Deep sky photography with the Seestar S50 smart telescope
Photographs below have been taken in a light polluted urban area (Bortle class 7).
They are presented in order of increasing distance from Earth
Note: When writing distances in light years, we avoid using the comma as a thousands separator, as this may confuse readers who use the decimal point instead.
