Astrophotography using a Argo Navis/ServoCAT equippped large aperture Dob

Argo Navis customer, Marco Guidi in Italy, sent me an image today of the
planet Uranus which he captured using his Argo Navis/ServoCAT equipped
20" f/4 Dob. See images attached below.

L'immagine finale è un resize del 200% e somma di 3750 frames,aggiungo un dettaglio che interesserà a pochi,il cuore del primario aveva una temperatura superiore di 1,5° rispetto alla temperatura ambiente.
which translates as :-

The final image is a resize by 200% and the sum of 3750 frames, I add a detail that will affect only a few, the core of the primary had a higher temperature of 1.5° with respect to the ambient temperature.
Thank you Marco and well done!
