   Presently I have a STXL11002 camera with AOX and SBIG FW8S-STXL Standard 8-Position Filter Wheel for 50 mm Round Filters.
   
   If I upgrade to the new Aluma AC4040, will I need to change the filter wheel to the SBIG FW7-STX 7-Position, 50mm square filter wheel or can I still use the filter wheel that I have?

   The sensor in the AC4040 is larger and requires 50mm square filters. I would recommend the FW7-STX or the new AFW-10-SQ5 filter wheel which has 10 slots.
