Grande Nebulosa da Órion (M42) NGC 1976 e Nebulosa do Homem Correndo NGC 1977 (Demison Lopes)

Grande Nebulosa da Órion (M42) NGC 1976 e Nebulosa do Homem Correndo NGC 1977

Minha primeira imagem de céu profundo, apesar de singela, foi um resultado que me deixou feliz, pois foi meu primeiro resultado depois de alguns meses de estudos, tentativas e dedicação.
Nebulosa da Órion (M42) NGC 1976 e Nebulosa do Homem Correndo NGC 1977.

Como foi uma imagem construída em paralelo com o aprendizado, foram feitas diversas sessões em datas variadas, de fevereiro à maio de 2023.
Devido ao Bortle 8 de Maceió, iniciei utilizando filtro UHC, em seguida o CLS e por último o L-enhance.

Ao total, foram 259 frames em exposições variadas, totalizando 5h58min de integração.

Algo que considerei um aumento na dificuldade da captura foi o fato da ASI585MC ser uma câmera planetária não refrigerada.

O processamento foi bem simples, apenas empilhei no DSS e tratei no Siril.
Pode-se perceber que não foi corrigido o Walking Noise e não foi feita Deconvolução para corrigir o aspecto das estrelas.

Assim vejo que essa imagem além de ser meu ponto de partida, é uma oportunidade para que eu compare minha evolução no futuro.

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.
