Extractions: LX-90 8" f/3.3 - 18 minutes (stack) - ST-237 - Bayside, NY. This photo is from my house in eastern Queens, less than 10 miles from Manhattan. The western sky glows bright orange from the city and the entire sky is blue-ish from surrounding lights. I took this exposure while M1 was towards the "darkest" part of the sky, but sky glow was still a major issue, even after processing not all of the gradient could be removed without losing detail in the nebula. LX-90 8" f/3.3 - 14 minutes (stack) - ST-237 - Southold, NY. This photo is from Custer Observatory on eastern Long Island, a reasonably dark site on the north fork, surrounded by vineyards and homes. It's located about 80 miles from my house and is about a two hour drive. Wind was a factor in this photo, but you can clearly see the advantage of going to a dark site. Processing is minimal in both photos, dark frames subtracted, levels adjusted in Maxim/DL, cropped and usm in Photoshop CS2.

Extractions: Light Pollution and Astronomy By far the biggest problem facing amateur and professional astronomers is excess light. The reason observatories are built in remote areas is to get away from obtrusive lighting, smog and other bad "seeing" conditions, astronomers are not anti-social. A lot of planning must go into site selection to take advantage of the clear steady air in unpopulated areas. It is useless to build a facility that costs millions of dollars only to have its useful life cut short by the growth of a new city. For amateur astronomers the problem of light pollution becomes a nightmare. Light from shops, sports grounds and yard lighting limit, if not end totally, the usefulness of the "backyard observatory". Apart from the simple pleasure of looking at the night sky, the work of some amateurs supplements the work of professionals. These amateurs should be regarded as unpaid professional observers. The main function of a telescope is to amplify light from distant objects, as these objects are very faint. Stray light has the effect of washing out the contrast and reducing the image quality. If you turn up the brightness on your TV you can simulate the effect. The higher the brightness the more the image deteriorates. For an astronomer, that light YOU leave on in the back yard, or those flood lights in the driveway, can mean the end to any chance of using a telescope on all but the brightest of objects.

Extractions: You are in: Home Environment and planning Pollution Light pollution From April 2006 the nuisance provisions of the Environmental Protection Act 1990 have been extended by the Clean Neighbourhoods and Environment Act to cover artificial light emitted from premises (excluding transport facilities, freight depots, lighthouses, defence premises and prisons). Abatement notices can be served by the Council if light, for example from domestic security lights, is causing a nuisance. For light to be a nuisance it would have to materially affect someone's use of their home, or their health, based on average sensibilities. On receipt of complaints about nuisance lighting, we will contact the owner of the light to suggest that they contact the occupiers of neighbouring properties to ensure that lighting on their premises is not causing a disturbance. Complainants are advised to keep a record of the times and the duration of alleged nuisance should they wish to pursue the matter further. If problems are not resolved an officer will investigate whether, in their opinion, the light is causing a nuisance. For more information see Statutory Nuisance.

Extractions: Jump to: navigation search Salt Lake City from the air Photo by Brian Jolley Light pollution is the light that escapes upwards or side-wards from means of illumination at night. The normal usage is light that causes the viewer's eyes to be desensitised to the light from the stars and other cosmic sources. However, 'trespass' can also occur when a neighbour's light gets into another's property when it is not wanted. Unwanted light can disrupt ecosystems , cause adverse health effects, obscure stars to city dwellers, interfere with astronomical observatories , waste energy , and fade curtains (the same as daylight saving Light pollution is the junk that visible light photons have the nerve to throw into the sky. It is the natural predator of the dark sky . Light pollution is noticeable in densely populated areas that have bright, uncovered lights. If you can't see the stars at night because the neighbor's porch light is shining in your eyes, that's light pollution. They may say it's for safety, but they aren't safer, and you can't see the stars. Light pollution annoys astronomers and robs much of Earth's population of the opportunity to enjoy the night sky . Light pollution is also a threat to wildlife. All species of sea turtles native to Florida waters are listed as either threatened or endangered, and according to the

Extractions: Light Pollution At the beginning of the 21 st century, humanity is losing a valuable and beautiful part of its heritage. For the first time in history, poorly designed and badly aimed lighting is denying vast numbers of humanity a view of the night sky. Urban sky glow now pollutes nearly all of Britain's night skies. As amateur astronomers we have a responsibility to guard our night time environment against light pollution. What is light pollution? Light pollution is the popular name for sky glow - a brightening of the night sky caused by the scattering of artificial light by aerosol particles (e.g. water droplets) and dust in the air. What causes light pollution? Artificial light gets up into the sky in two ways. By far the greater proportion of upward light arises because the design or installation of many light fittings allows a significant fraction of the light produced to be emitted above the horizontal, so it goes up into the sky - this is the direct upward light. A much smaller proportion is upward light is reflected upwards from roads, pavements and buildings - this is the indirect upward light. The following image of the Earth at night compiled by NASA from various spacecraft missions shows the extent of light pollution across the whole world: few areas of our planet are visibly dark at night!

Light pollution is sometimes said to be an undesirable byproduct of our industrialized civilization. Light pollution is a broad term that refers to multiple problems, all of which are caused by inefficient, annoying, or arguably unnecessary use of artificial light. Specific types of light pollution include light trespass over-illumination , and sky glow Where is light pollution found? The now-classic Earth at Night composite image (left) suggests that light pollution is a problem in many parts of the world, with the worst concentration of light pollution being found in urbanized areas. In the highly industrialized and populated areas such as many parts of Europe, Asia, and North America, light pollution is a real problem. For example, in the Eastern United States, there are many areas where large expanses of land are illuminated at night. As cities and suburban areas grow, the number of lights at night also increases. Why do we care about light pollution? Light pollution is a strong indicator of wasted energy. Lights, contrast, and glare all impact the

Although this article was written specifically about the city of Charlotte, it is not just a local problem that only affects Charlotte. It is a problem that is common to ALL major metropolitan centers, and that is why we have elected to reprint this article here. Section: VIEWPOINT By DANIEL B. CATON, Special to The Observer Imagine a National Park where we permitted the scenic views to be needlessly polluted with man-made refuse to the point where we could only barely see the most prominent features. Subtle valleys and glades are filled to the brim, with only the greatest peaks rising above a sea of litter. Suppose further that this trashing of the environment was not intentional, but allowed to advance even though the alternative is less costly and would save other natural resources.

A short page explaining how lighting can be made to reduce the astronomical effects of pollution by Manchester Astronomical Society.
http://www.mikeoates.org/mas/light_pollution.htm

Extractions: In association with the Manchester Astronomical Society As we approach the millenium, most amateur astronomers are acutely aware of the problems of light pollution and the difficulties associated with observing the night sky in heavily populated areas. They also probably feel that things will only get worse. Light pollution is a rather all-encompassing expression describing the light which hinders observation. It has several sources, including natural ones such as the light generated by the bombardment of the upper atmosphere by solar radiation. However, the most pervasive source of light pollution is the glare associated with the street lighting in built up areas. Short of moving house, there is little the individual urban amateur astronomer can do to eliminate this problem. There is some hope, however. Filtering the light pollution and viewing only the wavelengths of light of interest is one way of achieving good results. A recent lecture at Manchester Astronomical Society illustrated the manufacturing technology which is used to make filters to reject the unwanted light. This brief paper describes the efforts under way in Manchester to make routine light pollution filtering a realistic goal.
