NGC 2359

First time I try this object (Thors Helmet). Taken under suburban skies close to Madrid. Since this object is not so high in the sky right now I got some gradients mainly in OIII. I believe that I cannot improve the signal with this filter due to the LP. Most likely I will have to replace this filter by something more restrictive, ie 3nm.

12 hours taken in 600s frames. F6.5 and 700mm focal lengh.

Casco de Thor. Mi primer intento de fotografiar el Casco de Thor o NGC2359 desde cielos periurbanos 20 kilometros de Madrid. He utilizado la paleta HOO modificada, usando en el canal azul el 90%de Ha y el 10% de OIII. Este objeto no queda muy alto en el horizonte por lo que en mis cielos las tomas quedan con gradientes provocados por la contaminación lumínica. Creo que es el límite de lo que puedo sacar, aunque quizas más tomas eliminen parte del ruido los gradientes me impiden sacar mñás señal. Los filtros son Baader Ha de 7nm y OIII de 8nm auqnue quizas se pueda obtener una señal más limpia de contaminación luminica con filtros de 3nm (aunque mucho más caros).

He hecho 12 horas de tomas de 600s cada una a F6.5 y 700mm de focal.

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.
