Thanks for the narrative Mike - sounds like its all coming together for you.
I have no observatory here, but the scope is pretty easy to set up on tiles on the rear patio. Recently invested in a 10m USB extender and can do most things from inside now, which is definitely nice in winter. I prefer sitting under the stars when not too cold, not cloudy, no mossies (hmmm - when does that happen?

)
Have just purchased a FCUSB, so keen to get that going too as you describe. Now I'll need some sort of solenoid setup to pop the Bhatinov mask on and off...
