Gradients are my biggest concern but hopefully not too noticeable comparable to other issues (background noise) from single images. I get about 25% vignetting which is easy to correct for with flats. Curvature should be almost negligible, the telescope has a corrected field of 55mm and an FX camera only hits 42mm so well within capabilities (theoretically).
I hope to be able to program it to go North to South starting in the West and working my way east. HOPEFULLY with only 120s exposures I'll be able to more or less keep up with it moving across the sky.
