Meade LX90, F/D 35 (3x barlow), TouCam pro II (no filter).
Staking of 1300 frames, 1/25sec each. Processing: wavelets (registax3).
Six days before opposition
The seeing was fair tonight. I still don't have a dewshield for my Meade LX90 ... I had to fight with a hairdryer against the dew deposit on the correcting lens.
The image was acquired with the help of Aymeric Berrenger.
Note the change in the rings appearance since january 2005.
Fully open in 2003, the rings will close throughout the decade and will be edge-on in September 2009.
Meade LX90, F/D 27 (2x barlow), TouCam pro II + IRB filter.
Staking of 600 frames, 1/25sec each (Skeye). Processing: wavelets (Iris)

This view was obtained from 20 AVI files. The "field rotation" due to the altazimuth configuration of the telescope was very apparent. This had to be corrected manually.
