Red Sprites (and Saturn) above Château de Commarque (Dordogne, France)

Red Sprites (and Saturn) above Château de Commarque (Dordogne, France)

Image


After spotting red sprites with the naked eye on a night out at Château de Losse (Dordogne), I went to Château de Commarque in the company of Maxime Villaeys to try and image them!

Red sprites are transient light phenomena that appear as reddish or pink flashes, with ethereal, elongated shapes. They generally appear above thunderclouds, at an altitude of between 50 and 90 kilometres, and are triggered by the intense electrical discharges that occur within thunderclouds (the latter being visible on the horizon in the form of whitish flashes).

That evening, these phenomena were particularly intense due to a large thunderstorm in the south of France, near Perpignan, around 250 km from the Dordogne. Several of them were captured on film that evening, here is the most intense.These phenomena are generally difficult to observe from the ground, as they occur well above storm clouds, and their duration is very short, often only a few milliseconds. They have mainly been documented by observations from aircraft, satellites and high-speed cameras.

This is the first time I've captured one on film, which is why the quality of the image needs to be greatly improved. As this is a very fast phenomenon, you need to use very short exposure times to capture them, as prolonged exposure will tend to erase them.

Note the presence of Saturn above the Sprites, which was very bright that evening.

Don't hesitate! Thanks in advance.

Here you can see three images of the Lagoon nebula in three different types of light, meant to enhance the most interesting structures of the nebula.

First is the Lagoon nebula in broadband + narrowband, which uses narrowband light to supplement the broadband emissions. This is how the human eye would see the nebula and surrounding regions.

Second, is the Lagoon nebula in continuum-subtracted SHO, which only shows the ionized gas in the region. This is how a telescope like Hubble would see this region.

Third is the Lagoon nebula in pure broadband, with the ionized gas emissions removed. This is extremely interesting as it only shows the backgorund stars of the milky way and the reflection areas in the region, both of which are often overlooked.

Crescent Venus Setting Trails
Photo description:
These two images show the difference in the western setting trail of Venus in the northern and southern hemispheres. The one on the left was taken in Taipei at 25.0°N at around 6 pm on July 24, and the one on the right was taken in Sydney at 33.9°S at around 5:30 pm on July 29. That's right, I really came to Sydney! This comparison photo reveals some interesting facts:
1. The difference between the northern and southern hemispheres can be seen from the westward trajectory of Venus, and the latitude of the shooting location can also be judged. Stars fall to the right (north) and down (west) in the northern hemisphere, while stars fall to the left (south) and down (west) in the southern hemisphere. And because of the difference in latitude, the degree of inclination of the two trajectories is also different. Taipei's track is steeper than Sydney's, indicating that Taipei's latitude is relatively low.
2. Venus is only about 10% illuminated recently, so the phase is crescent-shaped. Therefore, the position of the sun can also be judged from the direction of the crescent. The direction of the crescent in the northern hemisphere is lower right, indicating that the sun is northwest of Venus. In the southern hemisphere, the sun is to the southwest of Venus.
3. The color of the sky in the two photos also has an important meaning. It is summer in the northern hemisphere, and the shooting time is 6:00 pm, which is about 40 minutes before sunset in Taipei, so the sky is still very bright blue. However, it is winter in the southern hemisphere, and the shooting time is 5:30 pm, 20 minutes after sunset in Sydney, because at this time, the sky with Venus sinking in the west is already a slightly darker orange after sunset.

Equipment Details:
Canon R7 + SIGMA 60-600mm F4.5-6.3 S DG OS HSM Sports

Post-processing Details:
Using Startrails to stack consecutive shots of Venus into a setting trail, with 5 minutes between each Venus photo. The photo of Taipei on the left was taken from 5:54:28 pm to 6:00:13 pm on July 24th, with a total trajectory of about 6 minutes. The photo of Sydney on the right was taken from 5:24:29 pm to 5:30:14 pm on July 29, with a total trajectory of about 7 minutes.

Location : Taipei, Taiwan and Sydney, Australia

Time: The photo of Taipei on the left was taken from 5:54:28 pm to 6:00:13 pm on July 24th. The photo of Sydney on the right was taken from 5:24:29 pm to 5:30:14 pm on July 29.

ImageVenus - Quarter Phase by Marsha Kirschbaum, on Flickr

Looking west at sunset in the Sierras, venus shown like the moon in its quarter phase. I knew she had phases, but never had the chance to photograph one. I admit this is heavily cropped, with the inset cropped even further so one could actually see Venus more than a bright dot. Taken at 200 mm, F4, 1/25 at 800 ISO. The start of a beautiful evening.

Educational Post, Technical Details:

H alpha 20 sec X 13 Frames Iso 6400
RGB 1 Frames 13 Sec Exposure iso 800
Shot with Canon Eos R astro modified Camera
Using a Fast Lens Sigma Art 14mm of F1.8

Story:
i always enjoyed the night skies, i started astro photography following Robert Gandler Work and learned more about space objects and the frequencies they contained,

Today I teach Astrophotography Workshops with Texas Astronomical Soicety and privet workshops worldwide in Utah califronia USA Iceland and middle east with deepspaceworkshops.

The mission to capture something new that have not captured before is a hard mission, my goal was to capture Aurora and Orion was a hard mission that need the right conditions to align .
Need a no moon night need aurora and I needed clear skies .
I went to Iceland with intentions to capture that frame, knowing if I’ll make both RGB frame and H alpha frame, I’ll be able to get a lot of details from the night skies.

As technology evolves and astro photography filters become more accessible, we can now start to see new combinations of astrophotography from the city or from places never seen before. Combining space objects with northern lights by using one exposure without filter and one exposure with an H alpha filter - without moving the camera, we capture more photons and more frequencies of color enhancement in the right places and document space and time in a more accurate way.

On my oct 25 2022 in Iceland I had the right conditions. The clouds started to clear and I managed to capture Orion and the Aurora with the most detailed shot ever been taking of aurora and orion together thanks to the new filter technology.

Finally I was able to realize this photo, planned and in my mind since years. Every time the bales were moved some days before my planned shot. This year I've done this amazing 4 hours long startrail while I stargazing.
I try to relate thee circles shapes of the srars caused by Earth moving and the same shape of bale. A game of shape in the frame, completed by the vertical Foreground lines, leading our eye to Polar, the startrail's center.
If circles and lines seems to dance together, times aspect is the opposite. The Universe and sky are in continuous movement and expansion while the bales are synonym of a static object, stopped here waiting patiently to be used by the farmers.
When I realize this kind of image, like many people noticed, I inspire to Van Gogh. The starry sky, the use of colors and composition attention recall alway his works.
"I like the night very much, I feel much better at night than during the day, just like the madmen and artists who prefer the night." (Letter to Theo van Gogh, October 23, 1889)

This is indeed a great picture. I love the "timeless" feeling of the "Earth part" of the picture, where a man is resting on a field and contemplating the sky, leaning against a bale of hay. This could indeed have been a scene from the days of Vincent van Gogh.

The sky, by contrast, looks "hyper modern", as people in the past could never have photographed the apparent rotation of the sky this way. Obviously the Earth is not stationary, as it is the rotation of the Earth that causes the illusion of the wheeling of the sky.

Anyway, it is indeed a very striking and beautiful picture! Thank you!

Really thank you Ann
