I agree. OK below 20 - above is a struggle. Below 10 is great but it has to be pretty cold to reach that (which it often is in canberra). I'd love to cool it 5 degrees or so.
The fan option is certainly a reasonably cheap one and worth considering although the DSI for some reason was made without a fan (Meade say because it doesnt need it I think). Has anyone strapped a fan to a DSI III? Interested in seeing how if there is an easy way - any photos or plans for doing this would be great.
If noone knows I'll try and do a little experiment some time to see if the time lapse helps. Not sure if it reduces the power (and therefore heat) of the ccd. Keeping a controlled temp environment will be the difficulty. I guess if theres not a significant temp difference of a couple of degrees or more theres probably little point. If it does a combination of fan and timelapse could be the way to go.
Cheers
