Arti??ial Light at Night: State of the Science - darksky.org
...This briefing summarizes the current state of knowledge about how the widespread and growing use of artificial light at night interacts with six key topics: the night sky (Section 1); wildlife and ecology (Section 2); human health (Section 3); public safety (Section 4); energy security and climate change (Section 5); and social justice (Section 6). It also includes a discussion of the emerging ......

Regulating light pollution: More than just the night sky
...Despite these broad effects, the problems of light at night are usually couched in terms of the loss of the night sky in the media, leading the public to believe that light pollution is an issue primarily concerning astronomy and star gazing, rather than being more immediately relevant to the average person through broader adverse effects....

Exposure Time in Celestial Photography ? Celestron
...Repeated exposures of the same starfield allow you to stack the images in the freeware Deep Sky Stacker to reveal even more deep-sky detail. When you use longer exposures, pay attention to the ambient temperature. Heat creates more image noise in long exposures; thus, you can expose longer on a cold winter night than on a warm summer night....

Determining optimal exposure time - Beginning Deep Sky Imaging - Cloudy ...
...The sky is far less washed out despite having a 70% moon (v 0% moon during the 16m stack) and heavy Sydney LP in both. Stars look like they have retained colour better, potentially over-exposed in the 16m stack using 4 minute exposures, and there are a lot less stars visible now too - due to the filter, lack of exposure, or both perhaps?...

Introduction to Astrophotography
...Manually adjust the exposure if necessary. Try "bracketing" your exposures. Take a shot at one or two stops overexposure, and take a couple more at one or two stops underexposure. Faint Stuff Faint astronomical objects in a dark sky can be difficult for the automatic exposure meter in your camera to figure out because the dark night sky is faint....
