Lagoon & Trifid nebulae: adding 4 subs / Canon 6D mod + Canon 400mm L f/5.6 / SW star adv / 1600iso

After 4 Lozerian nights unsuitable for astro, the expected weather was quite good for 2 - 3 hours...unfortunately I had to play hide and seek with the clouds ! I wanted to image Lagoon and Trifid nebulae as it is impossible for me in my garden in Carcassonne.

1st experiment:

Ultimately, I could get only one shot , without autoguiding. So I decided to test a new time my basic technique: to copy "x" times this sub as if I could make last night x different subs of the same target (of course). 60 subs with different names. No darks. 19 flats. 20 offsets.

SIRIL 0.9.12 stacking no drizzle. I let you judge for yourself (?)

2nd experiment: 4 nights later, I could add 4 subs 120s each ISO 3200 to the 1st shot alone and proceed with conventionnal stacking.

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.
