Thank you all. There is a moon shot guide around, but I lost the link.
The full moon is at ISO200, 1/250s, f/8. Eclipse is at ISO400, 1/80s, f/8. You should go manual because metering gets fooled by all that black.
I did many attempts with almost any of my lenses, this one appears to be the best choice (recently had it as a gift on another forum... but can be found for few money). This lens is sharp in the middle, but not much in the corners and suffers of CA. However, you may obtain nice results (although not as nice) even with a kit lens at 200-300mm focal length.
I use a tripod (of course). I use Liveview for both checking focus (at max magnification), for waiting for stop of any oscillation (I have a cheap tripod), and to lock mirror to avoid even its effect. It is better to check focus because adapted old lenses may focus beyond infinity, so the maximum contrast is not at the end of focus travel, but slightly before (this could be true for modern lenses too, due to mechanical tolerances).
By the way, the moon too is moving, and it can be easily noted with longer focals.
Then I pp: conversion to b/w using green filter (the one that gives more detail), increase sharpness even if it reveals some noise, some slight contrast, etc.
However, both pictures are not done at the best time for the moon. In fact, the best detail can be obtained when the moon is not full, because light makes craters more evident, like in the next (without teleconverter, so some less detail):
