Jupiter, Ganimede's shadow and Io
The best I was able to cook from 9025 frames.
Aquisition time: JD2456726,16203704 (09.03.2014 19:53:20 MSK).
Image orientation: as in the sky
Canon EOS 60D (unmodded) with 1,25" Baader Planetarium UV-IR cut filter and 5x Barlow lens coupled to Celestron OMNI XLT150 Newtonian reflector riding on Skywatcher NEQ-6 Pro SynScan mount
Aperture 150 mm
Focal length (effective) 3750 mm
Tv = 1/60 seconds (movie crop 640x480 video recording mode)
Av (effective) = f/20
ISO 1000
Exposures: 1000 out 9025
Processing: Quicktime movies were converted to .AVI with SUPER video converter and processed in Registax6. Stacked images ware subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Cauchy type PSF, size 1,6 units, 9 iterations), enchanced by curves in Photoshop, wavelt sharpened in Registax and finally touched up again with levels and curves in Photoshop.
Note: I have finally found some reliable information concerning anti-aliasing filters in Canon cameras. Maybe I'm losing more details on it than on the atmospheric turbulence.
