The heart of Lagoon Nebula in Bortle 8 sky, SHO & starless.

Revision title: wStars

An combination of my available data on M8, my favorite target for summer. Wasted a lot of time on Helix Nebula and only a few data was collected on SII and OIII channels. The OIII data was taken on a night with 45% of moon illumination, and reflected light polluted nearly half of the fov and leave me no choice but to crop one third of the pic. The remote observatory to where my equipment will be sent locates in the southwest, where the rainy season often covers the whole summer, and wont find a chance for taken more data. Well, maybe next year or the year after, I can find good camp where I can shot some summer target.

After all , man changes, and the Galaxy does not.

Hey guys, I add a new revision with stars. Starless or wStars, pls tell me which one you like.

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.
