Happy #EarthDay! In honor of preserving this Earth, we'd like to call attention to the ways in which light can negatively impact humans and animals. We'd also light to share how you can truly make an impact by utilizing healthy light and being mindful of WHEN you use it.
Studies show that the blue light found in most artificial light sources has biological and physiological impacts on humans, animals, and even plants. While the lighting revolution has prolonged the hours of light ready available to humans and essentially changed how our society functions, there are some serious downsides to consider. The increased levels of light pollution and sky glow (luminance of the night sky, apart from natural light sources such as the Moon and visible stars) in night-time environments threatens entire ecological systems and makes it much more difficult (and often impossible) to see the night sky clearly.
Animals truly do have a hard time with unnatural lighting. Birds, for example, rely on the moon and stars for navigation when they migrate. With the extended hours of light in today's offices, it's unfortunately a lot more common for these birds to collide with brightly-lit skyscrapers at night. Turtle populations have also notably plummeted over the years, partly because of urban lighting that disrupts nesting sites. Hatchlings use moonlight reflecting off waves to guide them towards the water. With the overabundance of urban lights, and tourists running on beaches with flashlights, many turtles either head inland or move toward the water at the wrong time -- into danger nonetheless. In fact, researchers have found that 1 in 3 turtle hatchlings move toward city lights rather than the sea. (Continued in the comments below!)

Happy Earth Day! 🌍 Did you know that light pollution has significant impacts on wildlife and the environment? Check out the link in bio to learn how light pollution impacts insects, birds, fish and sea turtles, and learn how YOU can get involved. What better day than #earthday to join the movement to protect the night?

Happy Earth Day!!! 🌎♥️ It is so overwhelming to think about everything that I want to say/ promote on this day (and every day!) But I want to take a moment to be happy for all of the changes people have taken in the last year!! 😊 So many people are now living a plant based diet🥬, cutting down on eating meat (We have significantly in the last year)🐮, learning about pollination/bumble bees/animal extinction🌷🐝🐋🦏, conserving power and water (my own dad invested in solar panels!) 🛁💡and even businesses have taken action to eliminate single use plastic♻️!! Yay us!! While there’s still a longgg way to go, let’s be happy about how far we have came too! @leonardodicaprio@gretathunberg@berniesanders Thank you for being 3 of my top influencers and for using your voice to educate others 💘!! Let’s keep the planet green for our future babies’ babies and long after that! 🌱🌎 #globalwarming#oceanpollution#energyefficiency#extinction#airpollution#soilpollution#lightpollution#educate#recycle#read

#روز_زمین تنها تبريك گفتن به هم نیست، یادآوری پاسداشت #زمين و اصلاح سبک زندگیمونه، تلنگري است براي شناخت بيشتر محيط پيرانمون، يادآوري اينكه ما و كره زمين با هم گره ي كوري خورديم.
ما بايد با محيط زيستمان تعامل سازنده اي داشته باشيم. بايد قوانينش را به خوبي بشناسيم و به آن ها احترام بگذاريم.
ما بايد بدانيم قطع درختان #زاگرس براي #كشاورزي و ذغال چه تاثيري در #سيل داشته است؟
بايد بدانيم حريم #رودخانه كجاست؟
حق ماست كه بدانيم #سدسازي ها چه تاثيري داشته اند؟
بايد آگاه باشيم كه چراي بيش از حد دام، باعث كاهش جنگل ها شده است،
بايد بدانيم كه مكانيزم دفع #زباله در كشور چه اوضاع اسفناكي دارد.
بايد انساني آگاه به محيط زيستمان باشيم تا #مطالبه هاي به جا و درستي داشته باشيم.
بايد بدانيم آبخوان داري چيست؟ بايد بدانيم كه شكار بي رويه #پرنده ها باعث شده كه امروز از هجوم #ملخ ها در جنوب كشور بترسيم.
همه ما بايد محيط زندگي خودمان را به خوبي بشناسيم، همانطور كه پدران و مادران ما ميشناختند و از آثارشان پيداست.
Very excited to finally get this bad boy modded!! Will be sending it in about a week so hopefully I will get it back in time to collect some data on a few targets before they set for the year. This is a full spectrum modification that removes the red and infrared filter from the camera, essentially leaving a clear path for all light to travel directly to the sensor meaning I will be able to capture that sweet hydrogen alpha in the sky. However, the removal of these filters means that an overload of infrared will be blasting the sensor, causing stars to appear bloated. That's where all these Astronomik and HUTECH filters come in - they clip directly into the camera body and have cut offs at the infrared wavelength so no light in that spectrum gets through, meaning I'll gets lots of signal from nebulae without overexposed stars. With additional bonuses to reducing light pollution, I'm looking forward to trying these out with a newly dedicated astro camera in my set up.
