Yes I own a 16200A and the 50mm filter wheel. I like the sensor also. The filter wheel works nicely, the butterfly shutter does not leave any artefacts. It is a relatively light combination for your scope. Sensor is pretty clean looking. I haven't done as much imaging as I would like though. I also looked at the ATIK version but was particularly concerned about reported shutter issues in some of their products.
