First time I combined focus bracketing/stacking and HDR. I needed HDR obviously to deal with the brightness levels. At the same time, I wanted to have the bulb interiour completely sharp, but the background should be as blurry as possible. So I had to open the aperture to F2.8 and shoot 15 shots (stepping 1). I did 5 brackets with 2EV difference. Post processing was to stack the 5 brackets (Helicon Focus method C) and then merge the HDR in Lightroom. Some global and local adjustments in LR as well.
NASA's Solar Dynamics Observatory came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that float above the sun, tethered to it by magnetic forces. They are usually elongated and uneven strands. Only a handful of times before have we seen one shaped like a circle. The black area to the left of the brighter active region is a coronal hole, a magnetically open region of the sun. While it may have no major scientific value, it is noteworthy because of its rarity. The still was taken in a wavelength of extreme ultraviolet light.

A view of the stamens opening like tiny parcels unwrapping allowing the filaments to burst out. Cropped and an opening parcel lightly sharpened with the sharpening tool.
The obvious parts of the flower masses are stamens, with the pollen at the tip of the filament; the petals are inconspicuous (see picture). Flower heads vary in colour with species; most are red, but some are yellow, green, orange or white. Each flower head produces a profusion of triple-celled seed capsules around a stem which remain on the plant with the seeds enclosed until stimulated to open when the plant dies or fire causes the release of the seeds. (A few species release the seeds annually.)

Taken for the Flickr Friday theme of Power. The lightbulb, which is held vertically in a man's fingers, appears to glow despite not being attached to an electricity supply. The glowing filament is visible and the hand is illuminated by the light from this conventional lightbulb. Taken with a Fuji XT2 and 18-55mm lens in the studio. The image is a composite of four separate close up photographs. The image is low key.
I was taking Remy for a walk and of course scanning the leaves for caterpillars. I spotted a tiny bit of "debris" on a maple leaf. Of course I have to check out anything that looks out of place and sure enough it was a tiny instar of a "Nematocampa resistaria" Horned Spanworm! One of the Filament Bearers they are an amazing and beautiful caterpillar! Ellicott City, Howard County, MD
This is a scientific capture rather than an aesthetic one — acquired in H-alpha using a Lunt LS60MT with a Powermate 2.5x, from a narrow ROI (region of interest: using only a small part of your sensor (gives higher frame rate (good for lucky imagining))) and later heavily cropped. Despite the low resolution, it illustrates a key solar phenomenon: the continuity between a filament and a prominence. The structure spans across the solar disk as a dark, suspended filament and then extends beyond the limb where it becomes visible in emission as a prominence. Both are manifestations of the same magnetic structure — relatively cool plasma supported in the solar corona, seen in absorption or emission depending on the viewing angle.
A rough image, but it captures the physics — and that's it is about sometimes : Observing what you have been told, a deeper form of knowledge then you form (said Yoda).

Nothing is better to me than being up close with a lightning bolt so you actually see all the filaments you might miss from being further away. Taken on July 27th north of Sierra Vista along Highway 82.
Light?
Have you ever wondered from where light came
If the wondering of light is just a game
If light is playing a trick on our eyes
If light is just a bunch of lies
If light has a temperature cold as ice
If light is actually hot as rice
If light can run around the room
If light will lead us to our doom
If light can catch a traveling ball
If light can hear our pleading call
If light needs us to seeing the dark
If light can produce a menacing bark
If light can flow as fast as sound
If light is only on earth bound
If light can take a human form
If light can get caught up in a storm
I often wonder what light can do
but its secrets are not for me and you

A throwback to one of the most beatiful fish I kept - the filament barb. As seen here, adult males develop a more intense colour pattern than females and exhibit noticeable tubercules on the head when in spawning condition - when I first saw this I thought they had developed a sickness haha!
A bright solar prominence rose up from the Sun and twisted around in about a six-hour period (Apr. 21, 2015). While some of the material broke away into space, much of it fell back into the Sun. The images were taken in a wavelength of extreme ultraviolet light. At its greatest height, the plume extended out many times the size of Earth, allowing numerous amateur astronomers to observe this event with their solar telescopes.

La reserva comunitaria de Anja es una pequeña área protegida en Madagascar . Fue creado por una comunidad del pueblo que lo gestiona en su totalidad. Está orientado hacia la conservación de la naturaleza, el turismo y el desarrollo económico de la localidad.
La reserva alberga la población de lémures de cola anillada más densa de toda la isla.
La reserva está situada cerca de la carretera nacional N o 7, a medio camino entre el Parque Nacional Isalo al sur y Ranomafana norte, dos de los parques más visitados del país. Esta situación probablemente esté en el origen del gran número de visitantes que se detienen allí, y corolario del éxito del proyecto.
La reserva comunitaria de Anja cubre 34 hectáreas de bosque seco, rodeada de sabanas, arrozales y huertas. El paisaje está dominado por tres grandes formaciones de granito aisladas, el Telo Mirahavavy o "las Tres Hermanas".
Anja Miray es una asociación de derecho malgache , creada en 1999. Todos los habitantes de Anja, es decir, unas 2.500 personas, pueden unirse si lo desean. La gestión del bosque le fue cedida por el gobierno malgache en 2001, en virtud de la ley de transferencia de la gestión de los recursos naturales, de 1996. En 2009, pasó la superficie de tierra bajo el control de la asociación Anja Miray. De 60 ha (concedida en 2001) a 72 ha .
El premio “Ecuador”, que premia los esfuerzos de las comunidades para reducir la pobreza a través de la conservación y el uso sostenible de la biodiversidad, fue otorgado a la asociación Anja Miray en 2012.
Sin embargo, un estudio apunta a las desigualdades de género que persisten en la reserva, destacando, en particular, que solo el 15,4% de las mujeres son social, política y económicamente autónomas.
Las ganancias de la reserva comunitaria de Anja permitieron financiar la construcción de dos escuelas y un programa de apoyo agrícola con distribución de semillas e insumos.
En 2011, la reserva de Anja recibió a 12.000 visitantes, cada uno pagando una tarifa de entrada de 20.000 Ariaris (alrededor de 5 € ), además de la tarifa de grupo de 18 € . En 2019, el turismo generó alrededor de 27.000 € de facturación. Los ingresos fueron suficientes para contratar a 85 guías y otros agentes.

The Anja Community Reserve is a woodland area and freshwater lake, situated at the base a large cliff. Much of the reserve is dominated by fallen rocks and boulders and there are two small caves providing habitat for bats and owls. This reserve has much sheltered habitat in the pocket of forest that has established between the vast boulders.
The reserve was created in 2001 with the support on the UNDP to help preserve the local environment and wildlife, and to provide additional employment and income to the local community.
The reserve is home to the highest concentration of maki, or ring-tailed lemurs, in all of Madagascar. The people, who have a belief in not eating the maki, used to sell the maki to outsiders. However, after finding that 95% of makis in Madagascar are now gone, the people initiated the formation of a nature reserve, effectively establishing the world's largest congregation site for makis. Due to its high biological, cultural, and natural importance, scholars have suggested the possibility of its inclusion in the UNESCO World Heritage List.
The reserve is located 13 km south of Ambalavao, between the towns of Fianarantsoa and Ihosy, on National Road 7, and is a popular stop for holiday tours operators traveling between the Antananarivo and the south of Madagascar.
Visitors are welcome, but must be accompanied by a local guide. There are two main trails. The shorter trail can be completed in around one to two hours, but you should allow up to six hours for the longer trail which includes a hike to the top of the mountain. Fees apply.
The reserve is maintained by Association Anja Miray, a local group established in response to the degradation of the forest. The association's ecotourism initiative helps to fund community works projects related to education and health alongside conservation activities. The growth of ecotourism has also helped to diversify the local economy, encouraging fish farming and tree nurseries. Previously, forest lands were being cleared for corn planting and lemurs were hunted as a source of protein. The association received support from the United Nations Development Programme (including an Equator Prize in 2012) and the Global Environment Facility.
Anja Reserve is home to about 300 ring-tailed lemurs (Lemur catta) as well as three species of lizard:
Androngo or the Madagascar Girdled Lizard (Zonosaurus madagascariensis)
Katasataka or Barbour's day gecko (Phelsuma barbouri)
Dangalia lizard (Chalarodon madagascariensis)
The ring-tailed lemurs are used to visitors, so it is possible to approach to within a few meters for photos. However, feeding them, which was once permitted, is now prohibited.
Two bizarre species of planthopper are frequently observed at Anja, and the local guides will point out these strange-looking insects to visitors as they pass by. The Flatida rosea nymphs congregate in groups and are covered in white waxy filaments. The Malagasy Lantern Bug (Zanna madagascariensis) has a white waxy dusty coating and a large orange lantern-like snout.
