The Best Times for Stargazing in Lemon Grove

Expert Tips for Lemon Grove Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Lemon Grove, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the CA region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Palomar Observatory (43.7 miles away) remains the benchmark for regional sky quality.

"Power pole blocks sky to southwest but otherwise good view of both San Diego and Los Angeles area to the horizon. Light reflects off 60 inch dome causing some bias, but tree blocks much of the eastern sky so should balance. Evening very clear at sundown, some few high clouds far west. By 3rd data set clouds in western sky significant, L.A. lights reflect off them increasing light dome reading. 4th data set many clouds in western sky. No part of the sky is truly dark, cresent-half moonlight levels illuminate land, Milky Way barely visible at end of astronomical twilight, disappears in San Diego light dome to south in Canis Major and L.A. light dome in Cassiopeia."
