I would do each orientation separately rather than cropping it will go easier on your computer too. you may be able to create a mosaic afterwards. I would choose either the blue or the red rectangles (see attached).

With the sigma clipping, do you set it at 2.00 with 5 iterations? This seems to be the recommended setting, but its the 5 iterations that seems to add a lot of processing time.

I use 2.00 and 5 iterations. it will likely run much faster if there a single orientation.
good luck
