Improving connection between field flattener and focuser on Sky Watcher Equinox Pro 80mm OTA so that QHY10 camera is not loose/does not fall out

I was very concerned that only one thumb screw on focuser tube for Sky Watcher Equinox Pro 80mm OTA- my QHY10 and field flattener kept becoming loose risking it would all fall out and affecting focus and flats. I was going to drill and tap extra holes for more thumb screws then noticed this hole directly opposite the thumb screw, virtually invisible because it has a grub screw in it. I replaced that with a more robust bolt and now have a very secure connection for my camera that i don’t think will loosen….Just need to take another set of flats now!
