During a WAS Member Star Watch on Thursday night, August 12, 2021, at our Barnegat Road Observing Site in the dark New Jersey Pines, club secretary Suzanne Leap captured this bright meteor during the annual Perseid meteor shower. Following the streak upwards and across the sky leads back to the radiant in the constellation Perseus behind the photographer. The background sky shows the cloud-like Milky Way running from Aquila at the top of the frame down into Sagittarius, looking towards the center of our galaxy. Mouseover for labels. Note that RS Ophiuchi is labeled. This star is normally around 11th magnitude, but on August 8, 2021, it experienced an outburst to brighter than magnitude 5. By time this picture was captured, it had dimmed to magnitude 6+ and is currently about magnitude 8.
This image was captured using a Canon EOS 80D digital SLR camera with a Rokinon 16 mm, f/2 lens on a fixed tripod. This is a stack of 60 frames of 6 seconds each for 6 minutes total exposure at f/2, ISO 1000. The meteor, of course, was essentially instantaneous, so it appeared on just a single frame. Advanced astrophotographer Jerry Lodriguss provided processing, using DeepSkyStacker for aligning and stacking, Photoshop for post processing. Click here for a larger version.

Alan Daroff submitted this challenge: He took a snapshot of his
TV screen showing the Summer Milky Way as viewed from Thailand, so the
orientation differs from what we would see at 40°N. Three major planets are in
the TV image, can you find and identify them, and based on their position, can
you tell when the TV image was taken? Here's a
smaller version
(2400 x 1800, 369 KB) and here's the larger
original version
(4032 x 3024, 2.56 MB). Bonus question: Can you identify the bright celestial
object near the right edge of the TV screen? Ignore the room reflections at the bottom
and the right-hand side of the TV screen.
