Hi Raffaello. Could you give some detail of how you created this image please?
Nick
Yes of course.
For the ingress phase and egress phase i have written an article on BAA Lunar Section circular september 2024 so that all is stated as procedure used. I an enclosing in my drive of google the link

Hi Raffaello. Thanks. I've read your very interesting LSC article and I can see that creating this took a lot of work. That said, I do think it is important to state that this is a reconstruction of the scene using composition techniques rather than an actual image. In my view this should be clearly indicated in the image description so that there is no doubt. Many of us will know that it would be very difficult, if not impossible, to get an image like this without using composition techniques but others, particularly beginners, will not.
Yes. In my images (see also my album) i stated this when i have published several images. See here

I wrote "I have imaged the Saturn occultation from Rome Italy. This image is before of the ingress. I used a Mak Cassegrain 18 cm , a HQY 5 III S C, color camera. Processing: Autostakkert III, Iris and Adobe Photoshop. The image is the composition given the notable difference in brightness between planet and moon of a correctly exposed image of the planet and one of the lunar limb. The resulting image is metrically correct for the position. A montage is underway of the various phases of the occultation which should be concluded this evening."
I agree, and indeed i published in LS circular my processing so that all can know. Ciao from Rome
Hi folks. These are a lovely series of images - thanks so much for posting them. But I do absolutely agree with Nick that any image creating as a composit / montage (or any other generative processing technique) should be clearly labelled as such in its description to avoid confusion.
