I've been experimenting with different combinations of magnification to try to find the optimum settings with my camera and telescope to image Mars.  On this occasion over a long session on the unexpectedly clear night of 6-7 September I used my 2x Barlow with an ADC from midnight until around 1:30am UT before switching to the 4x PowerMate, as using the 2x with an ADC  gave a larger image than using the 2.5x PowerMate.  I also wanted to see if the image would be more detailed than one using the 4x PowerMate.    I've scaled up the slightly smaller 2x and ADC image so that it is the same size as the 4x image to compare the results.
