Another evening photographing Jupiter. This time with the BAS Celestron 9.25″ on the 23rd Jul. Separate red, green and blue avi’s of 45 seconds each were taken, stacked in Registax and then combined in the GIMP (an open source imaging program).
The ’seeing’ was pretty good, but once again, the very low altitude limited the detail in the picture. However, the Great Red Spot is just visible on the right had side of the planet.
Processing a picture taken some 10 minutes earlier shows more of the GRS and comparing the images also reveals the speed that the planet is rotating. This image is in red light only and I’ve flipped it both horizontally and vertically to match convention.
