In the heart of Cygnus, near the bright star, Sadr, is the Butterfly Nebula (IC 1318). It flies an arc across the sky on summer evenings in Northern California. While its wings appear to be two separate nebulae, it is actually a single nebula bisected by a 20 light-year long dark lane of dust (LDN 889) that forms the body of the butterfly.

This image is composed of a strong Ha emission signal, and weaker SII and OIII signals. Relentless night time overcast here in Monterey meant that I was able collect only a few hours of data at a time during occasional and brief weather break over the last two months. This week I finally got the last couple of hours of the 20 hours total needed for this image. For me, it was worth the trouble.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
