thanks Fred, i never really had that much of a problem with dew and never worried about a heater for the ED80 although its a nice scope i wasnt that worried about it dewing up/drying out but the tak is another story.. id really like to keep it dry.
ill be getting heaters for both refractors and a 2" strap for ep's
no reducer yet Ian, the 820mm focal length is something that im really looking forward to but it is on the long list of things to get

i dont think ill see any major problems with the QHY8 but with a 35mm sensor it would probably be a different story, guess ill wait and see.
