The Pelican Nebula : A Minimalist Processing Approach

The Pelican Nebula needs no introduction, being one of the most photographed summer objects. It is one of my favorites, especially since it offers a fantastic chromatic spectacle in narrowband. I wanted to take a deep exposure of the Pelican, so the project rose to 54 h (my longest exposure so far).

The SNR was impressive after integration. I therefore took only minimal steps in processing the image: no noise reduction was applied in the linear or non-linear stage, this is the original signal. No deconvolution sharpening was used. No star reduction technique either. I guess there are no shortcuts to improving signal to noise ratio: more exposure is better. The details are best seen in full resolution. The processing was completely performed 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.
