I think its still the STX16803. Probably to do with the size of the filters needed for 16803 chip. They need to be 50mm square or in STX case 65mm square to give room for the autoguiding chip. STXL is essentially the same as STX, the main difference is the self guiding chip is in the filter wheel:

It would have been a plus if STXL16803 could have been made to reduce the cost difference of the 65mm filters versus 50mm filters x 7 filters is considerable. Its like the marketing edge QSI have by being able to use 25mm filters instead of 36mm with others with the QSI 583/683.
