Last night clear weather and tolerable seeing came along, so I went out with the Celestron and set up at a site where a hospital once stood. Despite being only ten arc-seconds across, I was seeing surface features on the disk on the lap top screen. As usual, I used a 2X TeleVue Barlow and ZWO Atmospheric Dispersion Corrector between the telescope and the ZWO ASI 290MC camera. I recorded four minute AVI files at a resolution of 548 X 548 pixels, with a frame rate in excess of 110 fps. I combine two of the best AVI files and used 6,000 of the 40,000 frames to get this image. The seeing was not great and had it been I would have used a 3X Barlow to partially compensate for Mars' increasing distance from Earth. At this time it's some 84,000,000 miles away.
