M8 and M20

New image of M8 and M20, with a Canon lens 100-400mm F5 @250mm.

Focus is much improved, so naturally stars are much better. Also, much more integration time.

Description: Much improved version. Used starnet to remove the stars and worked solely on the starless image. Arcsinh Stretch did a great job to preserve color, specially in the core of M8.

Description: Another take on the same data from almost a year ago. This was also another one picture I was never really happy with the end result. The colors were too saturated, ArcSinhStretch did many funny things with the stars. Now with Starnert V2, I could process the nebulosity completely separated from the stars. The colors are more realistic and less saturated.

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.
