What happens if you look at the sun with a telescope?
Viewing direct, unfiltered sunlight (even for an instant) causes permanent, irreversible eye damage including blindness. Do not use a Herschel wedge or projection method when observing the Sun with a nighttime telescope larger than 70mm. Doing so can cause heat buildup inside the telescope, damaging its optics.
