Description

Shot this while waiting for the Spaghetti Nebula to get above my parents house. It's only a hour of hydrogen-alpha data, and the noise shows it, but I'm pleased with how this turned out. I have no plans on adding Oiii or RGB data to this (this lens is ass even stopped down). This is a lot wider of a FOV than [my previous images of the [Heart](https://www.reddit.com/r/astrophotography/comments/degpmw/the_heart_nebula_in_bicolor_starless/) and [Soul Nebulae](https://www.reddit.com/r/astrophotography/comments/9tibbs/ic1848_the_soul_nebula_in_hargb/). I've also made an [annotated version](https://i.imgur.com/M9ROv3w.jpg) and a [starless version of this image using StarNet](https://i.imgur.com/xCcf1Mm.jpg). Captured on December 31st, 2019 from a bortle 6 zone.
