Mars is a very small target, currently it is only 15" wide, so even at 240x it will only appear as a small disc. In my 20" I have pumped it up to 315x and can just make out some details and a hint of a polar cap.
The images you see are often done as mentioned with lots of frames that are stacked and processed and using very long focal length and barlows.
Patience is often the key as there will be fleeting glimpses of steady air which will suddenly reveal much more detail.

Cheers
