Guidechip image binned 2x2 and dark auto reduced with master dark/bias/flat through the APM/TMB 130/780 APO Refractor.

Notice that the dark obstruction is now gone and the guidechip image is now smooth.

I will use this to guide from now on as it only takes a split second for the reduction to take place after the guide exposure is taken.
