Saturn and its moons

Acquisition type: Lucky imaging

First capture of Saturn and its moons in LRGB. I struggled a lot with the deconvolution settings, eventually having to design an algorithm to derive the deconvolution matrix automatically. Cool development, but still not perfect.

It seems I was out of collimation. I'll see if I can compensate with a tweak of the deconvolution (it assumes isotropic matrices at this time, may make it able to do anisotropic deconvolution instead). Or reshoot after collimating the scope.

Alignment was tough too. The moons didn't move much this time, but they were very dim and the alignment routine wouldn't weigh them properly. Some manual tweaking was needed.

The combination was done in LB-RGB. It makes sense, but B has a lot more spatial resolution than other channels. So I combined it with luminance to build a synthetic luminance with higher spatial resolution. The improvement is noticeable.

I haven't taken bias, but the background noise shows that I clearly should have. I will do so later and upload a new revision... it's tricky because I used various gains all over the place, so I have to take quite a few sets of bias and organize the files a bit.

Frames per channel:

L: 10128 x 17ms (best 10%)

R: 6047 x 25ms (best 15%)

G: 6035 x 25ms (best 15%)

B: 8043 x 30ms (best 10%)

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.
