If I remember correctly, this is:
2x red
2x blue
1x green
and 5x lum
All 10min subs.
Had plans for 7hours worth of data but only got the above before it clouded over for the night.

Thanks for the details.
You still did well & I know that processing can be difficult.
That was a QHY9 camera with a cropped frame?
