Little Rosette (Sh2-170)

Little Rosette Nebula (Sh2-170). I got some beautiful nights at the end of August and beginning of September, and set my sights on the Little Rosette, which I'd never shot before. To be honest, I was underwhelmed when the subs came in. Maybe it's my Bortle 8 skies, but I expected more on such a clear night, especially with a dual narrowband filter. I processed the data the next morning, and was still underwhelmed--there just wasn't a lot of depth or richness to the data. So I went back for more photons the next night. That second night really gave me more to work with, and I was able to draw out the bluish center from the red shell, while also revealing at least some of the surrounding Ha. A couple weeks later I grabbed some broadband stars to finish the image. I'm really happy with how this one came out.

Description: Applied Bill Blanshan and Mike Cranfield's Narrowband Normalization process to my dual-band data to put a little more "rose" in the Little Rosette, and hopefully achieving a somewhat more subtle and natural effect.

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.
