I have recently bought binocular. I usually left it on the left side of my car backseat that sometimes have warm by the sun. Since, I'm not familiar in the precaution of binocular. Is it okay if my binocular is expose to direct sunlight when not in use?

small amounts of heat wont bother them so much but high will .Also direct light plus heat will destroy them .If you can place them in your trunk where it is a lot cooler.

Mine are always in my trunk! If I'm out and about, I quite often check the Sun for sunspots. I use filters.

A partial eclipse of the sun is occurring tomorrow, Tuesday over Hawaii. I quickly sent out to my friend and her son, the Meade Infinity 70mm refractor. They will project this on to a screen.

 

However, what about heat? What about lens coatings in the exposed Sun? I had not thought about this.  Is there a UV filter than will hinder evolution of IR and heat build-up in the scope for the Infinity series?
