Comet PANSTARRS hovers in the twilight above the many moonlit dishes of the VLA radio telescope.
I shot this earlier this evening, on Sunday, March 17, on an evening trek out to the VLA (Very Large Array) near Socorro, New Mexico. Light from the nearly quarter Moon high in the sky illuminates the landscape and rims the 27 dishes of the VLA, the radio telescope that has starred in many movies over the years. The comet appears in deep twilight, here with the colours accentuated. Fortunately, the array was arranged in its most compact formation – at times the dishes can be spread out over many miles.
For this shot I took two exposures moments apart: one tracked for 25 seconds for the sky and comet to ensure pinpoint stars, and one untracked for 50 seconds for the ground, to ensure sharp ground detail. I combined them in Photoshop. I used the iPad app Photographer’s Ephemeris to seek out the location, on Highway 52, the public highway leading to the entrance road for the VLA. Lights from cars on the main Highway 60 across the high Plains of San Agustin streak at right.
The comet is becoming more photogenic as it climbs higher, despite the waxing Moon. A classic curving dust tail is now obvious in photos, though here I had the advantage of a very clear sky at a high altitude desert site. Viewing condition don’t get any better than this. Still, this comet will bear watching and shooting over the next month, no matter where you are in the northern hemisphere.
