Not a good glow when you consider that glow is from a raging river of lava between fissure 8 and the sea at Kapoho. Still it can be pretty under the rising Milky Way. I stayed late at work and took a few photos on the way down the mauna. Click on the image for full scale goodness…
The vog has been thick, really thick. Even here on the west side of the island it is enough that visibility is limited to a few miles, the mountains and ocean are lost in the haze. With the ongoing eruptions on the other side of the island and a lack of wind the vog has enveloped the entire island in gray. At times you can even smell it, the tang of sulfur in the air.
As the crescent moon set this evening it was reddened by the vog. Washed with a ruby red that was reminiscent of an eclipse. This image has been processed for noise and contrast, while the color was unchanged from the raw image. It really looked like this…
Among some slides I recently digitized is a series of astrophotos featuring Orion. Taken in early 1986 this represents one of my early forays into astrophotography. While most of the images are troubled by bad tracking, at least two worked with round, if somewhat overexposed, stars. Judging by the field of view it was a 50mm lens which means it might be an f/1.8, the common nifty-fifty.
The image was most likely taken with my father’s “borrowed” Canon AE-1 35mm camera riding on a small equatorial platform of my own construction. This platform consisted of two disks of acrylic and a small synchronous clock motor. I still have this platform… I wonder if it still runs?
A few thing are quickly revealed when looking at the image. Taken on Ektachrome film the image is heavy on the blue, with poor sensitivity in the deep red. The Orion Nebula shows very little color and less extant than I would expect. The image is also quite grainy, the film grain being quite obvious and distracting. I cleaned up the image a bit in Lightroom, but this is about as good as it gets.
The images was likely a fairly long exposure, perhaps 30 seconds to a couple minutes. I have no records to show how long, no EXIF information on a 35mm slide. The image would have been hand-timed with watch a manual shutter release cable.
Kodak has announced a resumption of Ektachrome production after ceasing all production in 2013. This appears to be in recognition of the remaining, but robust, niche community of film photographers and continued demand for film. First scheduled for 2017 this was delayed into 2018 due to the lack of availability of some materials necessary for production.
Even if the film again becomes available I doubt I will be grabbing a roll for astrophotos. I do have the cameras and lenses available to shoot film. Modern DLSR’s are vastly better at low light.
