A bit late on this but it seems the 533 has a similar issue to the 294. ZWO are correct do not use bias frames as it seems the bias is not stable on the sensor (if the same issue as 294), use Flats and Dark Flats, and be very careful to match them, plus Dark frames. On the 294 it is suggested using low offset, 4 to 14.
Vignetting is not a particular problem of the RASA. This is my first attempt at the Iris, https://www.astrobin.com/plzzrw/?nc=user
