    Is it true that sunspots are not really dark, but they only seem to be as viewed from earth in a telescope?

    Hi Lisa,

    Sunspots appear dark on the solar disk because they are cooler than the surrounding unspotted solar "surface" (photosphere). If you could safely view a sunspot without a telescope, and you can do this with PROPER FILTERS when the spots are very large, they would still appear dark; the darkness of the spots has nothing to do with the telescope, only relative temperature.
