𝙎𝙩𝙤𝙧𝙮 𝙤𝙛 𝙖𝙣 𝙀𝙡𝙚𝙘𝙩𝙧𝙤𝙣𝙞𝙘 𝙀𝙮𝙚 𝙎𝙪𝙧𝙜𝙚𝙧𝙮! As some of you may know, I am a Post-Silicon Evaluation Engineer during daytime and an Amateur Astronomer during the night. Telescope making, Astrophotography, etc. are my hobbies. #Astrophotography is an extremely demanding hobby with a steep #learning curve and very expensive to pursue. Equipment like dedicated astronomy cameras is costly and should be handled very carefully. This was in the year 2020 and I was just ramping up my astrophotography arsenal and I wanted a sensitive camera, badly. But my pocket wasn't as big as my dreams! Dedicated astro cameras are more sensitive to a broader spectrum of light (including, Infrared and Ultraviolet), where as normal SLR camera sensors have a filter Infront of it to cut off the extremes of the spectra. So, in principle, a DLSR camera may be used as an astronomy camera, if the filter in front of it can be removed. But, as you know, these are highly sensitive and delicate instruments and can be easily damaged if not handled carefully. How can a novice like me even think of doing it. But the #adventurer in me won't let it pass. And I did exactly that - 𝘢𝘯 𝘌𝘭𝘦𝘤𝘵𝘳𝘰𝘯𝘪𝘤 𝘌𝘺𝘦 𝘚𝘶𝘳𝘨𝘦𝘳𝘺! With help and support from Udayan Pandharipande I skimmed through the entire instruction from veteran Tony Hallas and jumped right in. There were almost 20 different types of screws to be taken out. Circuits were ESD sensitive. Each step in the forward process had to be documented and the exact steps need to be reversed to get back the camera in a working condition (pic: Row1, Column1). Even if you 1 step or a screw - you are SCREWED! It was important to stay hydrated and take enough breaks as it was very crucial to have full focus and attention. And finally, we could re-assemble the camera and sensor (pic: Row1, Column23) after taking out the filter (pic: Row1, Column2) that cut off the IR and Hydrogen-Alpha wavelengths, after 9 long hours. It was the time for the first test shot to actually see if the H-Alpha sensitivity has increased or not. I had already taken a test shot of the famous Rosette Nebula before the modification. Now I need to repeat the same after the modification is done. And viola! the sensitivity has increased! We were overjoyed. One can clearly see the increased sensitivity of the camera after modification from the attached screenshot. (pic: Row2, Column1,2) ############################################## PS: I still use this astro-modded camera to this day, and it is working like charm!

You're about to discover how MR and AR are completely revolutionising archaeology—and it's mind-blowing. Archaeologists at the University of Hong Kong are using these immersive technologies to interact with 3D models during excavations, reducing unnecessary digging and artefact removal. This is huge because archaeology has long been seen as a "destructive science." But now, researchers can virtually see removed walls in their original locations, guiding where to dig next. They're even using AR smart glasses to capture photos and take notes hands-free while actively digging. Game-changer. But here's the most exciting part: For the first time ever, a team is using MR and AR headsets to support their excavation work. This "vision for the future" is enabling brand new ways of studying the past. Imagine being able to compare 3D scanned pottery fragments with real ones, even when the artefacts are inaccessible in museums. In the future, AI could match these pieces by shape alone. This isn't just a breakthrough for archaeology—it's a whole new era of preserving cultural heritage. And you're witnessing it unfold right now. #ArchaeologyRevolution #ImmersiveTechExcavation #PreservingThePast #JamieBykovBrett #MetaHub

  Stellarium:  Now that is a purty gentle, paw-paw! Which astronomy software program has caught with me, I imply, muchachos. Which isn’t what this one was imagined to be about. It was supposed to concern my ongoing re-exploration of the Moon. Or possibly, if I obtained terrible sanguine, getting my large 6-inch refractor and Losmandy GM811 out of mothballs. Alas, with the month working out, I discovered myself underneath sometimes grey and stormy spring Gulf Coast skies. So, what we’re going to speak about this morning is which astronomy software program I’ve discovered enduringly helpful over time and which I haven’t. Nota bene:  this time we’re speaking solely about planetarium/planner software program…another time we can jaw about imaging and guiding applications and stuff like that. What Has Stuck Stellarium I used to be terrible skeptical about this astro-soft for the longest time. It was terrible purty, certain. Very. And amazingly responsive on modest PCs regardless of that stunning depiction of the sky. However it simply didn’t appear to supply a lot past that. Hell, it wouldn’t management a goto scope, and its number of deep sky objects was fairly restricted. It was an “armchair astronomer” kinda factor, I reckoned. Not anymore. This freeware program has developed right into a highly effective instrument for doing many issues in newbie astronomy. It has built-in telescope drivers, ASCOM compatibility, and an enormous variety of DSOs. Stellarium’s visualization of the sky is prettier than ever, and the efficiency hasn’t suffered. Cartes du Ciel Cartes du Ciel. As fairly as Stellarium? No, however very helpful! I shouldn’t need to let you know it is a perennial favourite of mine. It has been since my late buddy and proficient observer and author Jeff Medkeff informed me I ought to take a look at it many a protracted 12 months in the past. It really works merely and effectively and gives all of the options most working amateurs may need. Howsomeever. Perceive that is available in a reasonably plain bundle. Oh, it has been regularly up to date by writer Patrick Chevalley, and doesn’t appear to be a refugee from the early 90s, however it doesn’t fear about an excessively life like depiction of the sky. Its show is obvious however clear and it is legible, which is usually a very good factor out on a darkish observing subject. Skytools 3 Writer Greg Crinklaw has had Skytools 4 out for numerous years. However you already know what? I by no means obtained pleasant with it like I did with 3.  Perhaps that’s as a result of the model of ST4 I’ve is the imaging taste and is far extra highly effective and advanced than simpleminded moi wants.  ST3 was the software program that carried me by means of the Herschel Undertaking, my quixotic quest (that is alliteration day) to watch all of the hundreds of deep sky objects found by Sir William Herschel. Skytools 3 gave me all of the instruments

Soon FY826 (Observationskursus i Astronomi) will fly off here at SDU. Still a lot of preparatory work to be done, but among other topics the students will create their own analemma (here demonstrated for an observer at latitude 41 degree north; horizontal line on the world map). Observing an analemma provides direct empirical evidence for Earth's orbital eccentricity in addition to Earth's axial tilt relative to the ecliptic. Be aware: observing a real-world analemma takes a minimum of one year and some engineering skills (your hands need to be attracted to screwdrivers, a Raspberry Pi, glue and other tools). For the class, we use online-simulators provided by (https://lnkd.in/d9qZrwWX) to create GIF animations and visualize the motion of the stars and the Sun. Can you spot the analemma in the animation? Looking forward to it. The course is organized in tandem with my colleagues Mikkel Theiss Kristensen and Mads Toudal Frandsen.

"Donald Olson, an astrophysicist and forensic astronomer at the State University System Regent, has used his scientific training to determine where Vincent van Gogh’s iconic 1884 work, Lane of Poplars at Sunset (now held by the Kröller-Müller Museum in the Netherlands), was in fact painted. "Olson first had to find the specific painting’s specific site. 'If we could identify the lane on 19th-century maps, then we’d be able to establish the compass direction of the road appearing in the artworks,' he explained in a press release. 'Next, we could use astronomical calculations to determine the date when the disk of the setting sun aligned as Van Gogh portrayed it.' "The next phase of his research also involved some art-historical sleuthing. He referred to the 1928 catalogue raisonné on the artist compiled by Dutch art historian Jacob Baart de la Faille, in which Lane of Poplars at Sunset was identified as painting F123. However, upon further investigation, Olseon realized that another painting, F122, known as Lane of Poplars in the Autumn today, showcases an earlier fall scene which is clear from the foliage and number of leaves on the trees. Lane of Poplars at Sunset, though, features trees that are sparser and lacking the robustness of the other trees. :Looking further into the correspondence from this period, Olson was then able to determine a time frame based on the image and the number of leaves left on the trees. With those dates in mind and through the use of planetarium software, Olson concluded that “the sun set in the southwest, in the range of azimuths, or compass direction of a celestial object, between 240 and 244 degrees.” "From there, Olson and his team hunted down more historical data to further pinpoint the location, namely 1883 maps that detailed the layout of Nuenen and neighboring villages (Nederwetten, where Autumn was painted, did not match the setting of Sunset). Three candidates were picked out—Hoekstraat in Nederwetten, and Braakweg and Weverstraat in Nuenen—before the latter was eventually determined to be the location for its length, which could have accommodated the number of trees Van Gogh depicted. "Astronomical calculations showed the setting sun would have been visible setting over Weverstraat on November 13 and 14 in 1884, with historic weather records confirming the day’s clear skies would have made it conducive for the artist’s plein air work."

📸 I'm one of those people... who never deletes photos off my phone. Ever. 📸 I also fill up my hard drive with multiple versions of the same report. (I might need to see those revisions I made 27 days ago at 1:46 pm. I’ll be prepared.) This accidental fieldwork photo is from a couple years back. Recently, my iPhone reminded me of this. No idea- maybe I dropped my phone? To this day, I remember how it felt when the 60-degree-below-zero wind chill froze my eyelashes together after jumping out of the truck. The throbbing pain in my fingers despite the eleven pairs of gloves I bought while searching for a pair to keep my fingers warm enough, so that I could take field notes. I also remember my incredible field crew, who never once complained to me <Rockstars!> They just kept going, and no one got hurt or frostbite. Because fieldwork was that amazing. After months of fieldwork, in the harshest conditions I've worked in the Northern Hemisphere, this project is where I remembered- I'm a field archaeologist. And always will be. Afterwards, I flew home. Looked for a job in CRM and resigned from my university job. Best career decision ever, and although I still miss my students, I now get to teach in other ways. Listen to your gut. It is trying to tell you what is best for you. Trust yourself, because you know you best. #archaeologyisnonrenewable #archaeologicalsurgery #geoarchaeologyisarchaeology #yearofgeoarchaeology #culturalheritage #STP #geoarchaeology #deeptesting #culturalresources #archaeology #crm #coring #paleosols #geomorphology #buriedAhorizons #alluvial #paleolandscapes #deeptesting #nevergiveup

DANG... it looks like a bomb went off in this place?! ... and the way to find balance in the messes of playful spaces. One of my past Executive Directors always called it Visitor Archeology, while others have mentioned 'breadcrumbs of play'... but how do we find balance between the mess of loose parts everywhere and the sterile 'do not touch' feeling of a perfectly tidied space with everything in it's place?? 🤔 It's all about prepping spaces with your guest in mind. Whatever you call it this approach can revolutionize how visitors interact with your museum. ⚡️ create inviting environments that spark curiosity 💐 thoughtfully arranging exhibits .... and most importantly.... 🦕 leaving subtle evidence of previous visitors' discoveries (archeology 😉) This technique not only saves time but also inspires new guests to explore and interact without intimidation. It's about creating a silent invitation to engage, learn, and have fun. I also love that it pay homage to the creators that came before with the display of their creations... that will most certainly soon be modified too! How do you prepare your museum spaces to maximize engagement? P.S. If you like this thought of Visitor Archeology... I gathered a bunch more visitor engagement tips in my Museum Engagement Prompt Cards. Go grab yourself a set. cards.inspired-impact.com
