- term resource for observers of the *deep-sky* - objects which will "always be there" - as opposed to the more "ephemeral" objects of the solar system. However, we all do more than one kind of observing!! So with that in mind, PLEASE share non-deep-sky observations with us any time! Just be careful to post them to: netastrocatalog-announce@visualdeepsky.org INSTEAD OF the main 'netastrocatalog' address. And if there is enough interest, maybe we can set up a separate 'planetobs' mailing list (complete with Web archive, searching, etc.)? Suggestions welcome.

VARIABLE STARS

Another thing folks may enjoy more of is "informal" variable-star logs. We've had a few of these, but there must be many more casual variable observers out there: people whose logs may not be quite up to AAVSO standards, but who still enjoy viewing interesting variables sometimes? With that in mind, PLEASE NOTE variable star logs *are very welcome* in the IAAC Web archive (and so on the main 'netastrocatalog' list)! To submit one, use the same email and/or Web forms as you would use for any other deep-sky object... And keep them coming! (Note that observations of NOVAE and SUPERNOVAE are not specifically discouraged, although these events are of course more ephemeral...)
