Hi Gauthier,
As you have asked about craters, I am wondering if you have been able to achieve focus.
In your photos, there is an "erecting prism" adaptor shown between the eyepiece and the focuser. This device is used to show objects right way up when using the telescope for terestrial objects (trees, mountains etc).
Remove the adaptor and and just put the 20mm eyepiece into the focuser.
Adjust focus for a clear sharp image by turning either one of the black round knobs below the eyepiece on the focuser. You should be able to go from blurry image to crisp sharp image and back to blurry again. If you can not get it to focus as described then we need to discuss further.
You will be able to see plenty of craters with the 20mm eyepiece if you are getting it to focus correctly.
The shorter focal length eyepiecs will just increase the magnification.
Let us know if you can get a nice clear image of the moon with the 20mm.
