Sh2 222 Hydrogen Alpha RGB AKA NGC 1579 and the "Trifid of the North"

We did this in RGB a few years ago with Rob's RC10:

But I thought there must be HA here, so I re-shot it using my standard Sh2 techniques. Bottom line there is HA.

Here are the notes from Galaxy Map:

Also called NGC 1579 and informally the "Trifid of the North", this dusty reflection nebula contains a cluster of about 5 bright B class stars and 35 other stars. The cluster is dominated by the massive young star LkHα 101.

Also called NGC 1579, this reflection nebula and dust cloud contains a cluster of about 5 bright B class stars and 35 other stars. The cluster is dominated by the massive young star LkHα 101. It is not an HII region. [Well IMHO there is HA]

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.
