- Astrophotography Imaging NGC 2359, Thor's Helmet Nebula:
Using Electronically Assisted Astrophotography, we unveil the mystery of NGC 2359, also known as "Thor's Helmet." This Nebula derives its name from its appearance, that of a Viking Helmet. The shape is the result of a Wolf-Rayet Star located inside the nebula. A Wolf-Rayet Star is a massive star that is approaching the end of its life cycle and has burned through its primary fuel source, hydrogen, and is beginning to fuse the heavier elements within it. This in turn results in tremendous heat, radiation, and powerful stellar winds. The Wolf-Rayet star responsible for the forming of Thor's Helmet shines an incredible 230,000 times brighter than our sun. And the powerful stellar winds have pushed the molecular space dust away from the star, creating a sort of bubble, or "helmet" shape. The copious amounts of radiation have ionized the entire nebula, causing the various elements that comprise it to radiate light. The nebula itself, with the "helmet" in the middle, has the shape of horns, that combined with the nebula the appearance of a Viking Helmet.
Thor's Helmet, NGC 2359, is am amazing 30 light years in diameter. However, it is not an easy target to capture as it lies somewhere between 13,000 and 15,000 light years from earth. Be that as it may, we do indeed capture it and managed to produce an image that we are quite pleased with. Using electronically assisted astrophotography, we are able to see the image come to life on the computer screen as each sub-exposure is stacked to the previous sub-exposures, revealing more detail, color, and light.

I love the story of Thor's Helmet as it is "traversing through the galaxy." You have done a magnificent view of so many stars. Shadow is a lucky dog to have so many wonderful adventures.
Hello Andrea! Great to hear from you! I owe you a photo of The Whirlpool Galaxy.
Great image Lance!! Amazing what you can do out in your skies in so little time!
Thank You, Doug! I look forward to the images you are going to be able to produce with that new beast of yours!
@@adventuresofshadowdog I’m excited to get the system running. Only 5001 more things to do!!
Another awesome video, Lance! Thanks for always sharing with us.
Thanks Marla!
Awesome image, brother. I would love to get some time in the desert for imaging. Must be fun getting out there.
Thanks! There is something therapeutic about being out there alone in the desert under the stars. Really helps keep me sane in an otherwise insane world. Thanks for watching and commenting!
@@adventuresofshadowdog You are alone as long as you have Shadow with you.
Great video and stunning image. That is now the new screensaver on my phone.
Wow! Thank you!
Yeah that’s it. That is one of the good walls to climb on down there.
While so much content is devoted to furthering the tragedy and animosity in the world, this channel is always such a great antidote - always a source of beauty and insight. Really appreciate the work you do (though that statement doesn’t do it justice)!
Eric, I cannot thank you enough for leaving such a wonderful comment. Today was one of those days, as we all can have from time to time, that I was really feeling low for multiple reasons. Then your comment popped in just before I am going to bed. Timing could not have been better! Thank You! 🙏
Lovely Image! Thanks for always being so positive and inspiring. It takes tons of work to make these videos and I really enjoy all of them!
Thanks so much for the encouraging words. Comments such as yours make it all worthwhile! Shadow agrees and his tail is whirling right now!
Wow agian. That is beautiful and amazing. Very talented.
Thank you so much Colleen!
All so interesting . You explain it so well.
Please check your email. Lol.
Thanks Jan! I did respond to your email. Loved, Loved, Loved your poem!!!!
What a gorgeous process. The end result is, actually, quite stunning.
Thanks so much Kyle! Sometimes they turn out really well, sometimes so so, and sometimes I come home with nothing. Lots of variable factors at play. This one turned out really well by my standards. Thanks for the kind words!
Is that prophesy wall in the background?
I’m not sure. It’s right across from the reservoir just down from Veyo volcano. Does that right a bell?
I just found this channel as I'm just getting into astrophotography. I really like that also you teach about the object you're photographing, great for a beginner like me. Subscribed!
Thanks @calabrais! I love to make this videos for multiple reasons. Introducing people to astrophotography is one of them. Admittedly, I am an amateur astrophotographer that still has a lot to learn in a hobby that seems endless. I learn a lot from AstroBackyard, Dylan O'Donnell, The Narrowband Channel, Cuiv The Lazy Geek, Wido's Astroforum, Galactic Hunter, Nebula Hunters, etc. If there is anything I can help you out with, feel free to reach out via email: Lancesnarr@gmail.com. Thanks for watching and commenting!
@@adventuresofshadowdog You're the best, that's really appreciated. I probably will bother you when I have a question haha Stay awesome.
Work.... Luckily I live 5 minutes from work. Luckily I have to start at 9, but if I start at 10 its okay too. So if the skies are clear I can take my time to play with my telescope. Thanks for the video and the photo Lance and Shadow. Saludos from Spain, Rob.
Hi Rob! Great to hear from you. My work schedule is very similar to yours. So it helps a lot when I’m out late. How are the skies in Spain these days? Also, Shadow barks a “hi”.
@@adventuresofshadowdog At the moment we have clear skies, but there is a lot of wind. But for tonight my telescope is already ready. I have made a pier, so setting up is easy.
Would love to see it! Maybe email a pic? Also, Shadow wants me to tell you thank you for the last email. I’m keeping him extra safe!
Very nice. Thanks for sharing.
Thanks for watching!
Thanks👍
Appreciate the comment and thanks for watching!
Amazing
Thanks Paul!
Thus says the LORD, the King and Redeemer of Israel, the LORD of Hosts: “I am the first and I am the last, and there is no God but Me.
You are 100% correct. Thor and the other “gods” are mythical.
