Rosette nebula

N'ayant pu refaire des photos de la nébuleuse de la Rosette cet hiver, j'ai tenté un mix de deux séries d'images (à focales différentes) afin d'affiner la Luminance.

21x15' en Ha, reducteur x0,73. f=328mm (Bourgogne 2018)

13x15' en Ha, 6x10' en OIII&SII. f=450mm (Paris 2019).

Je suis finalement content du résultat obtenu, mais espère quand même l'améliorer une prochaine année...

Bon ciel à tous

Not having been able to redo photos of the Rosette Nebula this winter, I tried a mix of two series of images (at different focal lengths) in order to refine the Luminance.

21x15 'in Ha, reducer x0.73. f = 328mm (Bourgogne 2018)

13x15 'in Ha, 6x10' in OIII & SII. f = 450mm (Paris 2019).

I'm finally happy with the result, but still hope to improve it in a next year

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.
