It's all done! For the test, I started with a room temperature of 10.5 degrees, whils the inside of the scope was 12.6 degrees. From the flick of the switch it took 35 minutes to bring the mirror down to 10.5 degrees.
I am happy now, except that now I have it all working, its new moon and overcast....
Typical..
Ah well, time for lots of other improvements around the observatory. My chair needs recovering.....
