The Orion Nebula in Color

Pulled out the RASA 8 for first light on a CEM40-NUNC mount - the integrated profile of the NUNC mini on the mount is very much appreciated,

Stellarium 0.20.3 to scout and frame target. NINA to acquire 120 x 300s images @ -10c & 0g, ~85% were usable.

Blink / Subframe Select, Calibrated (60 Dark, 60 Flat, 100 Bias), Star Aligned all images with PixInsight. Used the Normalized Scale Gradient for integration.

Cropped, Linear Fit, DBE, TGVDenoise, MLT (made a clone here for stars), & EZ Soft Stretched. ABE, Background Neut, Color Calib, TGVDenoise, MMT, and Curves modified w/ & w/o masks to taste.

Cloned 300s data was Deconvoluted, masked with Star Mask, stretched, Star Mask inverted to replace with main image using Pixel Math to add the nebulosity around the stars.

3s data stretched and masked using GAME utility, this was used to replace oversaturated region of the core in main image using Pixel Math to add the nebulosity around the 3s core. PI and Resampled, Cropped, and Annotated.

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.
