This is my next to last image from the observatory in West Virginia. While I was working on the M45 image I acquired data on the cone when the moon came up. I ended up with 13 hours total with SII slightly edging out the other filters.

The nebula is about 2,700 light years distant and is large both in apparent and absolute size. This image covers roughly 1.5 degrees across.

This is presented in an HSO palette and was a bit of a challenge to process. The entire field had at least some nebulosity. I’m pretty sure the faint nebulous stuff in the image is actually nebula and not noise or light pollution gradients since I see it in other images.

For the technical details see the astrobin version.
