Thanks for all the comments guys,
The presentation of the Saturn images reflects the angles Saturn appeared at as seen through the alt/az Dob as it rose. As the planet got closer to our meridian (near the right side of the image), it started to rotate quite quickly, so my normal 2 minute MOVs were reduced to 1 minute to stop field rotation during exposure.
The colours are as captured by the camera. I shot the still images in RAW format, maximised the saturation during development in Canon's Digital Photo Professional program, stacked in Registax, and saturation of the resulting TIF increased again in Photoshop.
The exposures for Saturn was 1/60th sec at ISO1600. Landscape Picture Style with maxed contrast, saturation and sharpness.
The exposures for Jupiter was 1/60th sec at ISO400 with the same Picture Style settings.
The exposures for Venus was about 1/500th sec at ISO100 with minimised contrast in-camera.
Lee, the planetary images are done using the Canon EOS 550D's 640x480 in-camera movie crop mode (ie the centre 640x480 of the sensor) at 60fps, with 4x worth of teleconverters at prime focus of the 12" Dob, for 1-2 minutes for each image. I haven't yet tried to hook up the laptop to the camera.
The Moon shot was a stack of 10 still images using the 550D at prime focus on the 12" Dob (1250th sec at f/5 1500mm. The zoomed in image is a crop of the original.
Cheers,
Tom
