Sagittarius Region

Pentax 67 with 200mm f/4 @ f/5.6

60 minute exposure on Fuji Acros. Standard development in XTOL.

Exposure June 19, 2012 12:38-1:38 AM EDT

I noted the conditions during the recording of this image in my notes

"Clear, with threat of fog. Transparency average becoming poor by end of run. I continued as stars were dimmed, but not condensed."

"A very bright night for New Moon, due to high haze and auroral glow combined."

Sky Quality Meter reading confirmed this as conditions were rather poor for this site. Readings ranged from 21.2 to 21.06 from the beginning of the exposure to the end.

Regardless of the poor night, I was happy with how the camera,lens and my tired body dealt with it. I stuck with it.

Nice image.

A couple of times last season, I noticed SQM-L readings around 21.0 and wondered at first what the cause was. Only later did I realize that it might be natural aurora rather than some new source of light pollution.

Perhaps a lot of people are lost in the sky coverage with the 6x7 @ 200mm?
I was having fun swimming through the high res.
Great image again.

Yes, the opposite of "crop factor" with the 67.

Sky glow has been getting more profound as solar activity has been very active. Very noticeable since 2008 when skies were much darker. Really.

How I wish for those dark nights back then Jim. It was so noticeable by comparison with the naked eye. Once I get into the image I find I don't really miss the colour. So much to explore with B&W.

The black and white allows one to wander into star clouds and dark nebulae and appreciate their own innate qualities. Less is more?

I keep telling my wife that Jim - but she ain't buying it. (:
