Dedicated in 1980, the Very Large Array (VLA) has been an extraordinarily productive scientific instrument. Astronomers from around the world use it to study objects from our Solar System to the edges of the known Universe, billions of light-years from the Earth.
The telescope array consists of twenty-seven, 230-ton, 25-meter diameter dish antennas that together they comprise a single radio telescope system.
The VLA has made key observations of black holes and protoplanetary disks around young stars, discovered magnetic filaments and traced complex gas motions at the Milky Way's center, probed the Universe's cosmological parameters, and provided new knowledge about the physical mechanisms that produce radio emission.
The VLA is now being transformed into a new research instrument: the Expanded Very Large Array (EVLA). By 2012, new state-of-the-art electronics and software will have completely transformed the VLA into the EVLA, a much more capable research tool with more than ten times the VLA's sensitivity. Reinvigorated by new technologies, the EVLA will push the frontiers of science and knowledge for decades to come.
The Sun was fluffy today with lots of prominences protruding all around the limb. I still can't make a full-disk shot in Hα so I concentrated on huge cloud of gas floating aloft the solar magnetic field. Since it didn't escape, it would eventually fall down on the Sun sooner or later. Maybe it would be possible to see how the prominence turns into a filament.
It is rather hard to identify the same feature in white-light and in Hα - the Sun looks too different in those lights, especially at different magnifications. Only the spots are prominent in both "channels".
Aquisition time: 26.08.2013, 08:45 MSK (UTC+4)
Image orientation: straight for all panels (North is up, East is to the left).
Equipment:
Hα: Canon EOS 60D (unmodded) coupled to Coronado PST via SpaceWeatherLive.com-style modified eye-piece projection adapter with modified 20 mm eyepiece on photo-tripod.
Aperture 40 mm
Native focal length 400 mm
Effective focal length 1995 mm
Tv = 1/13 seconds
Av (effective) = f/50
ISO 400
Exposures: 10 of 25 (image quality was set to sRAW, resulting in 2592x1728 frames with diameter of solar disk around 2050 pix)
Processing: images were converted to monochrome and pre-cropped to 717x717 pix in Canon DPP and exported as 16-bit TIFFs. Images were stacked in Registax 6 and subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Cauchy-type PSF, size 7 units, 5 iterations). Contrast enchancement and coloration (in "artisitc" way :) was made in Photoshop.
The right panel is the most succesfull single frame, deconvolved in the same way and routinely colorised. The final image was scaled down and the zone of mis-tuning was cropped away.
White-light: Canon EF 70-200 f/2.8L IS + USM lens + EF 2x III extender @200 mm with double polarization filter on EOS 60D mounted on photo tripod via Manfrotto 410 Junior geared head (codenamed "The Glimpser").
Filter: Cokin linear polarization filter @90° to Doerr circular.
Aperture 71 (40) mm
Focal length 400 mm
Av = f/10
Tv = 1/1600 sec
ISO 100
Exposures: 15 of 25
Processing: in Canon DPP the contrast of original RAW was set to "linear" and images were converted into monochrome. RAWs were converted into 16 bit TIFFs and were fed to Registax 6. Result were deconvolved (Cauchy type PSF, 1,1 units, 5 iterations) in Astra Image Pro 3. Final touches were made with Curves and assembled in Photoshop.
Today's Sun, crackling with filaments and really coming to life, contrasting with the moon from a few weeks ago. All taken with the Philips webcam and stitched together in PS CS3.
Another view of the solar filament captured yesterday. This time in false colour. TAL100RS, Quark Chromosphere, CGEMDX mount. ZWO174mm.
Elytra - Filament Pavilion.
An art installation which is being built by a robot. Created by the University of Stuttgart, it's here until the 5th of November 2016.

Because of the way the Sony NEX-5 is designed, pixel-level Live View works only when the camera is on a tripod. For hand-held photography, you are better off taking your chances looking at the full image on the LCD back. That is the way I have been shooting almost all of the NEX-5 images I have been posting.
Here, I tried to focus on the light bulbs inside the lamp. I would have been pleased to just see the bulbs in good focus. I was surprised that I even got the filaments in good focus.

Elytra Filament Pavilion is a newly-commissioned pavilion for the V&A Engineering Season. It explores the impact of emerging robotic technologies on architectural design, engineering and making. It is inspired by a lightweight construction principle found in nature, the filament structures of the shells of flying beetles known as elytra. The Pavilion is an undulating canopy of glass and carbon fibre cells produced using an innovative robotic winding technique.

"Passion" does not refer to love, but to the Passion of Christ on the cross. In the 15th and 16th centuries, Spanish Christian missionaries discovered this flower and adopted its unique physical structures as symbols of Crucifixion. For example: the radial filaments which can number more than a hundred and vary from flower to flower represent the Crown of Thorns. The ten petals and sepals represent the ten faithful apostles. The top 3 stigmata represent the 3 nails and the lower 5 anthers represent the 5 wounds. The flower has been given names related to this symbolism throughout Europe since that time. In Spain, it is known as Espina de Cristo (Christ's Thorn). In Germany it was once known as Muttergottes-Schuzchen (Mother-of-God's Star).
In Israel they are referred to as clock-flower (×©×¢×•× ×™×ª). In Japan, they are known as clock-faced flowers.
In North America they are also called the Maypop, the water lemon, and the wild apricot (after its fruit). Native Americans in the Tennessee area called it ocoee, and the Ocoee River and valley are named after it.
