You're very welcome. I will now delete the "Image extraction failed" message, and this feed should disappear.

I will take a look 😉

The colours of late summer in south West of France #BlueSkyArtShow #Summer #photography

A harvested field under a deep blue sky, with large round hay bales leading toward a small stone village in the distance. The foreground is softly isolated by a shallow depth of field.

Double exposure of a meadow. Nature's lovely riot. #BlueSkyArtShow theme is #Chaos all day Saturday. Link to the feed in comments. #photography #nature #meadow #wildflowers #trees

Double exposure of a meadow running up to woods. Purple, yellow, and lavender flowers in tall grass. Repeated upside down

The lake surface got still on the morning of 8/14, perfect for making a star trail image with reflections! The bright trails on the right are the Pleiades and Hyades, center trails from Perseus. The patch of short streaks are satellites glinting earthshine. There are a few meteors. #astrophotography

colorful star trails circle Polaris. the brighter ones are reflected in a lake. airplane, satellite, and meteor trails brekl the symmetry

Ho Chi Minh City, where chaos has its own traffic rules. Hundreds of trajectories, almost no apparent order, and somehow it flows. #BlueSkyArtShow #Chaos #photography

A busy intersection in Ho Chi Minh City, Vietnam, crowded with motor scooters. Several riders sweep across the foreground while a dense stream of motorcycles fills the street behind them. Narrow, mismatched buildings rise above the traffic, packed with balconies, shop signs, awnings, air conditioners and overhead wires. The scene looks chaotic at first glance, yet the riders move through it with a striking sense of rhythm and coordination.

Thank you Julio The technique is also known as lucky imaging

Chaos, organized by magnetism. Plasma twists, erupts and flows across the solar chromosphere, shaped by forces we can only see through the structures they create. Our star, caught in a restless moment. #BlueSkyArtShow #Chaos #photography [details in Alt-text]

$Captured with a Sony A7S on a TS61EDPH, a 61 mm apochromatic refracting telescope, using a DayStar Quark Chromosphere. The Quark is a very narrow-band H-alpha solar filter centered on the hydrogen-alpha emission line at 656.28 nm, isolating light from the solar chromosphere and revealing filaments, plages and prominences that are largely invisible in ordinary white-light images. The final image combines 500 short exposures, aligned, stacked and reconstructed with my own Python processing code based on torchMFBD, a PyTorch implementation of multi-frame blind deconvolution. MFBD uses information from many differently distorted frames to jointly estimate the underlying solar image and compensate for atmospheric seeing and optical blur. The solar disk and the region outside the limb were processed separately: a restrained treatment preserves detail and contrast across the chromospheric surface, while a much stronger intensity stretch outside the disk reveals the far fainter prominences around the Sun's edge.$

Thank you so much Luis for your kind words

Just to give a sense of scale: Earth is shown here at the correct relative size beside the Sun. Prominences extend several Earth diameters above the solar limb. #SolarImaging #HAlpha #Astrophotography

Close-up H-alpha image of the Sun’s limb with a large solar prominence extending into space. A small image of Earth is placed beside it at the correct relative scale, showing how the prominence spans several Earth diameters. A label notes that the Sun’s diameter is approximately 109 times that of Earth.

1/ Here is the timelapse of the Aug 12 eclipse, created by combining the footage from the two setups that accompanied me throughout this extraordinary adventure. Unfortunately, I am missing the corona and Baily’s beads entirely because of a problem during the totality. #eclipse #astrophotography

Still refining my ultra-narrowband H-alpha solar imaging technique. 500 frames with a Sony A7S + TS61EDPH + Quark Chromosphere. I'm tuning my Python post-processing script around torchMFBD blind deconvolution (github.com/aasensio/tor...) #SolarImaging #HAlpha

$Full-disk view of the Sun imaged in ultra-narrowband hydrogen-alpha light. The orange-red solar disk shows the dense, filamentary texture of the chromosphere across its entire surface, with several bright active regions and small dark filaments. Prominences extend beyond the limb, particularly on the left and lower-right edges. The image was produced from 500 frames captured with a Sony A7S, TS61EDPH refractor and Quark Chromosphere filter, then restored using torchMFBD deconvolution.$

Yes please 👍 Curious to see the results

Kat @quantumkat.bsky.social · 18/08/2026

Yes, precisely the same problem! During the daytime it’s practically impossible to get a proper polar alignment. I had to recenter the Sun three or four times, and near maximum eclipse there wasn’t much left to use as a reference for alignment either.

Late post! My Aug 12 total solar eclipse timelapse from Spain. Frame alignment was a headache, none of my usual tools worked, so I ended up doing it manually before assembling the video. Sony A7S + Quark Chromosphere + TS61EDPH #Eclipse2026 #Astrophotography
