The only advice I can offer is to buy a heated "dew strap".
This is a flexible 'ribbon' containing a heat element that wraps around the telescope at the cell end.
They are pretty common and not too expensive.
I have a Kendrick brand for my MC and it has yet to let me down.
In France try Telescopes Underladen (I hope that's the correct name).
Good luck on your hunt.
