< Previous Next >I tried using extension tube setup earlier this night, but it didn't give satisfactory results, so I reverted back to original setup. Clouds were coming and going all the time and I had to take these images between clouds. Larger clouds came when I was doing RGB frames, so I did a quick set at 10fps. It came out quite good, so maybe next time I try it for all images. I still have hard time with the excess blue in the limb of the planet. I can't figure out where it it coming from, best bet is atmospheric turbulence. Partly it is also due to clouds forming in North pole. Seeing was good to mediocre.
