Theta Muscae region - SNR G304.4-3.1

One of my new favorite regions, the filaments are so delicate and beautiful! In the Theta Muscae star system, the SNR G304.4-3.1 is a Supernova Remnant(SNR) in the constellation Musca, roughly 7400 light years away. The system contains a Wolf Rayet star and two large companions.
The Wolf Rayet star is the second brightest Wolf Rayet at Magnitude 5.5.
The delicate blue regions of the SNR are primarily OIII and are pretty faint and the red regions are rich in Hydrogen Alpha. The remnant is thought not to be directly connected to Theta Muscae.

Imaged in Ha OIII and RGB on the Planewave DR 350 at Observatorio El Sauce, Chile.
Processed by me using Pixinsight and Photoshop.

The details on the OIII were so delicate and the star field so dense it swamped them! This image even with the dense star field is mostly reduced stars!!! I was so tempted to go starless but I did decide to then tone down stars around the OIII and tried to balance the two. The stars themselves are so pretty!

Thank you to Mike Selby or this amazing data!

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.
