All these pictures of were taken using the Meade 2x Barlow with a 10 inch Meade LX200 GPS telescope and a Logitech Quickcam Pro 4000.

I struggled a lot against dew. This meant I could not photograph Jupiter when it was between 63 and 79 degrees in altitude. How blessed our Southern Hemisphere amateurs are ...

30 April 2007: 23h38 Europa: 15 and 25 frames stacked out of 300

Europa apparent diameter: 0.9 arc seconds.

Using the 2x Barlow means each pixel covers 0.23 arc seconds ... so Europa is 4.1 pixels in diameter.

Fortunately the images of Ganymede are more promising ...

30 April 2007: 23h26 Ganymede: 50, 75 and 100 frames stacked out of 300

Taken using the Meade 2x Barlow at 1/5 second and 5 fps.

Jupiter was at an altitude of 38 degrees above horizon when Ganymede were photographed.

Ganymede apparent diameter: 1.6 arc seconds.

Using the 2x Barlow means each pixel covers 0.23 arc seconds ... so Ganymede is 6.9 pixels in diameter.

Fortunately the images of Ganymede are more promising ...

I will only fix the bad chromatic abberation when my images of Ganymede gets worthy of such attention. (Just notice the blue fringe at the top of Ganymede and the red fringe at its bottom).

The third processed Jupiter image I took in 2007: 1 May 2007 00h31 - local time

Apparent diameter: 43.2 "

Captured in Alt/Az mode using 2x Meade Barlow.

Here is the unprocessed 2.4 MB AVI of Jupiter.
