  1. 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

  2. #SkyWatch Weeks of overcast skies with no chance for #Astrophotography but it's a clear day today after a huge spring snowstorm yesterday. #AnotherSunrise #SpringInNH

  4. #SkyWatch #Astrophotography The California Nebula is a large, faint nebula in the #Perseus constellation. It is about 1000 light years away. Its fluorescence comes from the hydrogen beta gas being energized by O7 star #Menkib which is the bright blue star in this image. I salvaged about 3.5 hours of exposure from a few nights ago when I forgot to turn my dew heater on. This explains why I wasn't able to get much detail in the nebula itself. #StillLearning

  9. #SkyWatch #Astrophotography I have posted photos of the #CrescentNebula before but not ones created with my 250mm lens. This wider field of view shows the Crescent (lower right corner) amidst the hydrogen gas clouds of the #Sadr region in the center of the #Cygnus constellation. The Crescent is a shell caused by colliding gasses after a star explosion and is 5000 light years from Earth. #StillLearning

  14. #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

  16. #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

  18. #SkyWatch #Astrophotography #NGC7380 is an open cluster of young stars in the #Cepheus constellation. The surrounding nebula is about 7200 light years away and is sometimes called the #Wizard Nebula. This image is nearly 5 hours (29x600 seconds) of exposures that I captured last night. #StillLearning

  19. #SkyWatch #Astrophotography This image of the #Dumbbell Nebula aka #M27 is a combination of exposures of 120 seconds, 180 seconds, and 300 seconds using a new-to-me technique to get detail in all parts of the nebula. The Dumbbell is about 1200 light years away in the #Vulpecula constellation. Formed sometime less than 14,000 years ago when nuclear fusion stopped in the core of a star like our Sun, it was the first ever discovered planetary nebula in 1764. #StillLearning

  21. #SkyWatch #Astrophotography #M27 aka the #Dumbbell Nebula is a planetary nebula in the #Vulpecula constellation about 1360 light years from Earth. It was created about 10,000 years ago when a star similar to our sun ran out of fuel and expelled all of its gas and collapsed into a white dwarf. I tried a new process for this image, taking exposures of different lengths to try to capture various kinds of details in different parts of the nebula (with only moderate success). #StillLearning

  23. #SkyWatch #Astrophotography #Sadr is the bright star in this image. Also known as #GammaCygni it is the central star of the cross that makes up the #Cygnus constellation and is about 1800 light years from Earth. It is not the source of the large emission nebula #IC1318 that appears to surround it. #IC1318 is about 5000 light years from Earth and is sometimes called the #ButterflyNebula #StillLearning

  28. #SkyWatch #Astrophotography The #GammaCygniNebula is 4000 light years away in the #Sadr region of the Milky Way. This image represents an instance in which a bigger telescope is not always better for astrophotography. With my 715mm I could only capture half of the nebula. The other half is on the other side of the dark nebula in the lower right. With the other half, the nebula looks like a butterfly. I think this half looks like a flying squirrel. #StillLearningDay

  31. #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
