Telephoto Photography 17Apr13

Between rain showers this morning, I was able to get some spectacular photos from the location of our BMLCam1 on Jonas Ridge, NC.  Both natural and manmade landmarks are readily identifiable.

View looking east showing Brown, Adams, & Hibriten Mountains
Brown Mountain (7 mi away) is the long flat topped ridge in the middle of the image, Adams Mountain (8.8 mi away) is the small domal shaped peak just to the left of Brown Mountain, & Hibriten Mountain (22.5 mi away) is the domal shaped peak on the skyline almost directly above & beyond Adams.  Ripskin Ridge is the dark tree-covered ridge in the foreground.  NC Highway 181, including the Brown Mountain Overlook (seen just to the left of center of the image, 2.1 mi away), follows the backbone of Ripskin Ridge.

Telephoto view of Brown, Adams, & Hibriten Mountains
The left sloping north end of Brown Mountain (7 mi away) is visible in the center of the image, with Adams Mountain (8.8 mi away) immediately behind & to the left of Brown Mountain.  Barely-visible communication towers atop Hibriten Mountain (22.5 mi away) are visible in the distance.  The flat tree covered Little Chestnut Ridge with Forest Service Road 4099 can be seen in the foreground.

View looking east with Brown, Adams, & Hibriten Mountains
A tractor-trailer truck can be seen parked at the Brown Mountain Overlook on NC Highway 181 (2.1 mi away) in the lower left corner of the image.

Communication towers atop Hibriten Mountain (22.5 mi away)
The tall tower on the left is lighted with a flashing white light both day & night.  Compare with night time images previously posted on this blog.

Communication towers atop High Peak (22 mi away)
The tall tower on the left is lighted with a flashing white light both day & night. Compare with night time images previously posted on this blog.

Brown Mountain Overlook on NC Highway 181 (2.1 mi away)
A passengar car, 3 display signs,  & a trash can are visible in the center of the image, while the guard rail along Highway 181 can be seen stretching completely across the image.

Today's photographs clearly show easily identifiable mountain peaks, communication towers, a water tower and the Brown Mountain Overlook on NC Highway 181.  These telephoto- and telescope-assisted images taken from the site of our BMLCam1 on Jonas Ridge conclusivelly demonstrate the sources of some of the man-made lights visible at night from this observation site.  Comparing these images with some of the night time images previously poseted on this blog shows a clear connection.
