Hi NedS,

AIJ does not currently handle de-rotating images, although as long as the rotation is smooth and less than 1 stellar FWHM from image to image, I expect the apertures will follow your target and comp stars without de-rotating the images. I would guess that image rotation will introduce some level of systematics in your data due to imperfect flat-fields.

The best way to find out if your set-up will do what you want is to jump in and start observing known transits.

The ETD is a great way to find when and where to observed know transits:

Another option is the NASA Exoplanet Archive:

Or my favorite is Eric Jensen's ephemeris predictor, which also includes TESS Objects of Interest:
