Crossover point for SG vs Atlantis

I’ve gotten my hands on SG Atlantis at last. I’ve already watched the first seven seasons of SG1.

My question is What’s the chronology of the seasons? At what point should I set SG1 aside and watch the first season of Atlantis for everything to make sense?

I noticed several references in SG1 seasons 8 and beyond (last time I watched them all through) to ships and events that I assume feature in Atlantis.

Any fans out there who can suggest a viewing order without spoiling things?

thanks

Pretty much right where you’re at. The finding of the ZPM to send a mission to Atlantis takes place after the season finale of Season 7. From that point, the season’s march hand in hand. So season 1 of Stargate:Atlantis = Season 8 of Stargate:SG-1. Enjoy!

They did a pretty good job of tying the two galaxies together so I would recommend wathcing them in chronological order interspersed.

The only change I would make would be to get the movie Ark of Truth and watch that at the end of S10 and before ///deleted to avoid a spoiler///
