I target shoot daily outdoors. Mostly I shoot leaves off an oak tree off my deck. Being winter, temperatures might be 20 degrees. After 5-10 mins. when I come indoors I wrap my gun and scope in a felt jacket to eliminate condensation. Is this necessary?

Reason I ask this is because when I moved here with my wood shop. I learned the hard way about temperature change, steel and condensation.

I’m not really as concerned for the steel on the gun because I keep it well oiled. My concern is the scope sweating inside. 
‘Does anyone know if this should be a concern of mine?
