M17 Swan/Omega Nebula 2022 - Sagittarius

During a recent visit to my club's dark sight, I met a fellow astrophotography that encouraged me to acquire more data on my images. I have been averaging 3 - 4 hours on some of my recent targets. So during my last imaging session from my backyard, I decided to focus on collecting multiple nights of data on M17 to compare with the results of a previous imaging session. The original M17 only had 1hr 20min of data so it doesn't really compare with some of my more recent images, but I have to work with what I have. The new image of M17 is just shy of 10 hours.

So what did I learn from the process
1) Integrated image was much brighter
2) Noise was greatly reduced which made noise reduction routines very effective.
3) Some of the fainter nebulosity became very apparent
4) Finished images has more contrast and detail is sharper.

Conclusion: If you want better images spend the extra time needed to acquire this data. All this data was collected from my Bortlle 7/8 backyard but I'm still very pleased with the overall results. I often commented on many of my images that additional data may be beneficial and I now know that this is indeed true. It is therefore my intention to collect more data going forward.

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.
