I want this in a 1.25 inch body, so it'll be good for OAG use and solar imaging too. The 174 is way too old now and the 1.25 inch line needs a new 1.25 larger sensor model, even an IMX533 would be good in a 1.25 inch camera body format. The question is how long will ZWO take to respond to the likes of existing products from QHY and Player One. Either do this or unlock the asiair to use competitor cameras.
I'd estimate if it's being worked on right now, a demo ready for NEAF 2025, then summer release. As competitor products are already available to buy right now, they can't take too long to bring to market.
