    During long exposure astrophotographs imaging with AIRY refractors you normally use the field flattener inserted into the Hybrid-Drive focuser 50.8mm connection. If the camera used (cooled CCD or DSLR) is very heavy it may happen that the picture shows a slight deformation of the stars to the edges. This is not caused by the field curvature (since the use of the field flattener corrects it even with large sensors but by a slight flexure caused by the weight of the camera that does not remain perfectly on the optical axis of the telescope when you lock it with normal screws.
