M 42: The Great Orion Nebula (Fernando)

M 42: The Great Orion Nebula

With the raining season approaching it is very difficult to image the objects of summer, among them M-42. That is why I took advantage of this little chance the weather gave me and did this capture of M-42 using a wideband filtering system.

The subs were somewhat short in order to be possible to finish the job in one single night, because M-42 was rising late and and the Sun was rising early, besides the forecast for the next day had been cloudy with some rain.

Luminance:

6 x 30sec bin 1x1

8 x 60sec bin 1x1

12 x 300sec bin 1x1

RGB

8 x 300sec subs of each channel

Bias, Darks and Flats applied.

With the luminance frames I built a HDR image to preserve the details of the Trapezium, although the ideal would be to have complete LRGB images to do so.

The scope used was a TMB 92mm f/5.5 and the camera a ST8300M.

Pre-processing and processing in Pixinsight.

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.
