Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

Another image acquired under the cold, light polluted sky near Paris.

I am now using routinely remote control of outdoor computer using AnyDesk software.

The processing was performed in PI as follows :

For H & O channels :

- Images Calibration (Dark and Flat )

- Cosmetic Correction

- Image Registration

- Image Integration

- Mure Denoise

Then :

- Create HO color image

- Color balance on nebula

- ABC & DBE

- Deconvolution of Ha channel

- Going NL using HT

- Color Saturation range masked (and desaturate bkg)

- Color balance stars under star mask

- TGV denoise (no mask)

- Apply Ha Lum channel and HOO color channel (under star mask for version D)

Final image adjustments performed in Photo on Imac :

- levels adjustments

- adjust color looking using "selective color"

- crop and deflip

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.
