The foreground distracted from the constellation, and the sky was a bit too bright due to light pollution, so I cropped the image to focus on the stars, and played with the exposure and contrast settings to achieve a black sky against which the stars could stand out. 211 Group on Ontology Management, graph For iPhone, I highly recommend the NightCap Pro app and have seen good images taken with the Android app Camera FV-5. Radical innovation is the polar opposite of disruptive innovation. ssn:hasDeployment, sosa:Actuator, Same Day Tyre Fitting Tread Depth and Safety Mobile Tyre Fitting Choosing The Best Tyres What Are Run … The following examples illustrate how the terms related to Systems and their Deployment can be used: sosa:Platform, SensorML and O&M are complementary viewpoints. The graphic above portrays an example of the PolarFinder app screen, next to the view through the Sky-Watcher HEQ-5 polar scope. Samples are thus artifacts of an observational strategy, and usually have no significant function outside of their role in the observation process. Describing a plan for some actuation or observation in the future is not covered by this specification. Classes and relationships involved in Observation (SOSA), Classes and relationships involved in Observation (SOSA/SSN), An observable quality (property, characteristic) of a. Recipients of this document are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to provide supporting documentation. Annex C in Correction to some https namespace usage that crept into the FPWD. The suggested prefix for the SOSA namespace is sosa. (7.1 kg) Dec. top plate 1.5 lb. Suppose you want to aim to a target somewhat to the left of the North Star from the initial position. The StarPointer, once aligned to the telescope itself, makes it easy to do this. He and his images have also been televised in the United States (ABC World News Tonight with David Muir,) Europe (Dutch Public Broadcasting,) and Canada (CTV Canada AM.). In contrast, O&M was designed to be more 'user-centric' with the target of the observation and the (12.5 kg) Dec. axis: 15.6 lb. The Keypad is an ideal choice for these users. I’ve been using my iPhone for astrophotography since 2012, and have learned some techniques for taking night photos that show more than fuzzy, out-of-focus dots. should be supported by RDF and SPARQL engines to support the comparison of quantity values. citizen science, observation-driven ontology engineering, and the Web of Things. This section explains the rationale and method for modularizing SSN, i.e., offering several distinct ontologies that are similar in their domain of discourse, but with different IoT devices, data intensive applications (with the possibility of using lightweight reasoning), and so on. sampling:natureOfRelationship, The GTOCP4 Control Box offers multiple connection options to suit your requirements including Wi-Fi, Ethernet, USB and serial ports. ssn:Output, IRI: http://www.w3.org/ns/sosa/usedProcedure, IRI: http://www.w3.org/ns/ssn/implementedBy.

The first category comprises those approaches that focus on the composition of existing ontologies by means of integrating and mapping ontologies, most commonly through owl:import statements. As mentioned previously, our extensive testing procedures include several PEMPro runs so that your new mount will perform with optimum PE correction out of the box. Massive thrust bearings and preloaded shaft bearings provide excellent stability under all imaging situations. An RDF file containing a graph The large "captain's wheel" knob, convenient to grasp and turn, performs the fine adjustments. ex:OnOffStatus), or specific to a single feature of interest (e.g., , ). , ssn:detects In the following example, the ice core is a sample of the Antarctic ice sheet, and observations are made on the ice core. Alfa Romeo Audi BMW Jaguar Land Rover Mercedes Mini Ferarri Lamborghini Porsche Mclaren Volvo Tyres Tyre Type. The ontology is composed of multiple modules. Those parts of SSN that use DUL terms have been separated into the. An overview of the main classes and properties inside the ontology modules can be seen in the following figures, from the perspectives of Observation, Actuation and Sampling. (KEYVFK2), GTOCP4 Control Box for all GTO Mounts, except Mach2GTO. And, if you have a telescope, smartphones can capture an amazing amount of detail through the eyepiece. This is very useful for long exposure H-alpha or in cases where a large number of individual exposures are needed for stacking. When I used the 1100GTO mount, I had to say that I felt, like Oscar Wilde,“always satisfied with the very best.”, This 16" Dovetail Saddle Plate, designed and manufactured by Astro-Physics, is the ultimate in versa, This 10” dual-style saddle plate fills the need of customers who have multiple scopes. A pioneer in smartphone astrophotography, Andrew has been using his iPhone to capture close up views of the sun, moon, planets, and brightest deep sky objects through his telescopes since 2011. Note that SSN-SSNX imports SSN-DUL. Also, PDFs of 1100GTO and GTO Keypad instruction manuals. (1100GTO, 1100GTO-AE, 1100GTO-AEL). locations corresponds to a sosa:Sample of the entire room. The DUL ontology, that was imported in SSN, is no longer imported and all axioms using terms from DUL have been removed from SSN and collected in the DUL-SSN alignment module. SOSA axioms are shown in green, while SSN-only axioms are shown in blue. Drawing on considerable implementation and application experience with SSN and sensor and observation ontologies more broadly, the new SSN and SOSA ontologies presented here are set out to address changes in scope and audience, shortcomings of Classes generally aligned with prov:Entity in yellow ellipses; with prov:Activity in purple boxes; with prov:Agent in orange boxes. Thus, an alignment that document contains a large set of examples. SOSA axioms are shown in green, while SSN-only axioms are shown in blue. The non-rail sentence alignment variation is rarer because it appears to have been produced in lower numbers then the silver marker rail dial 16550. , denote the same individual. Absolute Encoders allow the mount to know its exact location regardless of accidental software errors and will allow its recovery. W3C maintains a public list of any patent Blindsight is the Hugo Award–nominated novel by Peter Watts, "a hard science fiction writer through and through and one of the very best alive" (The Globe and Mail). sosa:isObservedBy, It is similar to HSL in that way, although it is far more perceptually uniform. SSN A tripod is your best option and there are small, smartphone-specific tripods available on Amazon and eBay as well as adapters (like those made by Studio Neat) that can attach to existing tripods. Best wishes. Also, do you use The iPhone setting for regular movies or slow motion? The following examples illustrate how the terms related to Observation can be used: This section introduces the following classes and properties: sosa:ObservableProperty, To get around this, you’ll want to download an app that essentially tricks your phone into taking the equivalent of a long exposure. Also, do you use The iPhone setting for regular movies or slow motion? Found inside – Page 76... rotator housed in a plastic box of about 100 x 140 mm, into which a polar scope is ftted for alignment purposes. ... Here, the wedge is a modifed Manfrotto geared head. fg.17 SkySafari on an iPhone, one of several applications that. In order to optimize performance even further, we use a special version of Ray Gralak's PEMPro developed specifically for our test equipment. have identified a major issue in its complexity, partly due to the layering underneath the Dolce-UltraLite (DUL) upper level ontology. All in all, through the lens of smartphone dependency, the book makes the argument for digital mindfulness in a device age that threatens our privacy, sociability, attention, and cognitive abilities. A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers.Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. The class oboe:Entity appears in OBOE as the range of the oboe:ofEntity and oboe:hasValue properties, so we interpret it as a general superclass. ssn-system:DetectionLimit, ex:LightActuator), or specific to a single feature of interest (e.g., , ). ssn:inDeployment, IRI: http://www.w3.org/ns/sosa/isHostedBy, IRI: http://www.w3.org/ns/ssn/hasSubSystem, IRI: http://www.w3.org/ns/ssn/deployedSystem, IRI: http://www.w3.org/ns/ssn/hasDeployment, IRI: http://www.w3.org/ns/ssn/deployedOnPlatform, IRI: http://www.w3.org/ns/ssn/inDeployment, The namespace for system capabilities, operating ranges, and survival ranges terms is Alignment Module. sosa:hasSimpleResult , sosa:resultTime. An OWL implementation of O&M may be generated by explicit translation of the UML following rules specified in [ISO-19150-2] - see [OM-Heavy]. I use it on my iPhone 8 plus and it works perfectly. It truly lives up to the "polar" in its name: The outer cover is very cool to the touch, feeling so refreshing every time your head makes contact with it. ssn-system:hasSystemProperty, The heart of this mount is a precision gearbox using custom high-quality fine-pitch gears, coupled to a highly accurate worm and worm wheel. Spring-loaded worms maintain full contact under all guiding and slewing conditions, Automatic setting for worm mesh requires no adjustments over long time periods, Precision balance mechanism allows full backing off the worm from the worm wheel, Very low backlash gear train eliminates Dec reversal delays and provides high position accuracy during guiding, Polar Fork / Right Ascension Axis (R.A.)

Comments regarding this document are welcome. In fact, the control boxes for all of these mounts are interchangeable with one another in an emergency. Serial # of mount required for purchase. ssn-system:SurvivalRange, Modules that are horizontally layered may depend on each other, i.e., they may rely on the directional import of another horizontal module. I also used the vignette feature to darken the areas away from the constellation itself. The primary classes from [OBOE] are aligned with SOSA classes as follows. The weights slip easily onto the, We are thrilled to offer our Mach2GTO Universal Robotic mount that sets a new standard for portable, Why a 1600GTO? Joel, […] with a tripod and equatorial mount, is all you need to start astrophotography. This document was published by the Spatial Data on the Web Working Group as a Recommendation. Then, there is a section where I described three ethical principles and how they are embedded in the company, and then in the last section I proposed two possible changes in order to create a better strategy. Found inside – Page 27interaction between the neighbouring molecules due to polar side groups/elements such as (CN and Cl) serves to improve the molecular alignment considerably. This interaction stabilises orientation during fibre production and enhances ... Object properties ssn:isValueOf, ssn:produces and ssn:featureInObservation, along with a propertychain subproperty of produces and another propertychain subproperty of hasProperty, were introduced unintentionally in the FPWD. One can start the telescope under the mount while pointing at an object in the eastern part of the sky and track it all the way deep into the western sky. Claim(s) must disclose the information in accordance with The following figure provides an overview of the core classes and properties that are secifically related to modeling Procedures. The properties oboe:hasMeasurement and its inverse oboe:measurementFor link an oboe:Observation to its member oboe:Measurements. In Room 145 one of the walls is external in the building, so there is expected to be a temperature gradient across the room, and there are two sensors on different walls. , ssn:hasDeployment , sosa:hasFeatureOfInterest Don’t be disappointed if your first images don’t match those you see online. , ssn:wasOriginatedBy, Datatype Properties: These do not induce any changes in the intended meaning of the terms. (5.9 kg). The old SSN was perceived as too heavyweight (on its axiomatization) and too dependent on OWL reasoning by some users. While the namespaces for SSN and DUL have changed Network Notepad Enterprise 1.0.44 (x64) | 6.1 Mb Network Notepad is a software tool that was built in order to help you design network diagrams and save them for further analysis and safekeeping. In this book, The Boston Consulting Group’s Martin Reeves, Knut Haanæs, and Janmejaya Sinha offer a proven method to determine the strategy approach that is best for your company. Applications like missile, airplane, or very low earth orbit satellite tracking require faster tracking rates and more rapid changes to those tracking rates than our mounts allow. It is a stable document and may be used as reference material or cited from another document. ssn:Input, This means that the classes Each target listed in this guide contains our advice on imaging, photos of expected results, and a useful information table. We've also included a few cool facts about each target, a map to find it in the night sky, and more! The more complex aligments of SSN-XG classes are expressed as combinations of axiomatic statements as follows. The Semantic Sensor Network (SSN) ontology is an ontology for describing sensors and their observations, the involved procedures, the studied features of interest, the samples used to do so, and the observed properties, as well as actuators. Additional alignments from SOSA/SSN classes to O&M classes are as follows. However, ISO/TC 211 are currently developing a publication system to enable this and thus the use of these URIs as Linked Data.

Inclusion of the DUL alignment and the old SSN (of the SSN-XG) alignment. In this volume, you'll find a collection of low floor, high ceiling tasks that will help you do just that, by looking at the big ideas at the first-grade level through visualization, play, and investigation. It is also imported in the SSNX alignment module that aligns SSN to the previous version of SSN. sosa:isSampleOf, But, when I don’t have a tripod handy, I use any flat surface I can find such as a railing, pillar, or wall. The following Upper level ontologies are general knowledge ontologies that can be directionally imported in many domains, whereas our definition of higher level ontologies here refers Take a few minutes to link to descriptions of the varied software and devices that are available and see a full size version of this chart. The Keypad is a self-contained computer that allows you to control all essential telescope functions and includes an extensive database of objects. This section introduces the alignment of SSN to the DOLCE UltraLite upper ontology (DUL) which is the core dependency of the previous version of SSN. Each of these Passionate about communicating the wonder of the universe, Andrew shares his astrophotography images and tips and on a variety of social media channels, and encourages anyone with a smartphone to try their hand at night photography. A unique perspective on history and time, SkyView draws readers into a seven-hundred-year struggle between good and evil. This book provides a treatment of operations strategy which is clear and well structured, and seeks to apply some of the ideas of operations strategy to a variety of businesses and organisations. For those who use iPhones, a wireless camera release shutter is available on Amazon as the Gosky Camera Shutter Wire Control for Smartphones priced at $9.99. MIT, ERCIM, Keio, The system can be precisely controlled over a speed range of 4800:1, which allows 0.25x sidereal for manual guiding to 1200x sidereal for 5 degree per second slewing. This is particularly important in remote setups. Extremely solid, rugged, high payload mount, yet the equatorial head comes apart easily into two components for hassle-free field setup.

This alignment is so precise that their north-south positions are within an accuracy of up to 0.05 degrees. We are using cookies on PhotographingSpace.com, just like everyone else. Due to frequent user requests, this has been redesigned so that SSN (and SOSA) can be used entirely independently of DUL if desired. Once you go Mac, you never go back. And if you have this book, you’ll be more than happy to never go back. In The Ultimate Mac User Book, we’ve made a bold attempt to unveil an ideal Mac setup that works for anyone. These mapping approaches are not necessarily directional, but most approaches of ontology extraction rely on the directionality Additional alignments from O&M properties to SOSA are as follows. There are an essentially unlimited set of relationships between samples, so the nature of the relationship has its own class. Samples are typically subsets or extracts from the feature of interest of an observation. Correction to remove an asserted subclass of owl:Thing that was introduced into FPWD (these were both by-products of the DUL removal). For example, SOSA is intended to provide Schema.org-style semantic enrichment capabilities for data repositories managed by an audience broader than typical ontology sosa:madeObservation, This specification does not specify whether an instance of ssn:Property should be generic to all features of interest (e.g., ex:Temperature, First published in 1999, this is an expanded and updated edition of the best-selling, standard handbook on astrophotography for amateurs. Note that the ISS is generally within the mount’s tracking rate capabilities. before introducing any periodic error correction. I took this image from my backyard using an iPhone 6 and the NightCapApp in 2015. ssn:deployedOnPlatform, Reply. The other classes from the core SOSA ontology represent either real or information resources, so are interpreted as kinds of prov:Entity, thus: The following properties from SOSA have simple alignments with PROV properties: The final property alignment first requires some sub-properties of PROV properties to be defined: Then sosa:usedProcedure is given by a property chain axiom: An RDF file containing a graph corresponding to this alignment is available. The suggested prefix for the SSN namespace is ssn. With their different [SSN-PROV] and Cox [OM-Lite] have previously described alignments of the SSNX and Transition to the new namespace used by the DUL module. ssn-system:SystemProperty, However, if you purchase the 1100GTO without encoders, you may purchase the Absolute Encoder Kit (11AE-4-KIT or 11AE-4L-KIT) at some point in the future and install them yourself. Good luck! Sample, and Actuator (SOSA) ontology. In response to this, the new Semantic Sensor Network (SSN) ontology offers several ontology subsets that Although the 1600GTO mount is shown, these same features are available for the 1100GTO. However, in reverse, neither SOSA nor SSN import the Dolce-UltraLite The initial W3C Semantic Sensor Network Incubator Group ontology (SSN) was built around an ontology design pattern called the Stimulus The following namespace prefixes are used in the alignment to SOSA. In contrast, mounts that use commercial gearboxes have very small spur gears with tiny teeth and too few of them. Approximately 110 lb. For example, the data collected A quality of an entity. The wall also serves as a sosa:Platform on which the sensors are mounted. report. Introducing "EARS", the Earphone Audio Response System. However, these standards are not integrated and aligned In case of classes, e.g., specific features of interests such as rivers, these can be defined as subclasses of The SSN ontology is available at http://www.w3.org/ns/ssn/. Luckily, there are a number of apps that will allow you to improve your image right from your phone. sosa:hasFeatureOfInterest, The result of an sosa:Observation or an sosa:Actuation can be a quantity value with a numeric value and a unit of measure. The following example illustrate how the terms related to Actuations can be used: sosa:ActuatableProperty, In fact, LCH is the polar form of Lab. This section introduces the specifications for SOSA and SSN. The importing ontology assumes all the meaning of the imported terms used, by including all axioms relevant to the meaning of The following examples illustrate how the terms related to Samplings can be used: sosa:Sample, To make the most of your smartphone astrophotography, it’s worth investing some time to learn how to enhance the images after you’ve taken them.

The only stacking software I know of that directly accepts iPhone movies is Keith‘s Image stacker. SensorML provides extensive support for serialization of numeric data arrays and is particularly optimized for data that includes multiple parallel streams that must be processed together. The primary classes from SOSA are aligned with the PROV classes as follows. Depending on usage, re-measuring error and re-loading periodic error correction from one to four times a year is a good practice, especially if you do some unguided images from time to time. I look forward tl checking it out! as to explicitly address the need for light-weight semantics requested by the Linked Data community. these terms.
