Wait a minute. Does Char's Counter Attack take place pre or post Zeta?
Char's Counterattack takes place
after Zeta. It is, in fact the
finale for the UC story.
UC is short for Universal Century. The timeline in which the the original gundam series takes place. After finishing the UC timeline they have "reboted" the series several times, each time in an "alternate universe" timeline.
Future Century (FC) - G Gundam (I hate this series
sooooo much)
After Colony (AC) - Gundam Wing (decent series, a mostly for the 12-14 year old crowd)
Cosmic Era (CE) - Gundam SEED (the newest thing, I'm not a fan)
There are a few others but I'm blanking on them at the moment.
In any event, back to the UC timeline. The series were not all actually produced in cronological order. However if you are interested in following the timeline you will want to see them as follows.
Mobile Suit Gundam - the one that started it all. Link already posted above. Set durring the One Year War in the year UC 79 it tells the story of Amuro Ray and the crew of White Base as they fight Char and the Zeon forces.
Zeta Gundam - set in the year UC 87 it is the "sequel" to Mobile Suit Gundam. Amuro and Char play supporting roles and other characters from the first Gundam return but the main chararacter is Kamille Bidan. Very dark in tone, lots of moral ambiguity and some very bad things happen.
ZZ Gundam - I have not seen this series. It is a direct follow-up to Z Gundam which ends with quite a cliff-hanger.
Char's Counterattack - set in UC 93 it is the finale to the storyline begun in Mobile Suit Gundam. Amuro and Char take center stage again for their final showdown.
Other series in the UC timeline include:
Mobile Suit Gundam: 08th MS Team - this story takes place durring the One Year War in UC 79 but has nothing to do with the characters on White Base. Instead it follows a single squad of Federation pilots fighting on earth. A war story told from the eyes of the front-line grunts. I have a soft spot in my heart for this series.
Gundam 0080: War in the Pocket - set at the very end of the One Year War. It takes place on the Libot colony which had tried to stay neutral but the war comes to them. Main character is a kid named Alfred. A real tear-jerker about lost innocence.
Mobile Suit Gundam 0083: Stardust Memory - set in UC 83, the main characters are rookie federation pilot Kou Uraki and Zeon ace Anavel Gato. This series explains the events that took place between the original Gundam and Zeta Gundam that led to the Federation creating the elite Titans unit and giving them such power but otherwise doesn't tie in to the "main" storyline. The action scenes are top-notch.
There are also a couple of other series set in the UC timeline about 100 years following the events of Char's Counterattack, but I have not seen them so I have no comment. Likewise there have been a ton of "side story's" released in manga that fill in little bits and pieces here and there. The franchise has been going for over 25 years now. But the above listing hits most of the highlights.
Hope that helps.
