2019

3 nights from 2h two 4h, one night for colours and 2 nights for lights.

Colours are poor, especially the red layer in faint extensions, I think that i had dust on the main mirror.

The second night i couldn't use the ligths because of dust. But i keeped the short lights i tooked for the center of this nebulae.

The 3rd night i got 13 pretty light frames, i'll try the colours next year again.

The extension is very faint so the dust in the first 2 nights destroyed all information in this level of the image, only in the blue layer I got some information.

2020

This year I took new colors. 30 min red, 30 min blue and free hours ha. I replaced the old colors by the new. Green is synthétic. I adjust the ha to the level of the red layer and then added 50% of each to get The new layer RHa.

Also I reduced chromatical noise like red clusters in the sky.

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.
