M24 The Sagittarius Star Cloud - B92 & B93 and More Stuff (Michael Feigenbaum)

M24 The Sagittarius Star Cloud - B92 & B93 and More Stuff

Here we have an image of Messier 24 and the surrounding area. M24 is located within the broad band of the Milky way and is rather low at my location culminating at 38 degrees.

There are a number of other smaller objects that are in this field of view including Barnard 92, 93 and 304 dark nebulae and NGC 6603, an open cluster of several hundred stars.

With regard to the acquisition and processing of these objects, I decided to try to go fairly deep with the image and I included some integration using a H-a filter. My intention with that was to simply enhance the overall image quality and not to try to isolate and feature hydrogen regions specifically. I was pleased with this outcome and I think the result is quite natural, I hope you will agree, lol...

The data I was able to collect was probably the best raw data I've ever managed. I did no linear noise reduction as I found any application of the various tools with masks to attenuate the NR effect resulted in a corresponding loss of detail. I did do a masked ACDNR immediately after stretching to compress the histogram a little and that's it for NR. My average FWHM was, across all of the filters, around 3 which is for me, simply the best I've ever managed.

I had intended to simply publish the full field of view. When examining the image, I thought the detail in B92 and B93 was nice enough that they merited their own crop. I liked that better than the full view.

Lastly, this is the first image I've ever done where I would have the courage to suggest that one might view this in full resolution for full effect. Usually, I am hoping people do not do that, lol...

I hope you like this one and any comments/criticism are encouraged!

CS and be well!

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.
