I started a big mosaic early this year (As soon as I could get an hour on the target above 40 degrees altitude before the end of astronomical night) and it has turned into a two year project due to the weather.
Now complicated by changing cameras, I will hopefully get some data this time around the sun to restart with the new camera and finish it off next year. Even with 5 minute subs and an an OSC camera, when you want a minimum of 70 GOOD subs per panel, 12 panels or more is suddenly a big job.

With mosaics you want to keep it a bit shorter so you can image the whole mosaic over a few days as things move in the sky and start to rotate.
I have had success doing 2.5 hours per panel and take each panel around the same time each night and same moon conditions. Then they go together nicely.
That's where a relatively fast system and sensitive camera helps a lot.
Also where a large sensor is really helpful.
