DIY dew heaters / dew straps for telescopes, lenses, eyepieces etc. in astronomy, astrophotography and indeed photography. I also delve into the other options in the battle against dew formation, such as the dew shield and the primary mirror fan.
Instead of buying a £15 - £20 dew heater, I bought £5 worth of resistors and can make at least 2 or 3 dew straps from these.
If you feel I've saved you enough to earn it, you might consider buying me a coffee? : https://buymeacoffee.com/cheapasstro
