M42 The Great Orion Nebula (Fenton)

M42 The Great Orion Nebula

M42 The Great Orion Nebula. This image is a new iteration of data I collected on Feb. 16, 2014. This rendition is my first image processed using PixInsight (following Kayron Mercieca's False L+RGB workflow at lightvortexastronomy.blogspot.com). The image consists of 20x30" ISO400 subs for the core and 18x300" ISO400 subs for the field. It also includes 27 darks, 30 flats, 30 bias calibration frames. All sub exposures were pre-processed using PixInsight. The core was blended into the field using GIMP 2.9 along with some additional color and luminosity tweaking. It was a fun first go and I am very impressed with PixInsight. It's taken my imaging to a whole new level.

***REVISION B***

I reprocessed the data using Deconvolution on the luminance channel and noise reduction using TGVDenoise. Again, the core was blended into the image using GIMP 2.9 with additional color and contrast tweaking.

Thanks for looking, Fenton.

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.
