NGC1910 and environs in the LMC

Hi
Used the 6 inch f3.6 schmidt newtonian "Cometracker" to capture this in the LMC tonight.
6x10 mins ISO200, UHCS filter, Hutech modded 350D. Hand guided. Processed in IRIS and photoshop. The ground on which the mount sits moves overtime with rain and dry, so polar alingment was off, field rotation was evident on a simple stack, so I used Iris's "3 matching zone (affine transformation) where it picks stars in 3 separate 300x300 pixel zones at edges of images and aligns them, rotating if necessary, thus eliminating field rotation.
