DG-1 heater has arrived. That looks so small for such a big mirror OK, I'll give it a go. I think I'll connect it to the mirror, let it cure, then sit the mirror out facing the sky on a dewy night and give it a blast and see what happens - worst case testing.
Wish I could have fitted the DG-2. I'd suggest anyone following this path look for a way to make a new secondary holder into which the DG-2 will fit.

Why would you suggest that, when John has proved it works a treat on
his 12".... you haven't even tested yours yet . You would probably
find a DG2 overkill. Either that or they must stick oversized secondaries
in the GSO's
I've added another feature to the secondary holder.
...Now I can adjust the heat setting easily.
Nice John! I'm on my 3rd secondary (the 2nd with the heater) and this one's NOT going to be astigmatic! When I sent #2 to Mark Harry for testing, he tested it with the heater both on and off to see if it would affect the flatness. It did not. I haven't had to adjust my settings yet, but I'm hoping that I can reach them through the 9v battery hole.
