Light cloud covered much of the sky at sunset .I just managed a 2 star alignment of the lx90 at 5.25 pm and used the lpi =x2 barlow to capture the very end of the double shadow transit of europa and io at 5.35pm. The gain was set to 66 to enhance the brightness of the two moons . This washed the shadows out a bit but they can still be seen .Quality was set to 90% and exposure 0.177s. There wasn't time to experiment with the settings and the sky was still in between twilight and darkness. Images were stacked as they were captured by autostarsuite software and enhanced in registax.
