When in Sydney, I’m located quite low at the bottom of a hill near river level. I observe and image with newts in the backyard
The only system that works for me are dew heaters , couldn’t do without them
I previously tried dew shields and fans etc. but my dew heater system allows me to observe and image all night even in a heavy dew ( drips off the OTA )
I guess it’s trial and error and all sites are different
Obviously try a low cost method first
Cheers
