The golden yellow glow that has dominated the night for generations is disappearing.
Fishing boats under sodium lamps haunt the Tenakee docksLow pressure sodium has been the standard technology for outdoor lighting for generations. the soft yellow glow is familiar to anyone who has lived in any urban area, coloring lives and countless photographs of the night.
The yellow glow of sodium light has been both celebrated and reviled. While the glow can be attractive in night scenery it also creates inhuman tones in faces and photos of people. Movies have been shot under sodium lights, songs reference the golden glow. Astronomers both professional and amateur prefer the lights as the light can be easily filtered from view.

What is it about online commenting that enables people to make totally racist and insulting comments?
A protest against TMT in Waimea, May 27, 2015This is something I have been seeing all too often in the recent round of local controversies. This is nothing new, we all know and see it if we participate at all in online forums. But I can not just let it slide, I cringe every time.
I make a point of following the pro/anti TMT issue. It is an issue that reveals some of the simmering tensions here in the islands, among those are issues of race and cultural identity.
You cannot reason with zealots. They deify a pile of rocks and worship a mythical past which was in reality a Hobbesian fantasm of violence, disease and poverty. – Richard Johnson Esq. in a Civil Beat comment
I have neglected to include the most egregious comments here, they are just too rude for me to re-post. You will just have to settle for the moderately insulting comments here. Want to see the worst? Just wait for another TMT article in the local press and read the comments.
We have been through weeks of the TMT permit contested case hearings at this point, with no end in sight. I have often kept the live feed in the corner of my computer screen through the day.
An artist concept of TMT at night, with the laser guide star system illuminated.Many of the petitioner’s efforts are well prepared and professional, particularly those from Mauna Kea Anaina Hou. Other are less so, to be expected when the participants are not experienced in legal proceedings.
Other petitioners seem unable or unwilling to understand repeated instructions from the hearing officer. At least most of the grandstanding has settled down as it became apparent that it would not be tolerated in the hearing room and that Judge Amano would evict those who repeatedly disrupted proceedings.
A Celestron FirstScope in need of eyepieces. Time to find a couple inexpensive eyepieces. With the telescope destined for an eight year old girl I really did not expect the eyepieces to live up to any demanding standards. But neither do I want the views to be truly horrible either, it would be nice if the telescope is properly enjoyable.
A set of cheap Chinese eyepiecesThus I went to the source of cheap optics and found a set of Chinese eyepieces on eBay that might just do the job. For $22 they were the right price. The set includes three eyepieces, a 23mm, a 10mm and a 4mm for high power, a nice selection of focal lengths. The right price, but how about image quality?
As the eBay sale is from a US seller the eyepieces arrive in just a few days. Unpacking the eyepieces is the first pleasant surprise… The quality is not bad, metal barrels, decently molded rubber bits, decent looking glass. An ebay sale often a bit of a gamble, but this does not look bad at all.
