Started my first astro shots recently. Running into some dew issues on the lens.
Other than checking the lens and cleaning with lens wipe, I was trying to figure out lens heaters. I would be using kit zoom, 50mm 1.8, 16-35 2.8, maybe my 70-200 4.
I may not have a car nearby to give the heater power, so a more portable solution would be nice.
thanks for your tips.
