Lagoon Nebula, M8

Taken from my Bortles 6 patio in Odessa, Texas. My Canon Rebel EOS T5i is astromodified. I use the Astronomik CLS CCD EOS clip in filter to remove the sky glow from the city and oilfield around me.

I generate master calibration frames by calculating median's from 15 dark, bias, flat, and dark flat frames.

I was originally displeased with this image because of all the red objects in the background. I pinned it all as noise. The morning following my rendering in Photoshop, I was drinking coffee looking at it again and realized the majority of it is most likely distant stars from the Sagittarius arm of the Milky Way behind the Lagoon Nebula. The thousands of light years of galactic dust and gas between those stars and my camera is most likely filtering some of the shorter wavelengths of light, allowing the larger red wavelengths to pass more easily. I feel a little better about it now. I'm sure some of it is still noise, but not as much as I originally thought. Let me know your thoughts. This is still a work in progress, hoping to capture a few more hours on this throughout the summer.

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.
