  2. Typically modest the #Draconids might break tradition this year! Forecasts predict a burst of 150–400 #meteors per hour on October 8. Moreover this may be the last Draconid outburst until 2078! 🌠🐉 #Space #Astronomy #MeteorShower #SkyWatch #DraconidShower #Stargazing #Cosmos #CelestialEvent #Science

  3. From a location in Estes Park, under a clear, half-moon lit sky, between 9:00 and 9:02 local time I saw a bright red object with no aircraft strobe appear suddenly almost directly overhead, then extremely rapidly silently cross the sky in a southeast direction. I was able to track the object until it went below the horizon, bearing 160°

    Nothing shows up on flight radar. Is there any open source radar that might have shown the object? NOAA weather radar is down at the moment. Could it have been #starlink?

  4. #SkyWatch #Astrophotography #StarTrails This photo is pointed at Polaris aka the North Star which was used historically for navigation because it moves very little while the rest of the sky rotates. I exposed this photo to preserve natural star colors but set up my intervelometer incorrectly so there are gaps in the trails which i decided looks cool. #StillLearning

  5. #SkyWatch #Astrophotography IC405 aka the Flaming Star Nebula is an emission and reflection nebula 1500 light years away in the Auriga constellation. The reflection nebula is the bluish area around the star AE Aurigae. This is the first time that I have been able to bring out the detail of the reflection nebuloaity amidst the stronger hydrogen emissions. #StillLearning

  6. #SkyWatch #Astrophotography I've been learning some new processing techniques to bring out oxygen and sulfur in my images: hydrogen in the red part of the light spectrum, oxygen in the blue, and sulfur in the orange. My images tend to be mostly quite red because hydrogen is so abundant. Using these new techniques, I reprocessed exposures from early September of the North America Nebula in what is known as the Hubble palette of colors. #StillLearning

  7. #SkyWatch #Astrophotography M45 aka Pleiades is an open star cluster 444 light years from Earth near the Taurus constellation. It contains over 1000 hot B-type stars that have formed within the last 100 million years. It is surrounded by space dust which reflects the blue light of the stars and makes it appear as a blue smudge. This image is 48 five minute exposures that I captured under partly cloudy skies and processed using some new to me techniques. #StillLearning

  8. #SkyWatch #Astrophotography The #Rosette Nebula is 5200 light years away in the #Monoceros constellation. It is about 130 light years in diameter and is home to many clusters of newly formed stars. It has a mass about 10,000 times that of our Sun. This image is 15 five minute exposures captured over two mornings just before sunrise

  9. #SkyWatch #Astrophotography SH2-132 is a faint emission nebula about 10,400 light years away in the Cepheus constellation. The two stars that are believed to be ionizing the gasses of the nebula are rare Wolf-Rayet stars, which are hotter than almost all other stars. They have depleted almost all of their hydrogen and are fusing helium or heavier elements at their core. They produce strong stellar winds as a result. #StillLearning

  10. #SkyWatch #Astrophotography The #Rosette Nebula is a hydrogen II area 5200 light years away in the faint #Monoceros constellation. In the center of the nebula is #NGC2244 which is an open cluster of hot young stars. This image is 19 five-minute exposures captured in the wee hours of the morning when the #Rosette was above the horizon in NH.

  11. #SkyWatch #Astrophotography The blue supergiant star #Alnitak is 1250 light years away and is actually a triple star system. It serves as the easternmost star in Orion's Belt. The #Flame Nebula on the left and the #Horsehead Nebula on the right are emission nebulae energized by Alnitak. The area rises this time of year after 2am at my location. This image is only 10 five-minute exposures captured on a partly cloudy morning that caused me to throw away 25 additional images. #StillLearning

  12. #SkyWatch #Astrophotography The #Orion Nebula is about 1350 light years away and is among the most studied objects in the night sky. Over 700 stars are in various stages of formation within the nebula, including the four young stars of the Trapezium Cluster. Evidence suggests there is a black hole 100 times the mass of our Sun at the center. The nebula is considered a beginner target but is challenging to photograph well. This image is 100 thirty-second exposures. #StillLearning

  13. #SkyWatch #Astrophotography The #Heart Nebula is about 7500 light years away in the #Cassiopeia constellation. This image of 67 five-minute exposures focuses on the center of the Heart, on the star cluster whose winds are carving out the Heart. Melotte 15 is a young cluster at about 15 million years old and contains several stars with masses up to 40 times that of our Sun and many with masses a fraction of that of our Sun. #StillLearning

  14. #SkyWatch #Astrophotography The #Wizard Nebula aka NGC7380 is 8500 light years away in the Cepheus constellation. It is between 4 and 11 million years old and is extremely difficult to observe visually. This image is from two nights, September 4 and 14, which I combined for a total of 6.5 hours of exposure. I threw out about 3 hours of exposure due to clouds. #StillLearning

  15. #SkyWatch #Astrophotography The #Horsehead Nebula aka #IC434 is a dark nebula near #Alnitak the easternmost star in Orion's Belt. The red hydrogen of the nebula is though to be excited by Sigma Orionis, the bright star in the upper right. The nebula doesn't rise until 2am at my location right now and I had to throw away many exposures due to clouds so this image is only 17 five-minute exposures captured in the wee hours this morning. #StillLearning

  16. Day 1624 #DailyPhoto #SkyWatch #Astrophotography The #Jellyfish nebula aka #IC443 is a supernova remnant about 5000 light years away in the Gemini constellation. The remnant is about 50 arc minutes across. In comparison, a full moon is 30 arc minutes across. The bright star is #Propus aka Eta Geminorum and is actually a triple star system. #StillLearning

  17. #SkyWatch #Astrophotography If you zoom into the right side of this image, you will see NGC7635 aka the #Bubble, an emission nebula in the constellation Cassiopeia. The Bubble is created by stellar winds from its central star, which is about 44 times the mass of our Sun. The open star cluster #M52 is in the lower left. It is 158 million years old and contains 1200 times the mass of our Sun. #StillLearning

  18. #SkyWatch #Astrophotography The #Cocoon Nebula aka #IC5146 is a star nursery about 4000 light years away in the #Cygnus constellation. The central star that lights it is only 100,000 years old. The nebula is surrounded by a dark lane of dust called Barnard 168 which gives it the appearance of having a dark tail. There are thousands of young stars in this complex. #StillLearning

  19. #SkyWatch #Astrophotography The #SoulNebula aka #IC1848 is an emission nebula in #Cassiopeia about 7500 light years away. The center of the nebula is being carved out by radiation emitted by stars found there. This creates finger-like plumes of gas, called "pillars of creation", that can be seen along the edges. The gas is increasingly compressed to form new stars at the end of the plumes. This image is 70 five-minute exposures (5 hours and 50 minutes). #StillLearning

  20. #SkyWatch #Astrophotography The #CocoonNebula aka #IC5146 is an emission nebula about 4000 light years away and about 15 light years across. It is a star formation area with hundreds of young stellar objects having been identified. It is surrounded by Barnard 168, a dark nebula that can be seen trailing off to the right in this image of 15 five-minute exposures. #StillLearning

  21. #SkyWatch #Astrophotography The blue star in this image is Gamma Cassiopeia, the bright star in the center of the W shape of the #Cassiopeia constellation. The Ghost of Cassiopeia aka #IC63 is the emission nebula to the left of the star. #IC57 is the blue reflection nebula above the Ghost. Reflection nebula aren't hot enough to generate their own light but instead can be seen only by their reflection of light from nearby stars. #StillLearning

  22. #SkyWatch #Astrophotography The #EagleNebula aka #M16 is a young open cluster of stars about 5700 light years from Earth. The cluster contains approximately 8100 stars and includes the active area called the Pillars of Creation, made famous by a Hubble Telescope image. The nebula rose at about 10pm last night and set at about 12:30am but is only visible for me for about an hour and a half which is the longest it is visible all year. This image is 16 five minute exposures #StillLearning

  23. #SkyWatch #Astrophotography Yesterday's daily photo was a crop of this one which shows the #Bubble Nebula on the right and the open star cluster #M52 on the left. M52 is a large star cluster in the #Cassiopeia constellation. The central portion of the cluster shows very little interstellar matter. The current theory is that this matter was blown away by many supernova explosions early in the life of the cluster. The cluster is estimated to be more than 150 million years old. #StillLearning

  24. #SkyWatch #Astrophotography I went back to some data I captured in February to reprocess it for practice. The #FlamingStar Nebula is an emission and reflection nebula in the #Auriga constellation. It is about 1500 light years from Earth. The bright yellow star is called 16 Aur and is actually a triple star system with the brightest of the three being 5 billion years old. #StillLearning

  25. #SkyWatch #Astrophotography #NGC7822 is a large emission nebula about 3000 light years from Earth in the constellation #Cepheus. The bright nebulosity is a star formation area comprised of mostly hydrogen. It is illuminated by its very hot central star, which is 100,000 times more luminous than our sun. #StillLearning

  26. #SkyWatch #Astrophotography #NGC7822 is a large diffuse emission nebula about 3000 light years away in Cepheus. It is the site of active star formation and is home to one of the brightest nearby stars V398 Cep. V398 Cep is a red M5 star and is more than 77 times larger than our sun. Because it is so large and bright, it is expected to explode relatively quickly in a few thousand years. #StillLearning

  27. #SkyWatch #Astrophotography #NGC2264 is part of the #Monoceros region of the Milky Way and contains 4 nebulae that are between 2300 and 2700 light years from Earth:. The #ConeNebula is on the far left. The #ChristmasTreeNebula looks like it is lying on its side with the Cone at its top,. The #SnowflakeNebula is bluish white. And the #FoxFurNebula is on the far right. This image is 17 three minute exposures that I captured Friday night stacked with calibration frames. #StillLearning

  31. #SkyWatch #Astrophotography The #RosetteNebula again. Astrophotography requires an interesting mix of skills. I spent some time yesterday working on my processing skills and learned some new techniques. For this image, I stacked 45 three minute exposures with calibration frames. I then separated the resulting image into its 3 separate color channels--red, green, and blue--and processed each color separately. The result is cleaner and sharper details . #StillLearning

  32. Day 1454 #DailyPhoto #SkyWatch #Astrophotography The #RosetteNebula is 5000 light years away in the Monoceros region of the Milky Way. #NGC2244 is the young star cluster at its center that is ionizing the surrounding gas cloud. I was able to capture 45 three minute exposures before the clouds rolled in. I also integrated 20 bias, 20 dark, and 20 flat frames. #StillLearning

  33. #SkyWatch #Astrophotography These 3 galaxies are called the #LeoTriplet because they are part of the Leo constellation. They are 35 million light years from Earth. The top galaxy is #M65, the one on the left is #M66, and the one on the right is #NGC3628 also known as the Hamburger galaxy. I'm really pleased at the detail I was able to pull out of each galaxy, especially the blue star clusters in M66. #StillLearning

  34. #SkyWatch #Astrophotography The #Virgo constellation is full of galaxies. The central galaxy in this photo is #M86 which contains about 3800 globular clusters of stars and its halo contains a number of dwarf galaxies that have been disrupted and incorporated into M86. Other galaxies in this image include M84, NGC4388, NGC4387, NGC4407, NGC4402, NGC4425, and my favorite, the interacting pair at the bottom, NGC4435 and NGC4438 known as the Eyes Galaxies. #StilLearning

  38. #SkyWatch #Astrophotography #IC1396 is a large cloud of ionized gas about 2400 light years from Earth in the #Cepheus constellation. It contains the #ElephantTrunk nebula, a long dense pocket of dust and gas just to the left of the bright blue star at its center. Our nights have been so cloudy that I got up at 3:30 this morning to capture two hours of exposures while the sky was finally clear. IC1396 could use a lot more exposure time to really bring out the colors. #StillLearning

  39. #SkyWatch #Astrophotography This image of a small part of #UrsaMajor shows at least 4 galaxies: #Bode's (M81), #Cigar (M82), #NGC3077, and #NGC2976 . These galaxies are between 11 and 14 million light years from Earth and each contains billions (with a b) of stars. I had planned to spend a couple of hours capturing this image but the clouds rolled in after 20 minutes. #StillLearning
