Tech@ZWO A 1.25 inch camera.
The ZWO 1.25 inch range is quite old other than the 220, but that sensor is tiny and I'm unsure of its DSO potential. The 174 is larger but quite old and has large pixels (and the 1.25 version doesn't have usb 3 type speeds due to an older usb 2 socket) and needs a successor with smaller pixels, USB C fast data speed etc etc.
A IMX585 would be a modern update, so would the IMX533 (but maybe a bit more niche?). There are likely other new sensors which can fit the bill, the camera price wise shouldn't infringe on the other ZWO planetary range. One of the benefits of a 1.25 format is you have more control of backfocus adjustment depth for OAG use and inside microfocusers as well as other setups where you need to insert into a scope, something you cannot do with other cameras.
