I can see few good advices already and wanted to add a comment on your initial comment related to OAG

If you want to have OAG please check the backfocus beforehand. I believe QSI is the only CCD with built in OAG and any other CCD will requite an external OAG which will take some additional backfocus.

TEC flatteners have about 78-85 mm backfocus which leaves little or no space to fit a OAG after the flattener.
