Hello Wolfgang,
I'll explain a little more.
To search exoplanets you need detect a variable intensity from light over star, like a sun eclipse, when the planet cross the star the light intensitivity go down a littel bit. For detect a true pattern of this, you need do a lot of captures with short exposure for example 1500 captures or 2000.
The first observation, each night normally are 300 captures by field. (some times its recomended double capture, because if the sky zone there are satellites, the satellite will broken the capture, to solve this doing a couple captures the after program detect satellite and erase it from final file ....)
When i finish to capture 300 (600) lights i go to another side in sky and start again with anoter field.
Finally with a couples of programs I process all information and it return a light curve from each star in field captured, i study each star light curve searching a potential star to be variable star or exoplanet transit. There are programs that searh it for you and return the potential stars in the field captured.
If the result its irrelevant (no stars potentials), then i search another field next night.
But if there are some potential star, I repeat the observation next night but only in this field all night, to capture 1500 or 2000 lights and verify with more data and details and be able to discart star variable or exoplanets transit false.
For now i do this work whitout mosaic, but this limite the night only a couple field.
The mosaic idea is make the field biggest for expand search possibilities.
That is the reason to do a mosaic 4x4 or 8x2 with 300 captures by field, and i detected that the actual scheduler, do not able to do automatically.
For now, the workarround solution is do less than 100 rows in scheduler queue and when finish, clear and restart with another 100 jobs, like video attached in post before. but this means be in front of scheduler to click on reset and start when finish.
The general Idea its go a full mosaic tour (in the example will be 16 rows in scheduler) and when finish , reset all and start again 300 more times if you have a sequency single capture or 150 more times if the sequency are 2 captures, instead of 4800rows for single captures or 2400 rows for double captures in scheduler.
Thanks again, if you need mor information, post here again.
NOTE: Sorry for my english
