Some VCAS members traveled to the Chuchupate ranger station to observe the peak of the Perseid meteor shower on Aug 12.
There was a HUGE crowd. Cars arriving after me had to park along the road. The lot was full by 7:15pm.
My first photo of the evening shown below just happened to catch a meteor.
Most of the early evening was used to talk with the many families attending about VCAS and show them globular clusters, nebula, Saturn and later Jupiter.
I was glad to have brought along a 150mm f5 refractor.
About 1:30 am the crowd was mostly gone and I started near continuous 20 sec exposures with an 18mm f3.5 lens.
This gave a 66.25 x 44.85 degree field or about 15% sky coverage but the lens had very distorted stars away from the center.
Shifting my target area to try and chase where I thought the meteors were most prevalent proved fruitless.
Several exposures were discarded because of car lights but I kept 469 or about 156 minutes of sky samples.
Results of the 469 frames:
- Meteors 19 That’s about 4% of frames (all meteors seem to be members of the Perseid group)
- Frames with airplanes 46
- Frames with satellites 75 ... thanks Elon ?
- Frames with glints 2
A glint is a brief singular bright flash never lasts more than a few seconds.
I see them much more often now. Probably satellite solar panels briefly reflecting sunlight at just the right angle.
