NGC 7023: The Iris Nebula

First light on the Iris Nebula turned out fantastic!

I’m lucking out with back-to-back-to-back-to-back-to-back clear spring nights around a new moon. Can’t ask for anything better. So each night, I’m taking my time with targets rather than trying to cram too much into my sessions.

This reflection nebula enjoyed nearly 5 hours of imaging, giving me a better choice of images to stack and blend. This has a huge impact on my astrophotography, as more images means less noise and a greater ability to pull faint detail.

And the Iris Nebula has a lot of detail to manage. From the bright inner core, fueled by a cluster of newly formed blue stars, to the large outer dust lanes this nebula has something for everyone. My astrophotography post-processing skills have progressed a lot during isolation… a year ago the core would have been blown out or the dust trails wouldn’t show up. I’m very happy with this output.

Onto night 3!
