M51 – The Whirlpool Galaxy (& friend)

I began this with my EOS650D, however broke the USB port at the end of the first night whilst lifting the scope off the mount. It was completed with the EOS1000D, then the output from both combined (with the EOS650D data needing to be scaled down to match the EOS1000D’s lower resolution - I suspect the scaling is out by a fraction of a percent, which has detracted from overall focus).
