I just noticed last night after adding more OIII subs that these two nebula look like part of the same system and appear to be connected to each other. I’ve tried to search for more information, as I’m assuming it’s well documented somewhere… I’m trying to learn more and it would help if I knew what these tubular nebular systems were called. If anyone could point me in the right direction it would be greatly appreciated https://astrob.in/zmqhiy/I/ |

| https://astrob.in/qimo09/0/ shows that all form part of one large soup of glowing hydrogen being Sharpless 230 but there doesn't seem to be much written about it other than it, very large. but even then, if you wide field Cygnus, pretty much the whole constellation glows brightly. |

Hi, as usual the internet helps a lot . Flaming star nebula IC 405 is reported on Wikipedia to be at a distance of around 1.500 light years, while NASA reports a distance of about 10.000 light years for the spider nebula IC 417. So they are not really connected. Of course they "share the same path" at the sky because in terms of RA and DEC they are close to each other. Just "google" IC 405 and IC 417 for more information on these nice objects. Have fun and best regards Wolfgang |

Chris Bailey: Hi, Thank you @Chris Bailey and @kuechlew for the reply, after doing some research today I found more Information about these bright rimed star forming “globules” than I’ll ever be able to understand 🤯 “The bright-rimmed globules in the local environment of V582 Aur probably belong to the dark cloud LDN 1516. Our results suggest that star formation in these globules might have been triggered by the radiation field of a few hot members of Aur OB 1. The bolometric luminosity of V582 Aur, based on archival photometric data and on the adopted distance, is 150–320 L⊙.” It’s an interesting read, (from the small percentage I can comprehend) many of the Ha star forming areas listed in the article are listed in the plate solved annotations in my image! https://academic.oup.com/mnras/article/468/2/2325/3070433 |
