I have the Zwo 120 mms and it works fine. Much better than the earlier models.
If you are using a guide scope there will be no complications.,
If you switch to an OAG the advantage for me is that the MMs has an inner t thread and so will screw directly on to the guider focuser threads and remain solid in the same orientation while shortening the focus path to achieve correct focal distance.
If your DSLR has a hinged rotating screen then the orientation is not so critical .

In the end, with the metro lockdown coming into effect tonight, I decided on the ZWO ASI120MM-S Monochrome, I'll have to live with any deficiencies should they arise.
