M8 and M20: The Lagoon and Trifid in a Sea of Dust

The sky near the galactic core is filled with dust, color, and amazing objects. These two, the Lagoon and Trifid nebula are among the most colorful in the sky. They are commonly imaged but from Oregon, I only get about one new moon cycle to try to image them myself. This data was taken on a warm summer night after encountering all kinds of equipment failures and problems. I was lucky to get this result though I had to toss out about 1/3 of my subs because the background light from town as the object moved west. The flat process worked almost perfectly for this data set and I did very little dithering so this image is 99% of the full 24 mm x 36 mm frame (only the extreme edges showed minor stacking artifacts.) C & C always welcome...enjoy.

PS Smoke, clouds, and moon have kept the scope inside so I had to try reprocessing this image and I quickly realized that I gave up too soon in my early versions. I left a lot of detail behind! The latest version was done in PI to bring out a lot more detail. Hopefully it works. Feel free to let me know what you think.

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.
