M42 the Orion Nebula – Post Processing Project

With the world as it is now we all should be home and since I have endless nights of clouds I choose to work on post processing with public data.

This is not my data; this data is from www.rawastrodata.com and the gear used was Orion 8” Newtonian f/3.9; Nikon D300 (Visible & Ha); Baader UHC Filter; Celestron CGEM mount. Settings were 30s/ 800 ISO, 44 Lights, 15 Darks, 23 Flats, and 20 Dark Flats. This image was processed with Deep Sky Stacker 3.3.2, Star Tools 1.6, and Canon Digital Photo Professional Version 4.

I first processed this image two years ago learning post processing and using Star Tools 1.3, this one was done with Star Tools 1.6 and it was vastly easier.

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.
