Propeller Nebula: Bicolor HOO

A HaOIII bicolor of what I think is a pretty structurally interesting area. I have grown to like bicolored images of emission nebula becuase I think its a lot closer to the visible RGB palette. I know it's not exactly the same, but it crtainly is reminiscent of RGB. This image has very limited data for me--only about 3 hours each of Ha and OIII--so I was battling noise and blue star halos the entire time. So please, forgive a bit of roughness at full resolution. I will definitely add more of both Ha and OIII for this bicolor, and I will collect SII as well for a HaSHO palette image, which will get its own page. I like to split narrowband targets into HaOIII bicolored images and HaSHO palette images when possible. Sometimes the bicolor just does not come out decently. The last couple for me have and I hope to maintain this approach.

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.
