Imaged under the bright Moon... The l-eNhance tri-band filter is really effective in combination with my ASI294MC but eben then the bright moon killed a lot of contrast :-) However, I tried to rescue some OIII and a first attempt to work with the data did not completely failed. At least it was the first astrophotography chance for me since weeks.

Description: "True Tone" Version of the same data but stacked and drizzled in PixInsight. No HOO composite this time as there is not really enough signal from OIII for a satisfying result.

Description: Bad weather - so, I was reprocessing and trying to learn new techniques. Here’s a new version of my "old" Crescent Nebula image based on my data from September 2020. I finally got out some nice blue in this HOO image by almost fully processing the Image in PixInsight. I split um the Ha and OIII channels with Pixekmath, removed the stars with StarXTermitator, recombined the Ha and OIII data, and pulled out the blue with a well-defined mask from the OIII channel. Some more tweaking in the curves and final touches on Photoshop. It´s still not the greatest image but a nicer version of this data than my very first, far too harsh try to force some OIII-blue into the image :-)

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.
