This is a tricky one to shoot and process, Leo 1 can be seen as the light grey splodge just to the left of Regulus the middle star. You almost have to use some averted vision :-)
It needed another hour or so of data... but it was really cold last night!
Thanks to Greg Parker for the idea.
Below is a single shot that I didn't use due to the obvious. As you can see there is not a hint of Leo 1.
