About Object:_______________________________________________________________

Cette nébuleuse est de taille apparente de 1.3°, soit près de trois fois celle de la pleine lune. En son sein se trouve NGC2244, dont les jeunes étoiles émettent un vent stellaire qui évide la région centrale et y comprime également le gaz, entraînant la naissance de nouvelles étoiles.

This nebula is 1.3° in size, almost three times the size of the full moon. Within it is NGC2244, whose young stars emit a stellar wind that avoids the central region and also compresses the gas, resulting in the birth of new stars.

Weather Conditions:________________________________________________________________________________

Total Cloud: 4%
Visibility: 10km (Stable)
Wind: 8k/h S/SE
Temp: 9°C
Dew Point: 9°C
Humidity: 100%
Transparence: 0.4
Seeing: 1.14

To be improved...:____________________________________________________________________________________
The aquisitions in SII and OIII show very pronounced halos around the stars.
The reason seems to be the mist deposit on the lens. And this, despite the use of a heating resistance. (Definitely poorly positioned)
These halos, impossible to remove completely give the stars a "limp" look

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.
