Re: Новая "игрушка" - UNIHEDRON SKY QUALITY METER

Интересные замечания высказали разработчики "игрушки" в феврале этого года.

Цитата:

A reading of greater than 22.0 is unlikely to be recorded and the darkest we've personally experienced is 21.80. It is likely that readings larger than 22.0 might be caused from external blockage of the light sensor like trees/buildings/clouds/operator or mountains.

In 1994 and 1995, I was consulting for the University of Denver's Mt. Evans,
Colorado, observatory. At the time it was the world's highest at 14,200 feet
above sea level. We were doing a site evaluation prior to building a new
observatory on the site.

For evaluating the sky brightness at the site, Dr. R. H. Garstang of the
University of Colorado, Boulder, was consulted. He is one of the world's
experts on light pollution. He made the following determination of the sky
brightness from the Mt. Evans location: with no contribution from artifical
light sources the sky should be 21.8 mag/arc-sec^2 in the "V" band. With the
light from Denver and surrounding area, the sky should be 21.34 mag/arc-sec^2.
Many measurements made with a 60cm telescope and CCD camera over two summers
confirmed the site zenith sky brightness at 21.4 on the best of nights.

Since receiving my SQM, I have measured dark sky sites all over the south west
U.S. and to date the darkest readings that I have got have been in the 21.6 to
21.7 mag. range.

The darkest observatory sites such as Mauna Kea typically have "V" sky
brightness readings of 21.8 to 21.9 mag. From this information, I feel that
there is real reason to question some of the reported dark readings being
reported in the SQM archive.

А если кратко и на русском, то измерения выше 22.00 скорее всего вызваны ошибками наблюдений, т.е. часть света не попала на сенсор.

Исходя из этого небо ГАС ГАО приближается по своему качеству к образцовому.

Всё таки надо замерить САО!

Интересно.

У меня недавно в Баловке пикнуло до 21.64. Может, мешали какие-нибудь объекты, конечно.. Надо будет перепроверить на как можно более открытом участке.
