I've done several other large mosaics using APP in the past and was able to do a single integration of all the data channels at once with decent success. MBB did a good job of blending the overlap, and LNC took care of the gradient variability across the different frames. Not perfect, but usable.

I'm attempting to do a 4 panel mosaic of M31 with the QHY600 and Esprit 150 and am not having success in trying to do them all at once. I'm running a new set of integrations that will process each panel separately in RGB and Ha which will then be processed as much as needed to make them ready to integrate into a final mosaic. But this is incredibly time consuming and I'd like to know if there is a way to reduce the workflow.

I've attached the result of my LUM panels being mosaic integrated. This was with LNC 1/3 and MBB, advanced mode normalization.

The data are great and each of the subs are evenly illuminated and exposed so I'll get a good result eventually!

Thanks in advance.
