Yes I use the Plus with the 294MM. Normally in Bin 2 mode. Bin 1 creates huge files and also is slow to download the files during imaging ( at least with my setup ). Bin 2 still produces an excellent image on the 294MM Pro - the same as the 294MC Pro ( in my opinion )
You just have to remember to set to Bin 2 in Preview Mode for PA and in the Autorun/Plan Modes - ASI Air always defaults back to Bin 1 on startup
