Telescopes do not smoke, what are you talking about. As a kid, I've been burning pretty musch anything using my telescope.

I'm talking about real telescopes...not kids telescopes. If you go to an astronomy forum, such as CloudyNights, you can find stories of people who accidentally ended up pointing their telescopes at the sun. When you have a 6 to 10 inch mirror collecting sunlight, lens coatings on eyepiece lenses melt and burn, and lenses end up cracking from the heat.
