Hi all,
I think its about time I throw away the hair dryer and go for a more sophisticated solution to dew.
What do people recommend for a 12" (f4) astrograph?
1. A controller with 3-4 outputs?
2. Strap for the tube
3. heater for the secondary? (is this necessary?)
4. heater for the eyepiece (eg if I use a barlow)?

I always run my scope off mains power.
