Lik Observatory:
Lick Observatory was the world's first permanently occupied mountain-top observatory.
The observatory, in a Classical Revival style structure, was constructed between 1876 and 1887, from a bequest from James Lick. In 1887 Lick's body was buried under the future site of the telescope, with a brass tablet bearing the inscription, "Here lies the body of James Lick".
Before construction could begin, a road to the site had to be built. All of the construction materials had to be brought to the site by horse and mule-drawn wagons, which could not negotiate a steep grade. To keep the grade below 6.5%, the road had to take a very winding and sinuous path, which the modern-day road (SR 130) still follows. Tradition maintains that this road has exactly 365 turns.

Space Police Planetary Hammerhead Incident Support Harrier
aka- The Big P.H.I.S.H.
Made for #febrovery this is an ode to my childhood in two ways: One of my favorite sets growing up was the Solar Snooper from the "green" era of Space Police. The other influence was my brother and my favorite non-LEGO toys- the Cobra Hammerhead from G.I.Joe.
This rover reuses the wheels I made for my MTron Gigaton Flux Inductor moc. The P.H.I.S.H. operates on planets with water and is amphibious by nature. When the Aquanauts call for help to deal with pesky Aquasharks the Space Police are there to help with this enforcement vehicle. The vehicle carries two Poseidon Darts, each equipped with 4 torpedoes and a harpoon cannon plus a holding compartment for criminals behind the pilot. There are also two T.U.N.A subs (Tactical Underwater Nautical Attack sub) each carrying two torpedoes.
On the harrier itself are two torpedoes, a rotating dual harpoon cannon, and two dual barrel forward-facing cannons. The vehicle is operated by two drivers, two Poseidon Dart pilots, two T.U.N.A. sub pilots, and an additional enforcement officer.
Hope you like this nostalgic build. It was created using the Greyscalegorilla Plus Plugins, Bricklink Studio, Cinema4D, and Photoshop on a Puget Systems machine. I started this build two days ago and took roughly 8 hrs to make.
I made a shot similar to this back around Christmas 2016. I wanted to try out a new lens - I sort of like this one much better than the previous! The warped bokeh really leads the eyes towards the light.🚀🌌
A planetary nebula found in the constellation of Camelopardalis (The Giraffe). Also known as the Oyster Nebula.
A little under 5,000 light years distant from Earth, it's another one of William Herschel's discoveries in 1787.

Skywatcher quattro 8" S & f4 aplanatic coma corrector
HEQ5 pro mount guided with an Altair 50mm & GPcam setup
Canon 450D astro modded with Astronomik CLS CCD EOS APS-C clip filter. Neewer Intervalometer used to control the exposures.
The Dumbbell Nebula, M27, is a planetary nebula that lies some 1400 light years away in the constellation Vulpecula. It was the first planetary nebula discovered. Planetary nebulae consist of expanding ionized gas ejected from red giant stars. What's left is a very hot star, a white dwarf, and the UV radiation from the star ionizes the gas, providing the light we see.

A downward view of ESA’s rock-strewn recreation of the Red Planet, designed to put prototype planetary rovers through their paces.
Officially part of the Planetary Robotics Laboratory at the Agency’s ESTEC technical centre in Noordwijk, the Netherlands, the nickname of this test site is the ‘Mars Yard’.
An 9 x 9 m square filled with sand and different types of gravel and rocks, it is used to assess rover locomotion and navigation as well as the traction of wheels and other mechanisms – then check how these elements work together in practice, with tests observed using precision cameras and sensors.
The Planetary Robotics Lab is part of a suite of more than 35 ESA laboratories focused on all aspects of space engineering, available to wider European Member States companies as well as ESA projects.

I’m interested in the silent shutter for lunar and planetary images because eliminating mechanical shutter wear could free me to improve the quality of my images by taking many more frames and getting better lucky images for stacking when atmospheric seeing isn't at it’s best. Because the extra noise introduced by the electronic rolling shutter used for silent shutter images is far below the eight bit resolution offered by compressed images, I decided to compare the quality of processed images taken with the two techniques as well as the original images.
These images are from my first night out with the a6300 which was at prime focus on a Questar f15 1400/89mm telescope. Images were take at ISO 200 for 1/50 sec. I took about 40 images each with the mechanical shutter (with the electronic first curtain shutter option to minimize vibration) and with the fully electronic silent shutter. The quality of the images was auto graded and the best 8 were selected from each batch. Because of the wide, half degree, field of view atmospheric seeing can cause mirage like distortions of the Moon’s surface. This isn’t a problem for small area shots of the Moon or planetary images because of the smaller field of view. For full disk Moon images, the results of stacking are improved if each image is geometrically normalized before stacking. I use Nebulosity’s 8 parameter affine transformation. The cost of this is that each frame takes about one hour to align. This translates to a practical limit of 8 images for an overnight alignment run. Processing consisted of deconvolution and wavelet processing in Lynkeos to recover resolution lost to the atmosphere and diffraction in the small, 89mm objective, telescope. The exposure curves are then adjusted to enhance contrast and slightly boost saturation in Photoshop.
One way to see the quality of the low intensity data near the noise floor is to examine the terminator region. You can see detail extend into the dark part of the moon in the processed images. The post processing of the two images was similar, but not identical. As you can see in the raw images there were slight differences in exposure although the camera settings were the same except for the silent shutter setting. These may be because of the silent shutter or differences in transparency of the sky between the two sets of exposures.
My current thoughts on astrophotography with the a6300 so far are as follows.
Measurements that I’ve seen of the images of the electronic silent rolling shutter on the Sony a7 series cameras show about a stop of increase in noise at low ISO speed compared to the mechanical shutter.
For dim targets like DSOs where noise must be minimized and relatively few, long exposure, images are stacked - the mechanical shutter is clearly a win.
For small bright targets like planets where resolution must be maximized and cropped video is frequently used, the extra noise in video capture (or wide FOV silent shutter shots) isn’t an issue. Stacking more images can reduce noise and the video codecs don’t capture the full raw dynamic range in any case. Video (or silent shutter for the widest FOV) works well to capture the thousands of frames that are preferred, without mechanical wear on the shutter mechanism.
Full disk images of the moon are an in between case. The images are bright and the number that I stack is limited by the long processing time for the affine geometric normalization. I’d like to have more full disk images to choose from, without wearing out my mechanical shutter. From my results so far it seems that to see a difference that silent shutter makes in quality of the final result takes pixel peeping and may be mostly due to seeing and transparency variation.

I know, this kinda falls short of the usual stuff I post and it may be of interest to nobody but I love the chaos in these images and how my imagination is triggered by it. For me this looks like a catastrophic event around the orbit of a planet, the barely lit center of the circle. The circles themselves could be planetary rings with the brighter one being ignited by the doomsday event.
On the other hand, this photo's imagined story stands in stark contrast of it's real scale. This being only a small cut-off wheel of 22mm in diameter, running at 20.000 rpm, making contact with a steel part.

The brilliant starry sky, the red sand and the ice structures piercing the foreground of this image combine to give the impression of a desert far from the reach of human footprints. A landscape that could easily be mistaken for the polar regions of our distant neighbour Mars.
The jagged tooth-like formations are not on the Red Planet however, but on the sloping hills of the Atacama Desert.
The formations are called penitentes — structures made of snow and ice that form mostly at high altitudes. The low pressure, moisture and temperature at these altitudes help to create this interesting and rare behaviour in the freezing of ice. The strange structures also have a tendency to orient themselves towards the Sun, which is why they are all perfectly aligned like a carefully tended garden of ice.
As if this beautiful quirk of nature wasn’t enough, above the structures lies an even more magnificent sight.
The large blue star just above the hill is Sirius — the brightest star in the sky. Following the horizon to the left from Sirius, the ancient red supergiant Betelgeuse can be seen, located in the constellation of Orion. The second brightest object after Sirius is Canopus and it is seen here as a brilliant blue point at the right hand side of the frame.
This strange and alien-looking image was taken by ESO Photo Ambassador Babak A. Tafreshi.

A large-scale defense cannon for the Star Vikings collaboration at BrickCon 2014.
There is internal gearing to lock the cannon's elevation-of-fire, controlled by rotating the rear lower-left cone heat sink unit. The landscape technique was inspired by Blake Foster's M:Tron Magnet Factory.
I also made a Star Vikings dropship. See the total collaboration in the Star Vikings group.

BluShock Planetary Exploration is the new, official name given to BluShock Coalition's world designing and RP exploration operation, responsible for creating new, exotic and detailed worlds, for the BluShock franchise RP group.
Complex and incredibly detailed worlds at your fingertips.
Exclusive to BluShock.
Several new planet projects are currently in development, and we can't wait to share more in the coming months.
What started as a fun project with Vanargand, and Planet Idun, exploded into an ambitious project that gave us all this incredible idea. SL doesn't have enough exotic worlds and planets to explore, so we're changing this from here onwards.
Our next main world is Ingemar. An underwater planet, with crashed ships and wreckages above sea level, and deep underwater caves, with ancient aliens, as tall as skyscrapers, who once ruled the races of the galaxy.
It's FebRovery again, my favourite themed building month.
So let's begin with a modification of set 10497 (or as I like to call it, the "UCS Galaxy Explorer") into a rover.
As far as names go, "Planetary Explorer" was the obvious and only choice. The rear cargo compartment contains a small skimmer-type vehicle to mirror the rover carried by the original
The red (Ha Signal) is sh2-129, the flying bat nebula. The blue squid nebula (OIII signal) in this image (OU4) was discovered by the French Amateur Astrophotographer Nicolas Outters in 2011. It is very faint. I used a tone mapping process originally described by J-P Metsavainio to bring it out.
Other-worldly looking camp near Diamond Mesa below Forester Pass. A high altitude night leading up to the last big day of my hike that would put me on top of Mt. Whitney at the end of this same day for an even higher night in this different world above 12,000 feet. It was 12:33am when this image was created.
The reddish "star" left of the moon is Mars, not an optical flaw in the lens. Mars won't be that big again for another 15 years, This was just 1 month after minimum distance (57.6 million kilometers)
I don't think I could have picked a colder night to head out for some light painting, but enjoyed it despite the blizzard conditions and fingers that felt like they were going to fall off!
Playing around with the strobe projector for the alien shadow. It's taking a bit of effort to create usable gobos, and not found a reliable way to use full colour yet, but working on it...
Image created in a single exposure, no Photoshop.
A small planetary scouting party surveys the deserted plain in hopes it will make a safe site to construct their home base.
The Vanguard is the bulk fighter of the Confederacy Navy. It's a light vessel designed to operate from both space carriers and ground bases. It can last a week on standby and a day in battles, such as short skirmishes and riot controls. When the power core is depleted it can be switched out easily at the base or with a resupply craft.
Dual tungsten rail guns can deal massive damage over long distances and the powerful shield protects the pilot from incoming hostiles. The angled position of the shield generators gives maximum protection to the cockpit from frontal attacks.
This is my entry in the Star Fighter category of Space Jam 2018!
Play features:
* Open the cockpit to access the pilot seat
* Replace the depleted power core
* Retractable landing gear
* Fire the rail guns with the aft mounted trigger
Here is a video of the play features: www.youtube.com/watch?v=4vI56lsmdjI

This was taken just before 6am on the morning of 15th May from a beach in the National Park, where there is less incidental light. They are quite visible in Sydney, but the whole sky was lit up with skys and constellations. Great spot to take night photographs of the sky, if you arrive early enough that is !!! it was already getting light. Sunrise was at 6.15am
Heres the write up I already posted on my other photograph taken a few days earlier.. I hope to have a few more pictures of this, during the month. I have added to it
Star gazers have another grand celestial event to celebrate. The finest planetary conjunction of the year will happen on May 11 when Venus passes very close to the south of Jupiter. The two brightest planets on the sky will not get this close anytime before August 2014.
Beginning May 11, the four planets Mercury, Venus, Jupiter and Mars will rearrange themselves to form different patterns in the sky. This celestial spectacle can be easily seen through the naked eye. On May 13, Mercury, Venus and Jupiter will form a triangle and on May 20, it will be Mars, Venus, and Mercury in the triangular position.
Though two other planets, Uranus and Neptune, will also participate in this show in the sky, but viewing them will need the aid of a telescope.
It is a rare phenomenon when so many planets can be viewed at one time on one section of the sky.
The rare planetary conjunction will end on May 30, when a crescent Moon also joins the party.
The truly remarkable event - when Jupiter lines up with Venus, Mercury and Mars in the pre-dawn sky - will be visible in Australia's eastern sky this Friday. Its the closest Planetary grouping until 2040
The alignment of the four planets, which happens only once every 50 to 100 years, will occur just before sunrise, the Sydney Observatory says.
"Every couple of years you get two or three planets that come close together, but to have four is particularly rare," the observatory's education officer, Geoffrey Wyatt, said.
The last time Australians saw such a show was in 1910, and the next occasion would not be until 2056, Mr Wyatt said.
During the alignment, from 5am (AEST) on Friday, the four planets will be visible just above the horizon in the east.
Venus, in the middle of the group, will be the brightest. Just above and to the left will be Jupiter, while Mercury will be to the right of Jupiter and slightly fainter.
Early risers have already noticed Jupiter and Venus in the eastern sky before sunrise, Mr Wyatt said.
"It looks pretty much like two headlights coming towards you. We are getting lots of calls already saying there are two bright lights in the sky."
He wouldn't speculate on how the alignment might influence people, astrologically speaking.
