Sencilla toma de la Espada de Orión en la que he tratado de captar una buena aproximación a la típica estampa visual de M42 y M43 accesible con la mayoría de telescopios -salvando el colorido-. El principal propósito que persigo con capturas como esta es poner a prueba las posibilidades del equipo astrofotográfico en una sola toma, sin autoguiado y sin recurrir a la magia del procesado. Se aprecia claramente el nivel de deformación de las estrellas por la aberración comática que produce el telescopio ED 110 mm f/7 sin emplear un sistema adicional de lentes correctoras, así como la aberración cromática en forma de halos violáceos en la estrellas principales, aunque en este caso el cromatismo aparece reducido porque situé el sensor de la cámara ligeramente fuera de foco.

Esta imagen ha sido empleada para ilustrar un artículo que he escrito sobre la observación de la Espada de Orión con telescopios y con prismáticos, que se puede leer siguiendo el siguiente enlace:

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.
