M8 - Lagoon Nebula & M20 - Trifid Nebula in Hubble Pallet

Here is my version of a Hubble Pallet false color image of M8 & M20, the Lagoon and Trifid Nebulas. The image was created by mapping OIII and Ha data to the blue and green channels respectively. I then combined the Ha and OIII data to create a synthetic red channel. Finally I used a very helpful tutorial on Bob Franke’s website (http://bf-astro.com/hubblep.htm) to transform the colors in Photoshop into something replicating a typical Hubble Pallet image with it’s gold/yellow and turquoise/blue motif. It’s worth noting that this balance of colors is not the true color of the nebula you’d see in the sky but rather my artistic take with the data I’ve collected. The benefit of combining the data in different ways is not only a cool picture but I’ve also found that different combinations can highlight different aspects of the Nebula which aren’t as obvious in red-dominated true color images of the nebula. For a comparison you can see my earlier post of this object in HOO which more replicates the true color of the nebula. In the image you can see a number of M8’s Bok globules which are dark clouds of gas and dust where star formation is occurring including Barnard 88, 89 and 296. The Lagoon Nebula is an estimated 4-6 thousand light years away from us and 50-110 light years in size.

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.
