Uranus
The following Uranus image was acquired at the Cassegrain focus of my Celestron Ultima 9.25 with a long exposure version of a Philips ToUCam Pro webcam (Steve Chambers modification). A TeleVue 2.5x barlow lens was used. The seeing conditions were not too turbulent. A Baader IR blocking filter was also employed. The image was generated from a stack of 40 separate frames, each of 2 seconds duration, acquired using K3CCDTools. A beta version of Registax 2.0 was used to process the final image.
