The Protrek PRW3000. I wanted to have a similar watch for a long time, but always they just missed the functions I wanted.
The Protrek has them all, so I pre-ordered one. I really think it is a great watch. It is slim, not too big, a nice soft color, light.
I'll definitely will also buy the PRX3000.
Sorry for the dust as I just made some quick photo's!!

The titanium version of the PRW3000. First I bought the 'normal' version and now the titanium. I really like this watch. It has a lot of functions and wears very comfortabel.
If I would ever end up on a deserted island this is the watch I would like to wear.

One of my fave radios...it has just the right amount of kitsch appeal. Too bad TV went digital in the USA, I now only receive one TV station on this rig. It also covers AM/FM broadcast, aircraft, VHF public service, and, yes, shortwave!
This infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye.
The nebula, located about 700 light-years away in the constellation Aquarius, belongs to a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic butterflies were named for their resemblance to gas-giant planets.
Planetary nebulae are actually the remains of stars that once looked a lot like our sun.
When sun-like stars die, they puff out their outer gaseous layers. These layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible-light colors. Our own sun will blossom into a planetary nebula when it dies in about five billion years.
In Spitzer's infrared view of the Helix nebula, the eye looks more like that of a green monster's. Infrared light from the outer gaseous layers is represented in blues and greens. The white dwarf is visible as a tiny white dot in the center of the picture. The red color in the middle of the eye denotes the final layers of gas blown out when the star died.
The brighter red circle in the very center is the glow of a dusty disk circling the white dwarf (the disk itself is too small to be resolved). This dust, discovered by Spitzer's infrared heat-seeking vision, was most likely kicked up by comets that survived the death of their star. Before the star died, its comets and possibly planets would have orbited the star in an orderly fashion. But when the star blew off its outer layers, the icy bodies and outer planets would have been tossed about and into each other, resulting in an ongoing cosmic dust storm. Any inner planets in the system would have burned up or been swallowed as their dying star expanded.
The Helix nebula is one of only a few dead-star systems in which evidence for comet survivors has been found.

NASA’s Spitzer Space Telescope has uncovered a hatchery for massive stars.
A new striking image from the infrared telescope shows a vibrant cloud called the Trifid Nebula dotted with glowing stellar “incubators.” Tucked deep inside these incubators are rapidly growing embryonic stars, whose warmth Spitzer was able to see for the first time with its powerful heat-seeking eyes.
The new view offers a rare glimpse at the earliest stages of massive star formation ? a time when developing stars are about to burst into existence.
“Massive stars develop in very dark regions so quickly that is hard to catch them forming,” said Dr. Jeonghee Rho of the Spitzer Science Center, California Institute of Technology, Pasadena, Calif., principal investigator of the recent observations. “With Spitzer, it’s like having an ultrasound for stars. We can see into dust cocoons and visualize how many embryos are in each of them.”
The new false-color image can be found at www.spitzer.caltech.edu/Media. It was presented today at the 205th meeting of the American Astronomical Society in San Diego, Calif.
The Trifid Nebula is a giant star-forming cloud of gas and dust located 5,400 light-years away in the constellation Sagittarius. Previous images taken by the Institute for Radioastronomy millimeter telescope in Spain show that the nebula contains four cold knots, or cores, of dust. Such cores are “incubators” where stars are born. Astronomers thought the ones in the Trifid Nebula were not yet ripe for stars. But, when Spitzer set its infrared eyes on all four cores, it found that they had already begun to develop warm stellar embryos.
“Spitzer can see the material from the dark cores falling onto the surfaces of the embryonic stars, because the material gets hotter as gravity draws it in,” said Dr. William T. Reach of the Spitzer Science Center, co-author of this new research. “By measuring the infrared brightness, we can not only see the individual embryos but determine their growth rate.”
The Trifid Nebula is unique in that it is dominated by one massive central star, 300,000 years old. Radiation and winds emanating from the star have sculpted the Trifid cloud into its current cavernous shape. These winds have also acted like shock waves to compress gas and dust into dark cores, whose gravity caused more material to fall inward until embryonic stars were formed. In time, the growing embryos will accumulate enough mass to ignite and explode out of their cores like baby birds busting out of their eggs.
Because the Trifid Nebula is home to just one massive star, it provides astronomers a rare chance to study an isolated family unit. All of the newfound stellar embryos are descended from the nebula’s main star. Said Rho, “Looking at the image, you know exactly where the embryos came from. We use their colors to determine how old they are. It’s like studying the family tree for a generation of stars.”
Spitzer discovered 30 embryonic stars in the Trifid Nebula’s four cores and dark clouds. Multiple embryos were found inside two massive cores, while a sole embryo was seen in each of the other two. This is one of the first times that clusters of embryos have been observed in single cores at this early stage of stellar development.
“In the cores with multiple embryos, we are seeing that the most massive and brightest of the bunch is near the center. This implies that the developing stars are competing for materials, and that the embryo with the most material will grow to be the largest star,” said Dr. Bertrand Lefloch of Observatoire de Grenoble, France, co-author of the new research.
Spitzer also uncovered about 120 small baby stars buried inside the outer clouds of the nebula. These newborns were probably formed around the same time as the main massive star and are its smaller siblings.
Other authors of this work include Dr. Giovanni Fazio, Smithsonian Astrophysical Observatory, Cambridge, Mass.
NASA’s Jet Propulsion Laboratory, Pasadena, Calif., manages the Spitzer Space Telescope mission for NASA’s Science Mission Directorate, Washington, D.C. Science operations are conducted at the Spitzer Science Center, Pasadena, Calif. JPL is a division of Caltech.
The new Spitzer image is a combination of data from the telescope’s infrared array camera and multiband imaging photometer. The infrared array camera was built by NASA Goddard Space Flight Center, Greenbelt, Md.; its development was led by Fazio. The multiband imaging photometer was built by Ball Aerospace Corporation, Boulder, Colo., the University of Arizona, Tucson, and Boeing North American, Canoga Park, Calif. The instrument’s development was led by Dr.George Rieke, University of Arizona.

Edited Spitzer Space Telescope image of the supernova remnant G54.1+0.3.
Image source: www.spitzer.caltech.edu/news/2121-ssc2018-16-Exploding-St...
Original caption: This image of supernova remnant G54.1+0.3 includes radio, infrared and X-ray light.
The saturated yellow point at the center of the image indicates strong X-ray source at the center of the supernova remnant. This is an incredibly dense object called a neutron star, which can form as a star runs out of fuel to keep it inflated, and the unsupported material collapses down on to the star's core. G54.1+0.3 contains a special type of neutron star called a pulsar, which emits particularly bright radio and X-ray emissions.
The blue and green emissions show the presence of dust, including silica.
The red hues correspond to radio data from the Karl G. Jansky Very Large Array; green corresponds to 70 m wavelength infrared light from the European Space Agency's Herschel Space Observatory; blue corresponds to 24 m wavelength infrared light from the Multiband Imaging Photometer (MIPS) instrument on NASA's Spitzer Space Telescope; yellow corresponds to X-ray data from the Chandra X-ray Observatory.

After a beautiful sunset last night on Lake Lizzie, the sunrise from our office building in Fargo this morning was a winner, too. I don't know what it is about this time of the year in this region, but it seems like every sunset and sunrise is something special. I was recently looking at sunset/sunrise photos I've taken from past years from around here, and for some reason they seem to peak aesthetically in October and November. Not sure why?
This isn't just for show. The QT-50W completely tunes all four bands with exceptional smoothness and very good selectivity. No overloading on AM locals located just a few blocks away.
Chaetodon multicinctus. This appears to be a hybrid color pattern as the normal look has no dark patch in the back.
Landsat maps are of too low resolution to be of much help to hikers. Plus some areas were under clouds and patched by whomever with whatever. Trumped by Google Earth. Somebody with time to spare needs to do a full rez Landsat. Lots of potential in using multiband spectral stuff to identify uluhe, etc.

Complete back view of set. Two aerial sockets might seem strange to some, but is quite normal for 405 line sets post 1953. The initial BBC allocations were all Band 1, but when ITV joined the scene, Band 3 was opened up. Multiband aerials were not popular in the UK, possibly because they were seen as a compromise, except for good signal areas, and also that transmitters were not always co-sited.

Edited Spitzer Space Telescope image of Rho Ophiuchi and its nebula.
Original caption: Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from NASA's Spitzer Space Telescope. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions to our own solar system. Located near the constellations Scorpius and Ophiuchus, the nebula is about 407 light years away from Earth.
Rho Oph is a complex made up of a large main cloud of molecular hydrogen, a key molecule allowing new stars to form from cold cosmic gas, with two long streamers trailing off in different directions. Recent studies using the latest X-ray and infrared observations reveal more than 300 young stellar objects within the large central cloud. Their median age is only 300,000 years, very young compared to some of the universe's oldest stars, which are more than 12 billion years old.
This false-color image of Rho Oph's main cloud, Lynds 1688, was created with data from Spitzer's infrared array camera, which has the highest spatial resolution of Spitzer's three imaging instruments, and its multiband imaging photometer, best for detecting cooler
materials. Blue represents 3.6-micron light; green shows light of 8 microns; and red is 24-micron light. The multiple wavelengths reveal different aspects of the dust surrounding and between the embedded stars, yielding information about the stars and their birthplace.
The colors in this image reflect the relative temperatures and evolutionary states of the various stars. The youngest stars are surrounded by dusty disks of gas from which they, and their potential planetary systems, are forming. These young disk systems show up as red in this image. Some of these young stellar objects are surrounded by their own compact nebulae. More evolved stars, which have shed their natal material, are blue.
This infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye.
