I have a STXL16200 camera with FW8g-STXL filter wheel that I purchased in 2018, and I have decided that it is time to recharge the dessicant. However, I have decided that this is not such an easy task, and before I go any further I want to confirm what I think I am going to have to do. With the filter wheel in place, the eight screws on the front cover of the camera are not accessible, and it looks like I have to remove the filter wheel in order to be able to remove the front cover screws. In order to remove the filter wheel it looks like I have to remove four of the eight filters in order to be able to access all eight of the screws that hold the filter wheel onto the camera. Am I correct in this sequence of steps, or is there a trick that I do not see ?
