astrophotography

<p>Acabo de actualizar mi dataset sobre contaminación lumínica nocturna global generado con mi herramienta radiance-geojson (<a href="https://codeberg.org/imigueldiaz/radiance-geojson" rel="nofollow" class="ellipsis" title="codeberg.org/imigueldiaz/radiance-geojson"><span class="invisible">https://</span><span class="ellipsis">codeberg.org/imigueldiaz/radia</span><span class="invisible">nce-geojson</span></a>). Contiene archivos JSON (.json.gz) y un dump completo en PostGIS (restaurada ocupa 27GB, con casi 140 millones de puntos georreferenciados), con datos de radiancia, brillo del cielo y clasificación Bortle para 173 países a 0.5 km de resolución.

<p>Subí a PeerTube mi clase de técnicas instrumentales, telescopios y astrofotografía que di para el curso de Educación Permanente en CURE Rocha - UdelaR. Los curso de educación permanente son no especializados y son aptos para todo público por lo que son de carácter general e introductorios y su finalidad es transmitir conocimiento a la comunidad, generar lazos sociedad civil y crear lazos interdisciplinarios con otros actores, en este caso, con gente vinculada al turismo astronómico, conservación de ecosistemas y gestión ambiental.

<p>TOPIC&gt;</p><p>A Path North<br> * Image Credit &amp; Copyright: Mario Konang</p><p>Explanation: <br>What happens if you keep going north? The direction north on the Earth, the place on your horizon below the northern spin pole of the Earth -- around which other stars appear to slowly swirl, will remain the same. This spin-pole-of-the-north will never move from its fixed location on the sky -- night or day -- and its height will always match your latitude. The further north you go, the higher the north spin pole will appear. Eventually, if you can reach the Earth&#x27;s North Pole, the stars will circle a point directly over your head. Pictured, a four-hour long stack of images shows stars trailing in circles around this north celestial pole. The bright star near the north celestial pole is Polaris, known as the North Star. The bright path was created by the astrophotographer&#x27;s headlamp as he zigzagged up a hill just over a week ago in Lower Saxony, Germany. The astrophotographer can be seen, at times, in shadow. Actually, the Earth has two spin poles -- and much the same would happen if you started below the Earth&#x27;s equator and went south. </p><p><a href="https://apod.nasa.gov/apod/ap200407.html" rel="nofollow" class="ellipsis" title="apod.nasa.gov/apod/ap200407.html"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap200407.ht</span><span class="invisible">ml</span></a></p><p><a href="/tags/space/" rel="tag">#space</a> <a href="/tags/earth/" rel="tag">#earth</a> <a href="/tags/astrophotography/" rel="tag">#astrophotography</a> <a href="/tags/photography/" rel="tag">#photography</a> <a href="/tags/astroart/" rel="tag">#astroart</a> <a href="/tags/art/" rel="tag">#art</a> <a href="/tags/science/" rel="tag">#science</a> <a href="/tags/nature/" rel="tag">#nature</a> <a href="/tags/education/" rel="tag">#education</a></p>

<p>Spectacular <a href="/tags/sunspots/" rel="tag">#Sunspots</a> visible in this stacked picture of the Sun, taken from North Oxfordshire in the UK today. There are two very (very!) large sunspots visible in the lower third of the disk. Leftmost is 4296 and next to it is 4294. The ‘small one’ to the right is 4298 and that’s about the size of Earth. 4294 and 96 are getting some attention as they are very big and chucking out X flares. <br><a href="/tags/astrophotography/" rel="tag">#Astrophotography</a></p>

<p>2018, Lyrid meteor shower, created from an overnight run of automated <a href="/tags/astrophotography/" rel="tag">#astrophotography</a> with my DSLR.</p><p>I have never done <a href="/tags/meteorscatter/" rel="tag">#meteorscatter</a>. Pretty much the only way I&#x27;d get to do this mode is with an automated system. Which, sounds super fun to build. A sensor to detect paths, and then a radio to order to give it a shot.</p>
