Damn Light Pollution

Hi All

Decided to get out back last night for a couple of hours and do some imaging. This is M45 ..... before and after shots. First image is after stacking RGB files in DSS .... Second image after adjusting in PS CS3. You can see what I have to contend with here. I'm sure there is more data hidden in the mist of light but this is as good as I can get with my processing skills. I will pursue M45 again from my dark sky location.

My lady and I went to a revolving restaurant on the 33rd floor of a Perth building last week for her birthday and as we looked at the view we could clearly see several bright spots amongst the suburban sprawl .... where we live is the second brightest area across to the South East region .... due to car yards, shops, restaurants and highways mainly. At which point she finally realized my frustration over the last 2 years and apologized.

Anyway here are the pics.

I'll see how things go when I move, might not need any filters.
Although a Ha would be handy maybe .....

Sounds like VicPark and surrounds, I feel your pain.
I have the Kwinana industrial strip(BP, BOC, Alcoa etc etc) which washes-out my NE view.

Thanks Gary .... soon to be moving 100kms from Perth and 12kms from nearest small town .... just about right I reckon ! You can see a panorama of my new location in General Forum that I posted a few days back.

East Vic Park MrB ... horrendous skyglow ! I used to live in Orelia so I figure you are Rockingham way from your NE view comment ? In Orelia I had quite dark skies, particularly to the west and south and ofcourse directly overhead. Soon I'll have better !

Yeah Rocko, Point Perron. As you said, West, South and OH are great, tho South is slowly being eaten-up by all the development down that way(Secret Harbour, Golden Bay, Singleton, Mandurah etc etc) and sporting facilities with bright lights.

Moving 100k's from Perth?
Lucky *******!
I'd love to move to the bush, love the country, but I'm a surfer.
Wouldn't mind moving south one day tho, Esperance or something, dark skies and surf... sweet.

Esperance is a nice spot but don't drink the water

I hope you get your wish.

Thanks Glen

Interesting articles .... if only more people were concerned with what we foolish humans are doing to ourselves and our environment. Luckily I'm escaping the city at the end of November, can't wait to see the skies in all their glory.

Cheers

Oooh, looking forward to that issue of NGM, Nov edition still hasn't arrived here tho.
Anyone else a subscriber and noticed that they are often on newsagent shelves days, even weeks, before they're in your letterbox?
Frustrating
Spose it IS close to half the cover price tho

Our Vanishing Night

A new address for the article in NG is:
http://ngm.nationalgeographic.com/20...inkenborg-text

Most city skies have become virtually empty of stars.
By Verlyn Klinkenborg
Photograph by Jim Richardson
If humans were truly at home under the light of the moon and stars, we would go in darkness happily, the midnight world as visible to us as it is to the vast number of nocturnal species on this planet. Instead, we are diurnal creatures, with eyes adapted to living in the sun's light. This is a basic evolutionary fact, even though most of us don't think of ourselves as diurnal beings any more than we think of ourselves as primates or mammals or Earthlings. Yet it's the only way to explain what we've done to the night: We've engineered it to receive us by filling it with light...
