First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
A man is a small thing, and the night is very large and full of wonders.

Quote:Interesting info, George. Is the park status with IDAS based strictly on factual darkness or on such soft matter as future concerns and preservation success?....

Quote:In 2010 I saw a light dome in the east (ESE? probably 30 degrees high but comparable in brightness to zodiacal light - or so it seemed to me). And once, probably around that time, I saw a vertical or near vertical streak of light in the east (straight E?) - very narrow, perhaps 10 degrees high. The light dome was presumably development area illumination or flaring, and the streak (as I learned from the videos you linked) was tower illumination. And around that time (winter 2009-2010) it was difficult to get a room in local motels and there were plenty of trucks on the road, including at night and on occasion actually standing at night in the large (usually closed) parking area on the other side of the road from the Astronomy Field. They kept their lights off though when standing; it was not a bigger problem than the night traffic to the camping ground is in season. All that disappeared by the end of 2010 if I remember. One must assume that there is some residual impact on sky brightness generally, but at least all obviously bothersome aspects of the drilling development in my observation did not last longer than about 10 months in 2010. Just thought I would mention what I remember in this connection.
