IC 5070 - Pelican Nebula in SHO Palette (EasyQuest)

IC 5070 - Pelican Nebula in SHO Palette

Comments

For this project, back in summer season, I wanted a show piece for my first light of the William Optics FLT 132 version three. I decided on IC 5070 - Pelican Nebula in Cygnus. I decided on another SHO type image as I have seen on Google and Astrobin. I wanted a very clean image with very little denoising with AI so I went for broke and imaged as much as I can gather and discard the worst frames. The final results turn out as good I can get it! On the side note, this is my second processed version of the object as I posted my first version on reddit back in the summer. This one is processed differently so the results turned out better now. Enjoy~

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.
