A white zone? A great place to take up solar observing!

A white zone is a challenge one needs to conquer.

That's certainly how us urbanites see it. The white zone has the amenities of civilization; the black zone has the beauties of nature. The red zone tries for both and achieves neither.

But it is a practical compromise between affordable housing and access to jobs. My home town of Cambridge has more jobs than residents, but nobody would call it affordable. The black zone has essentially no jobs at all -- else it wouldn't remain free of light pollution.

A white zone is where you cheer when there is a major power outage and all your neighbors are reduced to using candles.

You can read star charts without any aid. When the full Moon smiles at you knowing he isn't the main culpit lighting up the sky.

The White Zone is the top part of the ever present cloud layer covering the Earth. The bottom zone is called the Grey Zone, which we are more familiar with....

Toronto is in the fourth largest white zone in North America. Randy you also have a good point.

Well, I was just out for a couple of hours in the Toronto white zone. SQM 18.35. One purpose of my night was to measure the faintest star I could see near the zenith. I made a thread about it a moment ago here in General if you want the methodology. The skinny is that I could get to 12.6 with steady vision in my 6" Mak Newt and I caught a 12.9 star with averted vision.

For more perspective, I could not see M35 at all in my 50mm finder, little NGC 2158 the fainter open cluster beside M35 was completely invisible in the 6". The great M42 in Orion only showed the central part -the ' fishes mouth'. I tried for M1 and only got the barest hint of it with averted vision.
No filters, BTW....

Much can be accomplished in White zones with judicious choice of targets and some good filters.
