Big Bear Observatory
Big Bear Solar Observatory (BBSO) is a university-based solar observatory in the United States. It is operated by New Jersey Institute of Technology (NJIT). BBSO has a clear-aperture Goode Solar Telescope (GST), which has no obscuration in the optical train. BBSO is located on the north side of Big Bear Lake in the San Bernardino Mountains of southwestern San Bernardino County, California, approximately east of downtown Los Angeles. The telescopes and instruments at the observatory are designed and employed specifically for studying the activities and phenomena of the Sun. Establishment The observatory location, on Big Bear Lake in the San Bernardino Mountains, was chosen for its combination of high altitude and daytime stabilizing influence of the lake, which were found to be ideal for solar observation. The location at Big Bear Lake is optimal due to the clarity of the sky and the presence of a body of water. The lake has more than a mile of water to the west, which is th ...

Solar Observatory
A solar telescope or a solar observatory is a special-purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far outside, the visible spectrum. Obsolete names for Sun telescopes include heliograph and photoheliograph. Professional Solar telescopes need optics large enough to achieve the best possible Diffraction#Diffraction limit of telescopes, diffraction limit but less so for the associated light-collecting power of other astronomical telescopes. However, recently newer narrower Optical filter, filters and higher framerates have also driven solar telescopes towards photon-starved operations. Both the Daniel K. Inouye Solar Telescope as well as the proposed European Solar Telescope (EST) have larger apertures not only to increase the resolution, but also to increase the light-collecting power. Because solar telescopes operate during the day, seeing is generally worse than for night-time telescopes, because the ground around ...
